The Issue Whether disciplinary action should be taken against Respondent's license to practice medicine based on allegations that Respondent violated the provisions of Subsections 458.331(1)(m) and (t), Florida Statutes, arising from his treatment and care of Patient M.R., as alleged in the Administrative Complaint in this proceeding.
Findings Of Fact Effective July 1, 1997, Petitioner is the state agency charged with regulating the practice of medicine pursuant to Section 20.43, Florida Statutes, and Chapters 456 and 458, Florida Statutes. Respondent is and has been at all times material hereto a licensed physician in the State of Florida, having been issued license number ME 0077248. Respondent is a vascular surgeon, who is not board-certified in his area of practice. On November 27, 2000, Patient M.R., a 70-year-old male, was admitted to ORMC for a right-side carotid endarterectomy. Patient M.R. initially presented to Respondent in October 2000 with a number of health conditions, including chronic obstructive pulmonary disease (related to a 54-year history of smoking), cerebral vascular disease, atherosclerotic changes, and hypertension. Patient M.R. had a significant cardiac condition which resulted in a bypass procedure. It was determined at that time that Patient M.R. had significant stenosis in both carotid arteries which would require Patient M.R. to undergo two separate procedures, known as carotid endarterectomies. The left carotid artery was the subject of the first procedure in October 2000. Patient M.R. tolerated this procedure with no complications. Subsequent to the first carotid endarterectomy, but prior to the second, Patient M.R. suffered a transient ischemic attack (TIA), which is commonly referred to as a "mini-stroke." The symptomatic clinical presentation placed Patient M.R. in a high-risk category for peri-operative stroke. Respondent performed a right carotid endarterectomy on Patient M.R. on November 27, 2000. This requires the clamping of the artery in two locations, using a shunt to allow for the flow of blood. The incision must be made length wise in the controlled portion of the artery using an instrument to clear out the interior or lumen of the artery. This is done to reduce the stenosis and allow for better blood flow, without disbodying any particle from the wall of the artery. Once this is completed, the incision is patched, the clamps and shunt are removed, and the outer skin incision is closed. During the course of the above-described carotid endarterectomy, Respondent used a patch angioplasty with intra- operative shunt, which was manufactured from a pediatric feeding tube, and peri-operative neurologic monitoring. Immediately after the operation, the patient appeared to tolerate the procedure well, but was lethargic. Patient M.R. exhibited good movement in all four extremities and appeared to be neurologically intact, although he underwent extreme fluctuation in blood pressure. Patient M.R. was placed on ventilator support. The next morning, November 28, 2000, Patient M.R. had swelling and a hematoma in his neck on the right side, in the area of the incision. Respondent returned Patient M.R. to surgery, for exploration and evacuation of the hematoma. During the course of this second operation, Respondent observed a lot of swelling and edema in the operative site, but not much blood. Respondent evacuated the hematoma, and the carotid artery was found to have good blood flow. Later in the evening on November 28, 2000, Patient M.R. developed an acute neurologic deficit and was returned to the intensive care unit (ICU) at ORMC. Respondent ordered a Computerized Tomographry Scan (CT Scan) of the patient and an arteriogram. The results of the CT Scan showed a probable right occiptal infarct (stroke). The arteriogram showed significant occlusion of the right carotid artery extending to the carotid siphon. Patient M.R. was returned to the operating room in the early morning hours of November 29, 2000. Respondent made the decision to reopen the surgical area in an effort to resume blood flow in the right carotid artery that was seen to be occluded on the angiogram. Assisting Respondent on this November 29, 2000, procedure were John Horowitz, M.D., a board- certified vascular surgeon with nine years of experience, and Joseph Muller, M.D., a third-year general surgical resident at ORMC. During the November 29, 2000, procedure, Respondent reopended the previous incision in the skin and partially opened the patch that had previously been used over the carotid artery itself. Respondent performed a thrombectomy using a Fogarty "balloon" catheter in an effort to extract any debris that was causing the stenosis in the carotid artery. The balloon is placed into the carotid artery itself and is pushed up into the artery until it has passed whatever occlusion is present. Then the balloon is inflated and pulled back out, pulling with it any debris that is located within the artery. Near the conclusion of this November 29, 2000, procedure, a small piece of tubing was discovered in the surgical field. The piece of tubing was handed to Dr. Horowitz, who examined it and then placed it on the surgical tray. This piece of tubing was the same size, slope, and material cut from the feeding tube which was used as a shunt in the first surgery on November 27, 2000. There is conflicting testimony regarding the precise size and location of this piece of tubing that will be discussed below. What remains undisputed based upon the record in this case is that Respondent completed the surgical procedure on November 29, 2000, by closing the incision in the carotid artery and also in the skin of the neck. Dr. Muller is currently a surgical resident at ORMC, as he was at the time of the November 29, 2000, procedure. Dr. Muller testified that he had approximately two years and five months of residency training prior to the procedure in question. He estimated that he had observed approximately ten to 15 carotid endarterectomies. Dr. Muller testified that he observed a clear and slightly opaque piece of pediatric feeding tube coming out of the lumen of the artery as Respondent was evacuating debris after the inflation of the Fogarty balloon catheter and after about three passes of the catheter. Dr. Muller also testified that the piece of tubing in question was two or three centimeters in length. The other witnesses to this event testified that the piece in question was two to three millimeters in length. Dr. Muller's description of the position of the surgeon and assistant surgeon was also contrary to that of the other witnesses. Dr. Muller also testified that he did not know Patient M.R.'s medical history or his previous hospital course of treatment. Dr. Horowitz, the senior physician assisting, is a board-certified vascular surgeon who has performed several hundred carotid endarterectomies. He testified that he was called in by Respondent to assist on the surgical procedure which took place in the early morning hours of November 29, 2000. He found the piece of tubing located somewhere within the surgical field, remote from the carotid artery. He was certain that it was after Respondent had cleared the artery with the use of the Fogarty balloon catheter and had cleared the surgical wound. Dr. Horowitz testified that he saw a piece of tubing among the debris that had been evacuated from the surgical wound. It was not in the lumen of the artery. He picked up the piece of tubing in question with his thumb and forefinger and examined it. He testified that it was approximately two to three millimeters in length. He agreed that the material was consistent with the pediatric feeding tube that was used to create a shunt for the first procedure. Dr. Horowitz's testimony is credible and persuasive. Dr. Horowitz also gave his opinion that based upon his observation of the November 29, 2000, procedure, he did not believe that Respondent deviated from the standard of care in his treatment and care of Patient M.R. Patient M.R. was returned to the ICU, where he deteriorated and showed evidence of complete lack of brain stem reflexes. Patient M.R. was later pronounced brain dead, and he subsequently died on November 30, 2000. Gregory Schreiber, M.D., was the anesthesiologist who was present for a portion of the November 29, 2000, procedure. Dr. Schreiber testified that he was present during the beginning portion and the end portion of the procedure, when anesthesia is introduced and when anesthesia is abated. He was not present in the operating room when the piece of tubing was found. Further, there was a drape that separates the operative field from the anesthesiologist during the course of this procedure, which would have prevented Dr. Schreiber or his assistant from being able to see into the operative field directly. Dr. Schreiber noted that Patient M.R. was considered a very high-risk patient, whose multiple co-existent diseases posed a constant threat to his life when he presented for this surgery. In addition to the testimony outlined above, Petitioner also introduced three affidavits into evidence. One affidavit was that of Lata Bansal, M.D., a neurologist who was brought in for consultation after the November 29, 2000, procedure. Dr. Bansal swore in her affidavit that when she first saw Patient M.R. he was already brain dead. She otherwise did not have specific recollection of Patient M.R. The affidavit of Peter D. Taylor, M.D., a cardiac specialist, stated that he recommended a Thallium stress test for Patient M.R. prior to carotid surgery. The stress test was conducted on October 17, 2000, and revealed no ischemia but moderately decreased left ventricle function. Because he had no ischemia, Dr. Taylor opined that Patient M.R. was at an increased but acceptable risk for carotid surgery. The affidavit of Marita Lu, Registered Nurse, who was present during the November 29, 2000, procedure, stated that she could remember very few details of Patient M.R.'s case, other than she has the "impression" that something was recovered from the wound and that when she asked whether there was a specimen, she was told there was no specimen. Nothing in her affidavit indicates to whom she asked this question regarding the specimen nor is there any indication who responded to her question. Respondent is a board-certified general surgeon who is eligible for a special certification in vascular surgery and who was working at a vascular surgery group in Orlando, Florida, as of October and November of 2000. Respondent no longer practices in the State of Florida. He currently is an assistant professor of surgery and director of endovascular surgery at Creighton University in Omaha, Nebraska. Respondent described in detail each of the three procedures he performed. On November 27, 2000, the original procedure on the right carotid artery proceeded in routine fashion. Respondent provided an exemplar, which was admitted into evidence, of a pediatric feeding tube which is substantially similar to the pediatric feeding tube utilized in the November 27, 2000, procedure on Patient M.R. He utilizes a portion of the pediatric feeding tube as a shunt in his carotid endarterectomy procedures. He demonstrated at the final hearing that the pediatric feeding tube itself is so flexible as to be incapable of breaking. The only means of cutting it down is through the use of surgical instruments. He also indicated that there was no way to further cut down the tubing once it had been placed. The scrub technician cut the pediatric feeding tube into the appropriate length to be used as a shunt during the November 27, 2000, procedure. Respondent recalled that prior to this particular procedure, the tubing in question was not originally cut down to the appropriate size. It had to be cut down while in the operating room. It is during this cutting of the tubing that a tiny sliver, approximately two to three millimeters in length, was removed from the larger piece of tubing and entered the surgical field. Respondent did not know and did not have any way of knowing that the piece of tubing had entered the surgical field, as he was focused on preparing the artery itself for its incision while this tubing was cut. Respondent testified that the pediatric feeding tube in question was cut down to size before any incision was made in the carotid artery itself. Respondent performed the November 27, 2000, procedure as he normally does. After the procedure, Patient M.R. experienced extreme fluctuations in blood pressure. This can occur in patients due to multiple factors involving the nervous tissue and blood flow in the carotid artery, but there is no specific explanation for why it does happen. Subsequent to the November 27, 2000, procedure, Respondent monitored Patient M.R., addressing the extreme fluctuations in blood pressure along with the consulting physicians referred to above. Respondent noted that Patient M.R. developed a hematoma subsequent to the first procedure. He made a determination that the best course for Patient M.R. would be to evacuate the hematoma. In Respondent's opinion, evacuating the hematoma would speed up the healing process. Respondent performed this procedure on November 28, 2000. Patient M.R. tolerated this procedure well, and there was nothing remarkable about the procedure itself. Respondent palpated Patient M.R.'s artery during the course of this procedure and used the Doppler to reinforce his findings on palpation. A Doppler signal gives more specific information about the varied nature of blood flow in the internal and external carotid arteries. It was not Respondent's standard practice, nor is it necessary, to create a medical record that palpation of the artery has occurred, since it is such a basic and common occurrence that its notation on the record is not deemed to be necessary. Respondent continued to follow Patient M.R. subsequent to the November 28, 2000, procedure. When it was determined that Patient M.R. had suffered a stroke, Respondent was left with a choice of either doing nothing, or reopening the artery in an effort to save Patient M.R.'s life. Respondent chose to reopen the artery in an effort to determine whether anything could be done to save Patient M.R. Respondent opened the prior incision in the carotid artery on November 29, 2000, and inserted the Fogarty catheter in order to evacuate any debris that was located within the carotid artery. Respondent testified that it was at about this time that the piece of tubing was found; however, he further testified that he did not see the tubing in question come from the lumen of the carotid artery. Respondent's testimony is credible. It was Respondent's opinion testimony that the piece of tubing in question was located in the subcutaneous tissue outside of the artery. Its exact location within the various layers of subcutaneous tissue was not observed during the procedure. It was not possible for the piece of tubing in question to have entered the artery at this time. There was no evidence to suggest that the piece could have migrated into the artery at a later time. James Dennis, M.D., is a board-certified vascular surgeon who is the chief of the vascular surgery department at the University of Florida in Jacksonville, Florida. Dr. Dennis has sufficient education, training, and experience to qualify as an expert in vascular surgery under Florida law. Dr. Dennis testified that he reviewed all of the pertinent medical records concerning the treatment and care provided by Respondent to Patient M.R. and that based upon his review of these records and based upon his education, training, and experience, it was his opinion to within a reasonable degree of medical probability that Respondent deviated from the accepted standard of care in his treatment and care of Patient M.R., which constituted a violation of Subsection 458.331(1)(t), Florida Statutes. Dr. Dennis also testified that in his opinion, Respondent violated Subsection 458.331(1)(m), Florida Statutes, in that he failed to compile appropriate medical records reflecting the treatment and care provided to Patient M.R. Dr. Dennis' standard of care opinions were based on several factors. First, it was Dr. Dennis' opinion that based upon the contents of the chart, the only time that the piece of pediatric feeding tube could have entered Patient M.R. was during the course of the November 27, 2000, procedure. Dr. Dennis testified that in his opinion, Respondent deviated from the standard of care in allowing the piece of pediatric feeding tube to enter Patient M.R.'s body. This would be his opinion even if Respondent did not see the sliver of tubing in question enter Patient M.R.'s body and even if the piece of tubing in question were so small and translucent as to be practically invisible. Dr. Dennis also testified that in his opinion, Respondent deviated from the standard of care during the November 28, 2000, procedure in that he failed to adequately palpate the carotid artery. Dr. Dennis was critical of Respondent's use of a Doppler to assess Patient M.R.'s pulse. In Dr. Dennis' opinion, the use of the Doppler was indicative a weakening pulse rate and that the proper practice would have been to palpate the artery by touch rather than by using a Doppler instrument. Dr. Dennis was also critical of Respondent during the November 28, 2000, procedure for his failure to find the piece of tubing in question. It is Dr. Dennis' opinion that the piece of tubing had to have been located within the lumen of the artery and that had Respondent adequately palpated the entire length of the carotid artery during the November 28, 2000, procedure, he would have located the piece of tubing within the artery and could have taken appropriate steps to remove the piece of tubing before Patient M.R. suffered his stroke later that night or during the early morning hours of November 29, 2000. Dr. Dennis' opinion that the piece of tubing in question had to have been located in the lumen of the artery was also based upon his assessment of the procedures performed. He discounted the theory that the piece of tubing was located within subcutaneous tissue outside of the artery because, in his opinion, the piece of tubing would have been discovered either during the November 28, 2000, procedure or earlier in the November 29, 2000, procedure if it had been outside the artery. However, according to Dr. Dennis, based upon the timing of when the piece of tubing was found, the tubing itself had to have been located within the lumen of the artery until it was removed in the November 29, 2000, procedure. Dr. Dennis also rendered the opinion that not only was the piece of tubing located within the lumen of the carotid artery, but that the piece of tubing is directly related to the stroke which Patient M.R. suffered later that day or the following morning, which caused his death. Dr. Dennis testified that the piece of tubing became lodged in Patient M.R.'s carotid artery and that as blood flowed by it, platelets attached to the tubing, slowly building up with the carotid artery, until Patient M.R. experienced 100 percent stenosis in the right carotid artery, leading to his stroke. In sum, Dr. Dennis' opinion was that Respondent deviated from the standard of care by allowing a piece of tubing to enter Patient M.R.'s carotid artery and that it was this tubing which lead to Patient M.R.'s stroke and ultimately his death. This is in spite of the fact that Dr. Dennis was not able to state within any degree of medical probability how the sliver of tubing could have entered the artery. Dr. Dennis also rendered an opinion during his final hearing testimony that Respondent deviated from the standard of care because he did not secure the piece of tubing at issue in this case and see to it that the tubing was sent to the pathology laboratory at ORMC for analysis. Morris Kerstein, M.D., a board-certified vascular surgeon, reviewed all of the pertinent medical records reflecting the treatment and care Respondent provided to Patient M.R. Dr. Kerstein had been practicing for 35 years, and he is currently the chief of the vascular surgery department at the Veteran's Administration Hospital in Philadelphia, Pennsylvania. Dr. Kerstein has sufficient education, training, and experience to qualify as an expert in vascular surgery under Florida law. Dr. Kerstein's opinion based upon his education, training, and experience is that Respondent did not deviate from the standard of care in his treatment of Patient M.R. First, Dr. Kerstein testified that in his opinion, Respondent's conduct during all three procedures at issue was appropriate. As to the November 27, 2000, procedure, there was no way for Respondent to be aware that the piece of pediatric feeding tube had entered the operative field. It was too small to be noticed, and it was of a translucent color which made locating it extremely difficult. He was not critical of Respondent for not cutting the tubing himself. He testified that if, in fact, the sliver of tubing entered the surgical area as a result of the scrub technician cutting the tubing, and a two to three millimeter fragment jettisoned into the surgical field, this would not constitute a deviation from the standard of care by Respondent. Dr. Kerstein testified that he felt the November 28, 2000, procedure was performed appropriately as well. He testified that it was not a deviation for Respondent to use a Doppler to feel for pulses in the arteries, and to the contrary, it reveals that Respondent was being meticulous beyond what the standard of care requires. He opined that Respondent certainly would have palpated the arteries in question, and to suggest otherwise based on the absence of a note to that effect is not an appropriate conclusion to draw. Dr. Kerstein rendered the opinion that he did not believe that the piece of tubing in question was located within the lumen of the artery of Patient M.R. He testified that there was no way for the tubing to enter the artery because the sliver in question came off of the longer tubing before an incision was made in the carotid artery. There is therefore no reasonable explanation as to how the piece in question could have entered the carotid artery in the first place. Dr. Kerstein also disputed the theory that not only was the piece of tubing located within the lumen of the artery, but also the piece in question actually caused Patient M.R.'s stroke. Dr. Kerstein relied principally on the radiographic studies. Both the CT Scan of the brain and the angiogram taken late in the evening of November 28, 2000, revealed a right posterior occipital infarct. The posterior of the brain is the back of the brain, and if the infarct was located there, it means that the cause of the stroke had to be something other than an occlusion in the carotid artery. This is because the arteries that feed the back portion of the brain are the basilar and vertebral arteries, not the carotid artery. Therefore, there could be no possible causal connection between the sliver in question and Patient M.R.'s stroke. Dr. Kerstein's opinion as to the cause of Patient M.R.'s stroke focused on his personal history rather than on the events of November 27, 2000. He noted that Patient M.R. presented with severe atherosclerotic changes, indicative of an advanced disease process. He noted that Patient M.R. suffered from chronic obstructive pulmonary disease, which was the product of his 54-year smoking history. He also noted Patient M.R.'s significant cerebrovascular disease. He also stated that thrombosis (or clotting of the blood) is a known complication of this procedure and can happen for several plausible reasons other than a sliver of tubing in the artery. All of these conditions conspired to predispose Patient M.R. to suffer a significant event such as the stroke he suffered on November 28 through 29, 2000. Dr. Kerstein also noted that the piece of tubing was completely inert, and given its size and its location in the subcutaneous tissue outside of the carotid artery, the tubing would have had no impact whatsoever on Patient M.R.'s prognosis. The tubing in question is an example of inert material that can remain inside the body, such as the case of a bullet which is located too close to the spinal cord to allow for an operation to remove it, without causing the body any harm. Dr. Kerstein had no criticism of the medical records Respondent kept regarding the treatment he provided to Patient M.R. He specifically noted that the records were accurate and honestly reflected what had occurred during the procedure. The fact that no foreign object was noted in the first two procedures was appropriate because at that point, he had no reason to suspect the presence of a foreign object. The lack of reference to a cause of Patient M.R.'s atypical post-operative course was appropriate because in fact Respondent could not have defined a single reason why Patient M.R. was reacting the way he did. Finally, the operative note from the November 29, 2000, procedure was appropriate, as it also honestly and accurately depicted what had occurred; he made a specific comment on Respondent's note that the sliver was not indeed from the lumen, but that the exact location was unclear, finding this to be an unambiguous statement of fact. Dr. Kerstein also disagreed with the state's position with regard to the responsibility for maintaining possession of the piece of tubing post-operatively. Dr. Kerstein testified that it was the responsibility of the circulating nurse, an employee of the hospital, to arrange for the piece of tubing to be sent to the pathology lab for examination. The evidence is insufficient to support Petitioner's contention that the pediatric feeding tube sliver at issue caused Patient M.R. to suffer a stroke because of its location within the carotid artery itself. Radiographic studies were performed on Patient M.R. after the stroke. A CT Scan performed on November 28, 2000, revealed an acute right posterior cerebral artery distribution infarct. Further, a cerebral angiogram was performed on November 28, 2000, and revealed "markedly diseased circulation particularly in the right vertebral and basilar arteries." This note also revealed: "Severely diseased posterior fossa circulation." Based upon the location of the infarct in Patient M.R.'s brain, the cause of the stroke had to have been either the vertebral or basilar arteries that supply blood to the posterior part of the brain. In view of all the evidence, the expert testimony of Dr. Kerstein, together with that of Dr. Horowitz, was more persuasive than that of Dr. Dennis in regard to the standard of care and Respondent's actions in this matter.
Recommendation Based on all the evidence of record, it is RECOMMENDED that the Board of Medicine enter a final order holding that the evidence is not clear and convincing that Respondent has violated either Subsections 458.331(t) or (m), Florida Statutes, in his treatment of Patient M.R. and that the Administrative Complaint be dismissed.
