We retrospectively reviewed the records of 88 patients who underwent a total of 95 in-situ bypass operations. Seventy-eight percent were diabetics, 56% hypertensives, 23% had a history of a myocardial infarction, 18% a previous stroke or transient ischemic attack, and 19% a renal transplant. Eighty-eight percent had general anesthesia. Eighty-four percent of the operations extended distal to the popliteal trifurcation, with an average operating time of 5.12 +/- 1.25 hours and blood loss of 354 +/- 239 ml. The overall mortality was 4.2%, with two deaths due to wound sepsis and two deaths due to congestive heart failure. The perioperative myocardial infarction rate was 6.3%. The average age of the patients who died was significantly greater than the age of those who survived (78.2 +/- 17.7 years vs. 59.9 +/- 14.8 years, p less than 0.05). The Goldman risk index was not helpful in predicting cardiac complications. The results show that patients undergoing in-situ bypass operations are at high risk for cardiovascular complications. Aggressive perioperative evaluation and management similar to that shown to reduce such complications in abdominal aortic aneurysm surgery should be helpful.
