Aortocoronary bypass surgery: a 7-year follow-up.

Follow-up of 748 consecutive patients who underwent aortocoronary artery bypass grafts was obtained for 5 to 94 months (average, 59 months). Operative mortality of 2.5% did not vary with number of vessels bypassed. There was a linear 3.5% annual recurrence rate of angina, and average annual late infarction rate of 1.4%. The cumulative survival rates did not differ for the number of grafts performed or for men and women, but did differ for left main coronary stenosis and impaired ejection fractions. The late cumulative survival rates for the entire group approached those of the general U.S. population.

Mammary-coronary artery anastomosis for myocardial revascularization.

My experience with the use of mammary-coronary artery anastomosis for myocardial revascularization in 1,500 patients over a nine-year period has been described. The procedure was used in approximately 85% of patients undergoing coronary bypass surgery, but mammary arteries accounted for only one third of the grafts. Patency rates as determined by arteriography performed from two weeks to seven years after operation were more than 95%. No late alterations in the mammary artery grafts have been seen. Clinical results have been so gratifying that I regard the procedure as the one of choice for bypass of stenosis of the left anterior descending coronary artery.

Training in microvascular surgery.

This is the first report that analyzes the time required for a general surgeon to master the technique of anastomosis of arteries with diameters of 1.25 and 1.5 mm. Probes of 0.25 mm gradation were used to calibrate the lumens of the arteries and the anastomoses. The Zeiss microscope was used at 25 magnifications to repair a transverse division of the abdominal aorta of a 120 gram rat. Fifteen hours were required for the surgeon (S.H.) to become accustomed to the use of the equipment. Then a series of 40 rats were operated upon and kept alive from 1 to 6 weeks. Patency rate was 100% (40 of 40). No anastomosis was less than 1.25 mm in diameter. After the initial practice period of 15 hours, quality of anastomosis was unchanged, but time required to perform it diminished from 45 minutes to 15 minutes during the course of 40 procedures that occupied 35 laboratory hours.
