Zero operative mortality rate in 109 consecutive elective aortic operations performed by residents.

One hundred and nine consecutive elective abdominal aortic operations were performed at the Veterans Administration Medical Center San Diego between 1984 and 1987. All of the operating surgeons were residents in general surgery who were assisted by attending staff. The mean age of the patients was 66.1 years and 34 patients were 70.0 years or older. The indication for operation was aortic aneurysm in 69 and aortoiliac occlusive disease in 40. Fifteen patients underwent highly complex procedures. The mean duration of operation was 5.6 hours, mean aortic clamp time was 72 minutes and mean volume of blood replacement was 1,186 milliliters. There was no operative mortality. Twenty-nine patients had 32 nonfatal complications. Patency of the graft was 100 per cent at discharge. We conclude that excellent clinical results with complex elective aortic operations can be achieved by surgical residents with appropriate supervision.
