FOR ANY evolving surgical procedure, there is a constant need for critical review of results. This is particularly true for arterial reconstruction, where the final word, in terms of survival of the part, may not be written for several years.
The Peter Bent Brigham and West Roxbury Veterans Administration hospitals are affiliated teaching institutions whose surgical services have been engaged in arterial reconstructive surgery for the past 15 years, treating a heterogeneous atherosclerotic population with a variety of arterial reconstructions.
