Results of 256 consecutive abdominal aortic aneurysm repairs using extraperitoneal approach.
Two hundred and fifty-six consecutive abdominal aortic aneurysms were repaired using three approaches for extraperitoneal exposure of the aorta and iliac vessels from February 1990 through September 1998. The perioperative mortality rate was 3.1% in 228 elective repairs and 14.3% in 28 ruptured cases. The initial 23 cases were repaired using Sicard's method. The duration of endotracheal intubation was 1.0+/-2.8 h, alimentation initiation was 2.7+/-1.6 days, and narcotic requirements were 1.2+/-1.1 times. Following these initial cases, we employed Williams' method for 192 abdominal aneurysms, however; repeated incisional pain and three cases of deforming bulge led us to avoid dividing muscles. In the last 13 cases, our approach was performed without muscle dividing. The narcotic requirements decreased to 0.3+/-0.7 times. As for postoperative complications, the larger skin incision approach had no shower embolism. However, the shorter skin incision had four cases of shower embolisms, one lymphorrhea and one vascular trauma by the aortic clamp. The extraperitoneal approach offers certain physiologic advantages with minimal disturbance of gastrointestinal and respiratory function. We believe that this method is useful for rapid approach to the proximal aorta in case of emergency. Postoperative wound complications could be prevented via an oblique incision without muscle dividing.
