A minimally invasive surgical technique for repair of aortic aneurysms and aortoiliac occlusive disease was studied. A small periumbilical incision, nondisplacement of the small bowel outside the abdominal cavity, and hand-sewn anastomoses are performed without laparoscopic assistance. This technique may reduce the duration of hospital stay.

Suprarenal or supraceliac aortic clamping during repair of infrarenal abdominal aortic aneurysms can be complicated by renal, hepatic, and intestinal ischemia. To determine whether suprarenal or supraceliac clamping increases morbidity and mortality we retrospectively reviewed our recent nonrandomized experience. Between January 1993 and December 1998, 716 patients underwent elective (n=682) ...

When one is faced with impending rupture, repair of an aortic aneurysm cannot be delayed. In the presence of coexisting intra-abdominal sepsis, traditional therapy would call for aneurysm exclusion and axillofemoral bypass grafting. Consequences of this choice of treatment include limited long-term graft patency and recurrent prosthetic infection. Autogenous deep ...
