Aortoiliac reconstruction combined with nonvascular operations.

Seventy-six patients with aortoiliac reconstruction and associated intraabdominal procedures were compared with 445 patients with aortoiliac revascularization alone to provide information about the associated morbidity and mortality of adding a nonvascular procedure to aortic reconstruction. Patients with aortoiliac reconstruction for limb salvage had a significant increase in complications when an abdominal procedure was performed in association with aortoiliac reconstruction (66 percent versus 14 percent, p less than 0.01). Additionally, patients with elective aortoiliac reconstruction had a significant increase in mortality when an abdominal procedure was performed in addition to aortoiliac reconstruction (9 percent versus 3 percent, p less than 0.01). A small bowel obstruction and a pancreatic pseudocyst occurred as a direct result of the associated abdominal procedure. None of the deaths could be directly attributed to a concomitant abdominal procedure. The demonstration of an increase in morbidity and mortality with the addition of nonvascular procedures to aortoiliac reconstruction, even though certain subgroups of patients underwent aortic revascularization, suggest that the surgeon must carefully weigh the benefits and risks before combining vascular and nonvascular operations.
