Multicenter prospective study of nonruptured abdominal aortic aneurysms. I. Population and operative management.

摘要: This article describes the patient population and operative management of 666 patients with nonruptured aneurysms abdominal aorta. Statistical significance variables was determined by chi-square test logistic regression analysis. There were no statistically significant differences (p greater than 0.05) in mortality rate for aortic aneurysm (AAA) on basis indication surgery (asymptomatic, 3.9%; asymptomatic but evidence enlargement, 4.9%; symptomatic, 7.2%) or urgency operation (elective operation, 4.5%; urgent 7.1%). Characteristics 72 participating surgeons did not influence rate. A family history AAA documented 6.1% cases more common if female = 0.03) less 65 years age 0.04). Patients without clinical coronary artery disease had a 0.8% from cardiac compared 6.2% any stigmata present. Prior aortocoronary bypass reduce incidence postoperative events having "routine" angiography have complicated course, fewer thrombotic complications, lower those it. Those an inflammatory (4.5%) significantly higher pain. Heparin administration (84.8%) complications graft thrombosis, "trash," distal and/or amputation. The 6.8% requiring suprarenal cross-clamping renal dysfunction 0.02) intraoperative blood loss 0.001), frequent. When time prolonged (more 70 minutes), requirement crystalloid fluid increased 0.001) myocardial infarction 0.004). After ligation left vein 7.9%, damage dialysis frequent 0.01). intra-abdominal (tube, 38.5% biiliac, 30.7%) wound infections thromboses femoral anastomosis. internal iliac flow interrupted bilaterally (12%), diarrhea ischemic colitis complications. Reimplantation inferior mesenteric carried out 4.8%. 2.1%, increased, transient 0.03).(ABSTRACT TRUNCATED AT 400 WORDS)
