Surgical treatment of juxta-renal abdominal aortic occlusion: report of 27 cases

Juxta-renal abdominal aortic occlusion is a relatively rare disease. We have treated 27 patients (25 males and 2 females) since 1984. Operations were performed on 25 patients, of whom 4 died and 84% improved. The main etiology was aorto-iliac stenosis or occlusion due to atherosclerosis and Takayasu's arteritis. Diagnostic basis included ischemia of lower limbs, pulselessness of abdominal aorta and both femoral arteries, sexual dysfunction, and positive result of angiography. Effective control of aorta below the left renal vein, aortotomy and retrograde endarterectomy were the main operative procedures. Axillo-bifemoral arterial bypass is recommended for patients associated with multiple diseases. The operative result is determined by associated diseases and the condition of run-off vessel. Associated diseases directly affect the mortality rate.
