Atherosclerotic occlusion of the entire infrarenal abdominal aorta can produce gangrene, rest pain or claudication and can progress to involve the renal artery origins. Features of the operative technique for treating these juxtarenal aortic occlusions include self-retaining retraction, mobilization of the left renal vein with division of all non-renal branches, exposure of the suprarenal aorta and renal arteries by division between clamps of the surrounding paraaortic fibroareolar tissue and fat, sharp division of crural attachments to the aorta, control of the two renal arteries with doubled vessel loops and then direct vertical clamping of the suprarenal aorta. Through an arteriotomy below the renal arteries, 2-4 cm of pararenal aorta are cleared of thrombus and atherosclerotic debris under direct vision. After transfer of the suprarenal clamp to an infrarenal position, conventional aortobifemoral bypass is then performed. In a series of 18 patients with juxtarenal aortic occlusion managed by this technique, suprarenal clamp time ranged from 4 to 25 minutes (mean, 13 minutes). There was no morbidity from renal failure or emboli and no mortality. This technique allows for deliberate, careful disobliteration of the pararenal and infrarenal aorta and minimizes the risk of renal embolization.
