title: Acute occlusion of the abdominal aorta with concomitant internal iliac artery occlusion.
abstract: Acute aortic occlusion is a rare but catastrophic pathology with high mortality even after revascularization. We describe four patients who underwent thrombectomy or bypass surgery for acute aortic occlusion with concomitant internal iliac artery occlusion. Two patients (82- and 75-year-old men), who had insufficient reperfusion of bilateral internal iliac arteries after treatment (thrombectomy alone and axillobifemoral bypass, respectively), died on postoperative day three of uncontrollable hyperkalemia and multiple organ failure, respectively (mortality: 50%). The third patient (74-year-old man), in whom the left internal iliac artery was reperfused after an axillobifemoral bypass, underwent right lower limb amputation but survived. The fourth patient (63-year-old man) with sufficient internal iliac artery reperfusion bilaterally after aortobifemoral and right internal iliac artery reconstruction, had an uneventful postoperative course. Elevated creatine phosphokinase and myoglobinuria levels were observed in all four patients but were notably higher in the two patients with no reperfusion in either of the internal iliac arteries. Our results suggest that reperfusion of one or more internal iliac arteries may be a crucial factor in reducing mortality in revascularization treatment of acute aortic occlusion with concomitant internal iliac artery occlusion.
