Do not blame the arterial catheter: A case report of intraoperative acute leriche syndrome

摘要

COMPLETE AORTIC OCCLUSION is rare but potentially catastrophic. Acute aortic occlusion carries an early mortality of 31% to 52% and is caused either by embolic occlusion of the infrarenal aorta at its bifurcation, known as a "saddle embolus," or by acute thrombosis of the abdominal aorta. Between 75% and 80% of cases of thrombotic aortic occlusion occur in the setting of underlying severe aortoiliac atherosclerotic occlusive disease, often precipitated by a low-flow state secondary to heart failure or dehydration. Intraoperative acute occlusion of the aorta (acute Leriche syndrome) during extracorporeal circulation is not common, and case reports regarding this are rare. Its detection early in the course of events is essential to prevent the catastrophe of losing the lower limbs because of ischemia.
