Acute aortic thrombosis after intra-aortic balloon pumping.

Acute aortic occlusion is a rare but devastating complication of intra-aortic balloon pumping. Prompt diagnosis of aortic occlusion and immediate therapeutic decision making are keys for saving patients in such cases. We describe a 72-year-old man who underwent emergency surgical removal of a thrombus and aortoiliac bifurcated grafting for acute aortic occlusion after withdrawal of the intra-aortic balloon pumping catheter. The presence of a small unrecognized abdominal aortic aneurysm was considered to be the cause of thrombosis in this patient. Ultrasonographic screening for an abdominal aortic aneurysm is recommended for patients who require intra-aortic balloon pumping support.
