Successful percutaneous aspiration thrombectomy for acute mesenteric ischemia in a patient with atrial fibrillation despite optimal anticoagulation therapy.

This report describes a case of acute mesenteric ischemia due to acute superior mesenteric artery (SMA) thromboembolism in a patient with chronic atrial fibrillation despite optimal anticoagulation therapy. The patient underwent SMA angiography and endovascular revascularization for acute mesenteric ischemia. We initially tried endovascular thrombolytic therapy for the thromboembolism of SMA, but it did not achieve complete revascularization. Therefore, we performed a percutaneous aspiration thrombectomy, which led to complete revascularization and successful treatment of acute mesenteric ischemia without any additional procedures.
