Acute Limb Ischemia Caused by Mural Thrombus from an Abdominal Aortic Aneurysm Treated with Thrombectomy and Endovascular Aneurysm Repair: A Case Report

Key Points

To report a case of acute limb ischemia caused by mural thrombus from an abdominal aortic aneurysm and its successful treatment.
Patient presented with acute limb ischemia due to irregular mural thrombi in an AAA.
Urgent thrombectomy was performed followed by elective endovascular aneurysm repair.
Computed tomography was used to assess the condition and guide treatment.
Successful reperfusion of the affected limb was achieved.
Endovascular aneurysm repair was completed without major complications.
Early intervention minimized the risk of mortality associated with acute limb ischemia.

Abstract

Acute limb ischemia (ALI) attributable to mural thrombus in an abdominal aortic aneurysm (AAA) is a clinically relevant complication owing to its high mortality risk. We encountered a patient with a floating thrombus in an AAA, which caused ALI. Computed tomography revealed an AAA with irregular mural thrombi, along with left popliteal artery occlusion. We performed urgent thrombectomy followed by elective endovascular aneurysm repair without any major complications. The keys to this successful outcome were earlier extremity reperfusion and less invasive aortic repair.
