Abstract

Distal artery embolization is a well-known complication after mechanical thrombectomy, manifesting as limb ischemia. We describe a case of ischemia that developed after mechanical thrombectomy and stent placement in the venous anastomosis of a brachio- basilic arterio-venous graft. Subsequent investigations revealed that the stent had extrinsically compressed the adjacent brachial artery. Although balloon angioplasty of the artery initially restored flow, the patient needed surgical removal of the graft and stent to prevent persistent ischemia.
