Abstract:
The authors describe two patients who underwent transfemoral endovascular procedures followed by the use of the Angio-seal arterial percutaneous closure device. In the first patient, distal migration of the device occurred with consequent occlusion of the ipsilateral popliteal artery 2 days post procedure. In the second patient, thrombotic occlusion of the femoral artery occurred and the patient presented with acute leg ischaemia 3 weeks post procedure. Surgical removal of the closure device with consequent revascularisation of the affected leg was achieved in both patients. This report aims to alert clinicians to the possibility of device-induced arterial occlusion, dislodgment and their sequelae.
