ABSTRACT

We present a 67-year-old man who had undergone aortobifemoral synthetic graft surgery one year earlier. The patient experienced thrombosis of the graft nine months after the operation, and thrombectomy of the graft was planned. However, the patient refused to undergo repeat surgery for thrombus removal and was referred to our center for possible endovascular treatment. We treated the patient with percutaneous aspiration thrombectomy. The thrombi were chronic in nature but could be removed with minimal residue in any part of the graft by using repeated aspiration thrombectomy with 7 F guiding catheters. Underlying stenosis of both distal graft anastomoses was treated with percutaneous balloon angioplasty, and a self-expanding stent was deployed on the right distal anastomosis. A small fragment of thrombus embolized to the right popliteal artery and was removed with aspiration thrombectomy through a second antegrade puncture on the right side. We believe this is the first report of aspiration thrombectomy for an aortobifemoral graft thrombosis. The method was successful despite the chronic nature of the thrombi. Manual aspiration thrombectomy with largebore guiding catheters can be used as an effective recanalization method for delayed aortobifemoral graft occlusion and could be regarded as a good alternative technique to surgical thrombectomy in selected patients.
