[Ambulatory thrombectomy of a graft. Transcutaneous clamping]

Thrombectomy of a graft in ambulatory patients can be performed simply under local anesthesia, avoiding admission to hospital of patients with shunts. The technique is applicable to two types of shunt: arterio-arterial shunts for lower limb arteriopathy and arteriovenous shunts of a dialysis for chronic renal failure. The advantages are twofold: dissection of a subcutaneous graft is avoided and the patient can either immediately reinstitute activity if arteritic or dialysis for renal failure. The method is effective if the thrombus is of accidental origin, failures resulting from proximal or distal stenosis, their evaluation being possible during thrombectomy.
