Percutaneous thrombectomy: a review.
Percutaneous thrombectomy (PT) is an established technique for the removal of acute thrombus in occluded arteries, veins and vascular grafts. Percutaneous thrombectomy can be used as an adjunctive treatment to other methods of thrombus removal such as thrombolysis or as sole therapy. The two main methods are percutaneous aspiration thrombectomy in which thrombus is removed by suction with the aid of wide-bore catheters, and mechanical thrombectomy using a variety of automated devices to fragment or remove thrombus. Aspiration thrombectomy is often used as an adjunct to thrombolysis in acute arterial occlusion, or as salvage therapy to remove distal emboli following iliac or femoropopliteal angioplasty. Mechanical thrombectomy is useful for the treatment of thrombosed dialysis grafts and is being increasingly used for the treatment of massive pulmonary emboli and ileofemoral or ileocaval deep venous thromboses.
