Thromboendarterectomy is a surgical procedure specifically targeting the popliteal artery, which is the continuation of the femoral artery located behind the knee. This procedure is primarily performed to remove a thrombus, which can be a blood clot or atherosclerotic plaque that has adhered to the walls of the artery, leading to occlusion. The process involves the careful dissection of the thrombosed segment of the artery, allowing for the removal of both the thrombus and the affected vessel intima. By excising these obstructions, the procedure aims to restore normal blood flow through the artery. The surgical approach typically begins with an incision made over the knee to access the popliteal artery. Once the artery is isolated, clamps are applied to control blood flow, and an incision is made to facilitate the removal of the thrombus and plaque. The procedure may also involve the use of a patch graft, which can be harvested from the patient or sourced from a donor, or constructed from synthetic materials, to repair the artery after the obstruction has been cleared. This comprehensive approach not only addresses the immediate blockage but also aims to enhance the arterial lumen's diameter, thereby improving overall vascular health and function.
