Thromboendarterectomy is a surgical procedure specifically targeting the superficial femoral artery, which is a critical blood vessel located in the upper thigh. This procedure is primarily performed to remove obstructions such as thrombi, which are blood clots, or atherosclerotic plaques that have adhered to the inner walls of the artery. The presence of these obstructions can significantly impede blood flow, leading to various complications. During the procedure, an incision is made in the upper leg to access the affected artery. The surgeon carefully isolates the thrombosed segment of the superficial femoral artery, ensuring that surrounding structures are preserved. Clamps are then applied to the artery both above and below the obstruction to control blood flow during the operation. An incision is made into the artery, allowing for the removal of the thrombus and any associated plaque. This step involves separating the vessel lining from the arterial walls, which increases the diameter of the artery and facilitates improved blood flow. To secure the artery and prevent any separation of the vessel lining once blood flow resumes, sutures are used to attach the edges of the normal intima to the arterial walls. In some cases, a patch graft may be utilized to repair the artery, which can be sourced from the patient, a donor, or made from synthetic materials. Once the artery is successfully repaired, the clamps are removed, and the incision in the skin is closed, completing the procedure.
