Thromboendarterectomy is a surgical procedure aimed at removing a thrombus, which can be a blood clot or atherosclerotic plaque, from the carotid, vertebral, or subclavian arteries. This procedure is performed through a neck incision, allowing direct access to the affected artery. The primary goal of thromboendarterectomy is to restore normal blood flow by eliminating obstructions that can lead to serious complications, such as stroke or transient ischemic attacks. During the procedure, the surgeon carefully isolates the thrombosed segment of the artery, ensuring that surrounding structures are preserved. A temporary shunt may be utilized to maintain cerebral perfusion while the artery is being repaired. The procedure involves meticulous dissection, removal of the arterial intima along with the thrombus, and subsequent reconstruction of the artery, which may include the use of a patch graft to enhance the diameter of the artery. This comprehensive approach not only addresses the immediate blockage but also aims to prevent future vascular complications.
