What is the primary purpose of endophlebectomy?

The primary purpose of endophlebectomy is to remove post-thrombotic residue from the venous lumen. This procedure is important in managing complications that arise from deep vein thrombosis (DVT), where fibrous clots and other materials may obstruct the vein's normal function. By clearing these obstructions, endophlebectomy helps restore the patency of the vein, thereby improving blood flow and alleviating symptoms associated with venous stasis and post-thrombotic syndrome. The removal of such residues can significantly reduce the risk of further complications and enhance the patient's overall venous health.

Other options involve different aspects of vascular assessment or treatment but do not address the core function of endophlebectomy, which is specifically aimed at clearing debris left in veins after a thrombotic event.
