title: Common femoral endovenectomy in conjunction with iliac vein stenting to improve venous inflow in severe post-thrombotic obstruction.
abstract: Post-thrombotic syndrome secondary to iliofemoral deep venous thrombosis is a significant contributor to advanced chronic venous insufficiency. Iliac vein stenting is a standard procedure to treat iliocaval obstruction. In cases with obstruction extending across the groin, venous inflow for an iliac vein stent may be poor and compromise results of iliac vein stenting. Treatment options include extension of stents across the inguinal ligament that may have limitations in improving inflow only from only one vessel. Endovenectomy in this scenario becomes an attractive option with or without iliac vein stenting to provide outflow to the profunda vein, which otherwise is "axially transformed" in chronic iliofemoral deep venous thrombosis. We describe a technique of endovenectomy in combination with iliac vein stenting to establish a patent outflow tract for profunda and femoral veins. Accompanying also is a video demonstration of endovenectomy that will help viewers understand more technical aspects of the procedure.
