FIELD: vascular surgery.
SUBSTANCE: longitudinal venotomy is performed from the common femoral vein (CFV) with the transition to its bifurcation with exposure of the mouth of the deep vein of the femur and to the distal segment of the external iliac vein. Intraluminal synechiae and fibrous pathological substrate of the intimate layer are separated. Then, an autovenous fragment of the great saphenous vein is mobilized. The proximal segment of the autovenous fragment is cut longitudinally to a length equal to the length of the venotomy access of the CFV, and it is used as a patch to close the ventomic access with a continuous suture, forming a veno-venous anastomosis. After that, the free distal segment of the autovenous fragment is formed in the form of a half-loop and anastomosed with the femoral artery with an atraumatic thread, forming a temporary arteriovenous fistula (AVF).
EFFECT: method allows to optimize endovenectomy and deobliteration of the lumen of the vein with the formation of an AVF, as well as to prevent vein re-obstruction.
