Transvenous arterial repair

This operation is to repair the arterial fissure from the venous cavity to eliminate arteriovenous fistula and maintain access to the arterial lumen. The method is relatively simple, without the need to separate the tumor sac, which can avoid damage to collateral blood flow, often cure arteriovenous fistulas, rarely cause chronic ischemic signs of injured limbs, and for those with small fistula and sound arterial walls Is a very satisfactory method.
