OBJECTIVE: Venous hypertension due to subclavian or innominate vein stenosis coexisting with a functioning arteriovenous access in the ipsilateral arm is a complex problem in patients undergoing hemodialysis. Therapeutic solutions must optimally relieve symptoms, permit use of the angioaccess, and carry minimal surgical risk. The purpose of this study was to evaluate a simple surgical option, bypassing central venous obstruction to the great saphenous vein.
METHODS: Eight patients undergoing hemodialysis with severe symptoms and signs of venous hypertension due to subclavian or innominate vein obstruction and ipsilateral arteriovenous fistula or graft underwent axillosaphenous bypass via a subcutaneous 8-mm polytetrafluoroethylene bridge graft.
RESULTS: No intraoperative or immediate postoperative morbidity was observed. Early and 6-month patency rates were 100% and 87.5%, respectively. All patients reported improvement of symptoms, and the angioaccess was usable in all cases. Average follow-up was 21.5 months. One patient had a relapse at 5 months, which necessitated revision of the graft-saphenous vein anastomosis.
CONCLUSION: Bypassing a central vein occlusion to the saphenous vein relieves symptoms of venous hypertension and prolongs use of the hemodialysis angioaccess.
