Objective  To investigate the clinical effect and safety of balloon angioplasty (BAP) for patients with venous hypertension associated with autogenous arteriovenous fistula (AVF). Methods  Thirty-three patients with venous hypertension associated with AVF were hospitalized between August 2012 and August 2014 in the Department of Nephrology, West China Hospital of Sichuan University. All of the patients received BAP therapy. The clinical characteristics and therapeutic effects were comparatively summarized before and after operation. Results  Venous hypertension in all the 33 patients was caused by central venous stenosis or occlusion. Among them, there were 13 cases of stenosis on the site where the left innominate vein crossed the aorta, 10 cases of stenosis at the junction of the left innominate vein and superior vena cava, 4 cases of stenosis at the junction of the left subclavian vein and the innominate vein, 3 cases of right innominate vein stenosis, and 3 cases of innominate vein occlusion. The lesions were most common in the innominate vein. Innominate vein stenosis or occlusion occurred in 19 cases (57.6%), and stenosis at the junction of innominate vein and the superior vena cava or subclavian vein occurred in 14 cases (42.4%). Of the 33 patients, one patient with complete occlusion of the innominate vein did not receive BAP treatment because guide wire could not pass through the occlusion site. The other 32 patients underwent BAP treatment, among whom 30 (93.8%) were successful, and 2 (6.2%) failed. No obvious complications occurred. One day after BAP treatment, patients’ symptoms were significantly relieved. One to seven days later, swelling of the hands, pain, and other symptoms were relieved. In the 30 patients who underwent the treatment successfully, 29 were followed up for 3 to 24 months. Among them, 21 (72.4%) maintained clinical remission and the AVFs were functional, 6 patients (20.7%) got a restenosis later, and 2 patients died. Conclusions  BAP is effective and safe for venous hypertension associated with AVF. However, the follow-up of patients has displayed the possible risk of restenosis in long-term outcomes.
