Percutaneous transluminal angioplasty in haemodialysis patients with central or peripheral venous stenosis

Dysfunction of arteriovenous fistulae (AVF), which result from peripheral or central venous occlusive illness, occurs very often in haemodialysis patients. In therapy, endovascular open procedures are prefered. Our study illustrated the clinical success of percutaneous transluminal angioplasty (PTA) for the treatment of these patient. A retrospective analysis was applied on patients presenting during a 2-years term with haemodialysis failure and ipsilateral arm swelling coherant with peripheral and/or central venous stenosis. PTA was performed as clinically and angiografically indicated. Technical success of PTA was defined less than 30% residual stenosis and clinical success was illustrated by resolution of pain and edema along with preservation of the AVF. Our study shows a subgroup of 26 patients that presented with symptomatic peripheral or central venous occlusive disease. Mean follow-up was 12.4 months (range, 3-24 months). PTA was successful in 26 patients 11 of whom were with central lesions and 15 of whom were with peripheral lesions. We were stated for central lesions PTA had a priority patency rates of 81.8%, 60%, 37.5% and supported primary patency rates of 90.9%, 70%, 62.5% at 3, 6, 12 months. For peripheral lesions, primary patency rates of 86.7%, 78.5%, 66.6% at 3, 6 and 12 months and assisted primary patency rates of 93.3%, 85.7% and 75%, separately. PTA for central and peripheral venous stenosis is be a successful and safe procedure in hemodialysis patients. In patients with lesions that are responsible for dilation, continuous functional access in the affected extremity is sustained, especially for patients with peripheral venous stenosis.
