Abstract

PURPOSE: This study was designed to evaluate the technical feasibility and clinical outcome of endovascular intervention using the retrograde transradial approach to treat dysfunctional hemodialysis shunts of the upper arms. MATERIALS AND METHODS: During the last 3 years, sixteen procedures were performed by the transradial approach in 13 patients with dysfunctional hemodialysis shunts of the upper arms. The radial artery was accessedwith the use of 20-gauge needle and a 6-Fr sheath. Angiography was performed using a 5-Fr catheter placed in the brachial artery, and then the interventional procedure was performed. The technical and clinical success rates, complications and patency rates were evaluated. RESULTS: Fistulography and percutaneous transluminal angioplasty via the transradial approach were performed in 16 cases of the 13 patients. Fistulography demonstrated stenosis in 7 cases and occlusions in 9 cases. Lesion multiplicity was identified in 9 out of 16 cases. Balloon angioplasty was performed in all cases and a stent was placed to overcome restenosis or to treat venous rupture in two cases. The technical success rate of balloon angioplasty was 87.5% (14/16) and the technical success rate with including stent insertion was 100%(16/16). The clinical success rate was 93.8%. There was one procedural-related complication. The primary patency rates at 6 and 12 months were 84.6% and 74%, respectively. CONCLUSION: The transradial approach seems to be technically feasible and effective for the management of insufficient hemodialysis shunts of the upper arms.
