Abstract

Central venous disease is a serious complication in patients undergoing hemodialysis, often presenting with symptoms of venous hypertension. Treatment is aimed to provide symptomatic relief and to maintain hemodialysis access site patency. Aim: To describe our experience in the endovascular treatment of central venous stenosis or obstruction in patients undergoing hemodialysis. Settings and Design: This was a retrospective study carried out in a tertiary care center. Study duration was 36 months. Follow up was variable. Materials and Methods: Fifty six patients of chronic renal failure undergoing hemodialysis presented with central vein stenosis or obstruction having ipsilateral vascular access, between January 2018 and December 2021. All the patients underwent endovascular treatment and were analyzed retrospectively. Results and Conclusion: A total of 56 patients (48 male and 8 female) underwent 72 interventions for 52 stenotic segments during a time period of 3 years. Forty stenotic segments were in brachiocephalic vein, sixteen in subclavian vein. The technical success rate for endovascular treatment was 71.4%. All underwent percutaneous transluminal angioplasty (PTA) alone and Sixteen presented with restenosis later. Repeat Balloon angioplasty was done in Sixteen patients, Eight of which required >=2 reinterventions during follow up. We found endovascular treatment safe and effective in treating central venous disease
