Initial and long-term outcomes of Percutaneous Transluminal Angioplasty for central venous stenosis or occlusion in chronic hemodialysis patients: Analysis of 363 lesions in single center

The purpose of this study was to evaluate the initial and long-term outcomes Percutaneous Transluminal Angioplasty (PTA) for central venous stenosis or occlusion in chronic hemodialysis patients. A total 363 lesions (277 86 occluded lesions) 146 patients were enrolled analyzed retrospectively; these included 130 de novo 233 restenosis lesions. procedural success rate our cohort 97.0% (352/363 lesions); significantly higher than that (99.3% vs. 89.5%, P < 0.001). Complications during PTA procedures occurred nine (2.5%); however, there no serious complications. 120 stents implanted 111 lesions; stent placement (68.8% 18.4%, The primary patency (P = 0.0004); assisted at 12 36 months 94.4% 89.0%, respectively. There significant difference between balloon angioplasty lesions, after 0.001). In conclusion, safe procedure with low technical failure. vascular access maintained by repeated intervention. Stent could help prolong period
