ABSTRACT
Objective To observe the effectiveness of the percutaneous transluminal angioplasty (PTA) and percutaneous transluminal stenting (PTS) for central vein occlusion in maintenance hemodialysis patients.Methods From January 2010 to August 2015,a total of 42 patients with center vein occlusion of arteriovenous fistula were treated with maintenance hemodialysis,and the surgery and postoperative conditions,revascularization and improvement of vascular stenosis were observed.Results Among the 42 patients,38 cases were successfully carried out with PTA,and the patency rate was 90.5%(38/42).A total of 32 intravascular stents were placed in 30 patients whose vein stenosis were still greater than 30% after PTA.After surgery,the swelling of the patient receded rapidly and the internal fistula went back to normal.Conclusion PTA and PTS are effective methods for maintenance hemodialysis patients with central vein occlusion,and they could help protecting functional access in patients with autogenous fistulas with smaller wounds and faster effects.
