Transjugular percutaneous endovascular treatment of dysfunctional hemodialysis access

Abstract

Purpose: To evaluate the feasibility and the outcomes of transjugular percutaneous endovascular treatment of dysfunctional hemodialysis access in patients with chronic kidney disease. Methods: A total of 50 transjugular treatments in 38 patients with arteriovenous fistulas or arteriovenous grafts from September 2011 to May 2015 were included in this study. Medical records and angiographies were retrospectively reviewed. Success rate, patency rate, procedure time, and complications including internal jugular vein stenosis were evaluated. Results: A total of 50 sessions of transjugular treatments were performed in 38 patients. There were 31 native arteriovenous fistulas including 10 immature cases and 19 arteriovenous grafts. Among the 50 cases, technical success was achieved in 45 and clinical success was achieved in 44; 37 cases (74%) with multiple stenotic sites were treated by the transjugular approach without placement of cross-sheaths. The mean time from puncture of the internal jugular vein to first fistulography was 10 min, and the mean total procedure time was 64 min. The primary patency rate at 6 months was 77%, while the secondary patency rate at 6 months was 97%. Perforation occurred in two cases during conventional percutaneous transluminal angioplasty after failure of the transjugular approach. One dissection occurred during the transjugular approach. There was no newly developed internal jugular vein stenosis during a mean follow-up period of 19.3 months. Conclusion: For the treatment of dysfunctional or immature hemodialysis access, the transjugular approach is a feasible and effective option that avoids injury to the graft or draining vein, especially in immature fistulas.
