Stent graft deployment in haemodialysis fistula: patency rates in partially thrombosed aneurysm and residual thrombi.

Background: Current evidence is insufficient to determine the contribution of stent grafts as treatment in partially thrombosed aneurysms or residual wall-adherent thrombi in arteriovenous fistulae (AVFs) for haemodialysis. The overall purpose of this study was to analyse patency rates of post-interventional covered stent deployment in those cases. We also assessed if patency rates differed when fistulas were punctured through the stent during dialysis sessions.

Patency rates of dysfunctional central hemodialysis venous catheter: Comparison between catheter exchange alone and catheter exchange with fibrin sheath angioplasty.

Purpose: The purpose of this study was to compare patency rates and risk of obstruction of catheter exchange (CE) with that of CE with fibrin sheath angioplasty (CE+FSA) in dysfunctional tunneled central hemodialysis venous catheter (CHVC).

Materials And Methods: A total of 107 consecutive patients with dysfunctional CHVC were retrospectively included. There were 66 men and 41 women with a mean age of 67.

Ultrasound-Guided Angioplasty of Dysfunctional Vascular Access for Haemodialysis. The Pros and Cons.

Purpose: To describe the benefits and the disadvantages of angioplasty in dialysis fistulas using only ultrasound guidance.

Materials And Methods: This is a prospective study in 132 failing or non-maturing arteriovenous accesses that underwent 189 ultrasound-guided balloon angioplasties. The technical success was defined as non-use of X-ray fluoroscopy during the procedure.
