Balloon Angioplasty for Disruption of Tunneled Dialysis Catheter Fibrin Sheath

Abstract

Purpose

Management of failing tunneled hemodialysis catheters, sometimes the only vascular access for hemodialysis, presents a difficult problem. In spite of various techniques having been developed, no consensus has been reached about the preferred technique, associated with the longest catheter patency.

Methods

We report disruption of the fibrin sheath covering dysfunctional tunneled hemodialysis catheter by means of angioplasty, followed by over guidewire catheter exchange.

Results

Following the procedure, the catheter placed in the recovered lumen of the vessel presented correct function.

Conclusions

The described procedure allowed maintenance of vascular access in our patient. Additionally, dilatation of the concomitant central vein stenosis opens an option for another attempt for arteriovenous fistula creation.
