Abstract

Purpose: To demonstrate the importance of venous vascular screening before the placement of tunneled and cuffed hemodialysis catheters in patients requiring hemodialysis prior to placement and/ or maturation of an arteriovenous fistula (AVF) or graft (AVG). Methods: Between October 1998 and March 2000, all patients requiring hemodialysis access placement were prospectively evaluated with duplex ultrasound for status of upper extremity vessels and central veins prior to selection of a permanent access site. When interim tunneled and cuffed hemodialysis catheters were required, they were placed on the side contralateral to proposed AVF/AVG placement. No catheters were placed without initial vascular screening. The study group was compared to historical controls during a similar period (April 1997 through September 1998) when no vascular screening was performed. Results: During the study period, 234 screening duplex ultrasound examinations were performed in 244 patients. Ten patients required no screening prior to access site placement. Overall, 353 catheters were placed, 243 (69%) on the right side and 110 (31%) on the left side. During the control period, 394 catheters were placed in 255 patients, 306 (78%) right-sided and 88 (22%) left-sided. The increase in left-sided catheters with ultrasound screening and careful planning for future access sites was significant (p<0.01). Conclusion: Vascular-screening-directed catheter placement significantly alters the side of catheter placement when compared to a management protocol without prior screening. Such screening helps identify the side of permanent access placement, while directing interim catheters to the contralateral side such that central veins may be preserved for permanent access.
