Aim: Ultrasound (USG)-guided hemodialysis catheter placement is known to be superior to and more reliable than catheter insertion guided by anatomical landmarks. USG is used for vascular mapping (VM) before catheter placement, or real time. This study investigated the effect on outcomes of USG techniques used in patients with hemodialysis catheters inserted through the internal jugular vein (IJV) due to emergency hemodialysis indication while being monitored for Predialysis Renal Failure (PRF). Material and Methods: Fifty-nine patients with PRF undergoing USG-guided hemodialysis catheter placement between January 2012 and May 2014 at the Balikesir University Health Practice and Research Hospital were evaluated retrospectively. Results: Twenty-eight patients were male and 31 female. The right IJV was used in 57 patients and the left IJV in two. Success rate at first attempt in real time USG group was 91.3% (21/23), compared to 91.6% (34/36) in the VM group. Average number of puncture was similar (1.08±0.291 vs. 1.16±0.56). No complications occurred in either group. Discussion: Use of USG in real time and for VM in patients with PRF gives similar results in terms of success and complication rates. We therefore recommend that USG only for vascular mapping be used solely in these patients in order to avoid time loss and increased costs.
