ABSTRACT
Hemodialysis (HD) catheters are commonly used as temporary vascular access in patients with kidney failure who require immediate HD. The use of these catheters is limited by complications such as infections, thrombosis resulting in poor blood flow. We studied the complications and outcomes of nontunneled catheters used for vascular access in our dialysis unit. The records of all patients, with renal failure who were dialyzed over a two-year period and had a double lumen nontunneled catheter inserted, were retrieved. Catheter insertion was carried out under ultrasound guidance using the modified Seldinger technique. The demographic data of patients, etiology of chronic kidney disease, and complications and outcomes of these catheters were noted. Fifty-four patients with mean age 43.7 ± 15.8 years had 69 catheters inserted for a cumulative total of 4047 catheter-days. The mean catheter patency was 36.4 ± 37.2 days (range 1-173 days). Thrombosis occluding the catheters was the most common complication and occurred in 58% of catheters leading to catheter malfunction, followed by infections in18.8% of catheters. During follow-up, 30 (43.5%) catheters were removed, 14 (20.3%) due to catheter malfunction, eight (11.6%) due to infection, five (7.2%) elective removal, and three (4.3%) due to damage. Thrombotic occlusion of catheters was a major limiting factor to the survival of HD catheters. Improvement in catheter patency can be achieved with more potent lock solutions.
