Backgraund/Aim. Hemodialysis catheter, as an integral part of hemodialysis, is a catheter placed into the jugular, subclavian and femoral vein. The most common catheter-related complications are infections and thrombosis. The aim of the study was to analyze the prevalence of complications associated with differently inserted central-vein catheters for hemodialysis. Methods. The study was organized as a prospective examination during the period from December 2003 to November 2006, and included all patients who needed an active depuration by hemodialysis, hospitalized at the Clinical Center Kragujevac. The subject of the study were 464 central-vein catheters inserted during the mentioned period and there were recorded all complications related to the placement and usage of catheters. Results. The largest percent of inserted catheters was into the femoral vein - 403 (86.8%), significantly less into the jugular vein - 42 (9.2%), while into the subclavian vein there were placed only 19 catheters (4%). The average of femoral catheter functioning was 17 catheter days, in jugular catheters it was 17.3 days while the subclavian catheters had an average rate of functioning of 25.9 catheter days; there was found a statistically significant difference regarding the duration of functioning (p = 0.03). By microbe colonization of smear culture of the skin at the catheter insertion site, in clinically present suspicion of catheter infection, there was obtained a positive finding in 5.5% of catheters placed into the femoral vein and 7.1% of catheters instilled into the jugular vein, of which Staphylococcus aureus was the most important bacterial type, without statistically significant difference (p = 0.51). Haemoculture, done when there was a suspicion of bacteriemia, was positive in 3.7% of the patients with femoral and 4.8% with jugular catheters; Staphylococcus aureus was the most common bacteria type, but there was no statistically significant difference (p = 0.65). Colonizing the smears of the cut catheter tops, there was found a positive finding in 8.9% of femoral and 4.7% of jugular catheters in which the mentioned type of staphylococcal bacteria was prevalent, without statistically significant difference (p = 0.82). In 77% of femoral, 71.4% of jugular and 68.4% of subclavian catheters, there were no complications associated with insertion and manipulation of catheters for hemodialysis and the difference was at the limits of statistical significance (p = 0.06). Conclusion. Unconvincing rate of infections and a smaller percent of serious complications associated with the placement and use of central vein catheters instilled into the femoral vein, indicate that personal experience is sufficient recommendation to convince us that femoral vein does not represent a region with an increased risk for insertion of hemodialysis catheters.
