Özet
Background: Spontaneous echo contrast (SEC) is an ultrasonographic image of swirling blood flow resembling a dynamic, cigarette smoke-like image. It is mostly observed during the insertion of tunneled dialysis catheters (TDC) into internal jugular veins with ultrasound guidance, often different levels of SEC can be seen. The aim of this study is to investigate the impact of SEC detected during TDC insertion on the patency of the catheter. Methods: Patients who had a TDC insertion in our clinic between January 2015 and December 2020 were prospectively evaluated. The patients were grouped into five groups according to the sec level and followed. Results: A total of 226 patients were examined, among which 107 were male (47.3%). The mean age of all patients was 63.1 +/- 9.5 years. SEC grade and catheter occlusion was evaluated, it was observed that higher SEC grades were correlated with faster catheter thrombosis postinsertion. During the follow-up period, it was found that, compared to the SEC 0 group, catheter thrombosis occurred 3.22 times faster in the SEC 1 group, 2.66 times faster in the SEC 2 group, 5.80 times faster in the SEC 3 group, and 26.33 times faster in the SEC 4 group. (HR: 3.22, 2.66, 5.80, 26.33, respectively). Hematological parameters were evaluated by regression analysis, it was observed that hemoglobin, fibrinogen, and platelet count were not risk factors for SEC formation and SEC grade. Conclusion: Significant relationship was found between SEC grade detected during catheter insertion and catheter thrombosis in patients undergoing hemodialysis with a TDC.
