【摘要】Background Central venous thrombosis is a serious and life-threatening complication in hemodialysis (HD) patients with an indwelling catheter. The present study aimed to investigate the prevalence and characteristics of thrombosis of the superior vena cava and auxiliary branches in Chinese HD patients with an indwelling internal jugular venous catheter and to explore its risk factors.Methods Fifty-four patients on maintenance hemodialysis (MHD) with an indwelling catheter were enrolled in this cross-sectional study. The thrombosis of the internal jugular vein, subclavical vein, brachiocephalic vein and superior vena cava was assessed by vascular ultrasound. Collected were data on age, gender, ultrafiltration volume, Kt/V, blood pressure, levels of hemoglobin, serum albumin, lipid, calcium, and phosphorus, and parathyroid hormone.Results The patients were given short- or long-term double lumen central venous catheters. Among them, 42 patients had the catheter placed into the right internal jugular vein, and 12 patients into the left internal jugular vein. Different degrees
