Abstract: Objective To determine thrombosis distribution and risk factors of venous thrombosis following catheterization in patients with End-Stage Renal Disease (ESRD). Methods 127 HD patients have a history of right internal jugular catheterization were performed Computed Tomography Angiography (CTA), their clinical characteristics were examined. Patients were divided into thrombotic group and non-thrombotic group according imaging results and their clinical characteristics were compared between two groups, and the thrombosis anatomy positions of thrombotic group were measured. Result There were 66, 61patients in thrombotic group and non-thrombotic group, respectively. In thrombotic group, 43, 15, 4, 4 patients have there venous thrombosis in right internal jugular vein (RIJV), right innominate vein (RIV), right subclavian vein (RSCV) and superior vena cava (SVC),respectively. There were significant difference between CVS group and non-CVS group in catheter days, low-density lipoprotein cholesterol levels, total cholesterol levels; there were no significant difference between two groups in age, gender, hemoglobin levels, albumin levels, catheterization numbers, total cholesterol, triglyceride. Conclusion The most often anatomic locations of venous formation following right internal jugular venous catheterization in patients with ESRD were RIJV, RIV, RSCV and SVC, respectively, to decrease catheters days, low-density lipoprotein cholesterol levels, total cholesterol levels may be useful for reducing occurrence of CVS.
