To determine prevalence of central vein stenosis following catheterization with double-lumen temporary catheters, we performed color Doppler sonography in 100 consecutive patients. We detected central vein stenosis in 18 cases; 11 patients in subclavian vein (SCV), 4 patients in internal jugular vein (IJV) and SCV, 2 patients in SCV and brachiocephalic vein, and 2 patients in IJV stenosis. There were statistical difference between groups with and without ste­nosis regarding time from discontinuation of catheters and use of aspirin (ASA). We could not find any statistical difference between these two groups regarding age, sex, duration of having chronic kidney disease (CKD), and duration of catheter remaining in place. We also found that there was a high proportion of stenosis in patients who still had catheter in their veins (15 from 44 patients, 34%) in comparison with patients who had already the catheters removed from their veins (3 from 56 patients, 5%). We conclude that stenosis of central veins can result from long indwelling time of central catheter used for hemodialysis. Aspirin may have a protective role against stenosis.
