title: Thrombosis caused by polyurethane double-lumen subclavian superior vena cava catheter and hemodialysis.
abstract: During an 18-month period, 82 consecutive patients (37 women and 45 men), with a mean age of 50 yr (range 15 to 74), underwent hemodialysis with 91 polyurethane double-lumen subclavian superior vena cava catheters inserted via the right subclavian vein. Upon catheter removal, venograms were performed in 53 which revealed thrombosis in 13. Autopsy performed in 13 other patients revealed thrombosis in three. Mean catheter duration was 27 days (range 1 to 138). Catheter duration was significantly (p less than .01) longer in the 16 cases complicated by thrombosis. There was no significant difference in the frequency of thrombosis between men and women. Two patients developed symptoms of subclavian vein occlusion after the creation of an arteriovenous fistula on the same side as a previous hemodialysis catheter. Overall, thrombosis was found in 23% and increased with longer catheter duration. We recommend phlebography to exclude thrombosis before creating an arteriovenous fistula on the same side as the previous hemodialysis catheter. There was no case of clinical discernible pulmonary embolism.
