Central venous catheter related Superior Vena Cava Syndrome after renal transplantation in two cases

Vena cava superior syndrome is a specific clinical disease; very important obstruction of the large central veins. Catheter-related deep vein thrombosis (DVT) and vena cava superior (VCS) syndrome are rare but serious complications that require specific care in these selected renal transplant recipient. Thrombosis formation, is a major complication of central venous catheter (CVC) attempts, however, arterial puncture, hematoma, and pneumothorax are more common complications. Mechanical complications of (CVC) have been reported in 5% to 19%. Incidences of CVC thrombosis have been reported in up to 66% of patients in venographic studies, however; VCS syndrome is a rare complication. After evaluating the catheter-related thrombosis risk, hemodialysis catheters were found to be the highest risk in comparison with other catheters. Catheter-related DVT and VCS syndrome are rare but serious complications require specific care in these renal transplant recipients. We report two cases of vena cava superior syndrome due to CVC thrombosis after kidney transplantation in two chronic renal disease patients with histories of previous catheter thrombosis.
