[Superior vena cava thrombosis in a patient on hemodialysis].

We present a patient with end-stage renal disease on maintenace hemodialysis through a permanent catheter (Permcath) on the right subclavian vein. One month after the catheter placement the patient exhibited a superior vena cava syndrome due to a pericatheter thrombosis. The patient was initially managed with anticoagulation with early clinical improvement. Nevertheless, the reappearance of the symptoms forced the removal of the catheter and percutaneous angioplasty of the superior vena cava. After those measures and anticoagulation with coumarin the patient remains stable with complete clinical resolution and angiographical improvement.
