Endovascular Treatment of Concomitant Obstructions of a Denver Drainage Catheter and Superior Vena Cava in a Patient With Liver Cirrhosis.

With the increased use of intravascular catheters and devices, they have become the major non-malignant cause of superior vein cava (SVC) syndrome. We report a patient with liver cirrhosis who had received a peritoneovenous drainage catheter for refractory ascites, and then developed SVC syndrome because of concomitant occlusions of both the SVC and the drainage catheter. The patient regained patency of both the occluded vessel and the drainage catheter through percutaneous transluminal venoplasty, and there was dramatic improvement of clinical symptoms and good performance of the drainage catheter. Percutaneous intervention may be a feasible and effective therapy for SVC syndrome and intra-catheter thrombosis-related dysfunction.
