Endovascular Central Venous Stenosis Treatment Ended With Superior Vena Cava Perforation, Pericardial Tamponade, and Exitus

Venous hypertension and outflow stenosis of arteriovenous hemodialysis access managed using endovascular procedures usually present a high technical success rate, with few complications. We reported a rare and fatal complication of superior vena cava perforation with pericardial tamponade 3 months after subclavian vein stenting. Interventional recanalization with stenting for the management of superior vena cava syndrome or central vein stenosis is a safe procedure with a low complication rate. Stent misplacement, reocclusion, migration, or access-related complications appear to occur most frequently.
