Perforation of the Superior Vena Cava by a Subclavian Hemodialysis Catheter: Early Detection by Angiography

A dual-lumen subclavian catheter was placed for temporary dialysis access in a 36-year-old woman. Clinical suspicion for a possible vena caval perforation by the catheter tip was confirmed by injection of contrast through the catheter. This technique allowed rapid diagnosis and prevented further potential complications related to catheter malposition.
