Catheter-related superior vena cava obstruction: A rare cause of chylothorax in maintenance hemodialysis patients

Abstract

With the extensive use of dialysis catheters in patients undergoing hemodialysis, superior vena cava (SVC) syndrome has gradually attracted attention in recent years. Chylothorax caused by SVC syndrome is rarely reported. In this paper, we report a case of chylothorax secondary to superior vena cava obstruction (SVCO) in a maintenance hemodialysis patient after multiple dialysis catheter placements. Relieving the SVCO through intravascular intervention could effectively treat chylothorax. In the past fourteen months, no recurrence of symptoms has been observed.
