Key result
Ultrasound-guided hemodialysis catheter placement fails to prevent left-sided SVC misplacement, prompting CT diagnosis.
Why the study?
Hemodialysis central venous catheter insertion can be complicated by anomalous vessel anatomy, and catheters may become misplaced along anomalous routes despite ultrasound guidance.

Unexpected CVC position on imaging warrants consideration of persistent left SVC; this case extends the differential for malposition in hemodialysis access.
Case Report (n=1)
Highlights the importance of recognizing anomalous vessel anatomy, such as a persistent left superior vena cava, as a cause of central venous catheter malposition despite ultrasound guidance.
Santos et al. (2021) conducted a case report in Hemodialysis tunneled catheter malposition (n=1). Hemodialysis central venous catheter insertion was evaluated. A hemodialysis central venous catheter was misplaced into a left-sided superior vena cava despite ultrasound guidance, requiring a CT scan for diagnosis.
