Key result
Tunnelled hemodialysis catheter insertion into a persistent left superior vena cava achieves long-term functional success.
Why the study?
Persistent left superior vena cava is an uncommon venous system abnormality that is most commonly diagnosed incidentally during left-sided central vein catheterisation or pacemaker implantation.

Feasible in persistent left SVC; leaves open prospective safety data before wider use.
Case Report (n=1)
Tunnelled haemodialysis catheters can be successfully inserted and function well long-term in patients with persistent left superior vena cava.
Liberek et al. (2020) conducted a case report in Persistent left superior vena cava requiring haemodialysis (n=1). Tunnelled haemodialysis catheter insertion was evaluated on Catheter function. A 19-cm long tunnelled haemodialysis catheter was successfully inserted into a persistent left superior vena cava through the left internal jugular vein, demonstrating good long-term function.
