Prof. Gallieni and Dr Pasqui: is it time to rethink the hemodialysis catheter?

In this PVI 2026 interview, Prof. Maurizio Gallieni and Dr Edoardo Pasqui take a closer look at the arteriovenous segment and the challenges surrounding vascular access in haemodialysis patients. 

At the heart of their discussion is a device that has remained remarkably unchanged despite its central role in dialysis care: the central venous catheter. 

Prof. Gallieni explores why innovation has been limited and highlights the persistent challenges of infection, thrombosis, dysfunction and central venous injury, with the interaction between the catheter surface and blood remaining a major unmet need. 

The conversation also addresses the role of catheters in contemporary vascular-access strategies, questioning whether a device initially intended as a temporary solution is increasingly becoming definitive access for some patients. 

Looking ahead, Prof. Gallieni and Dr Pasqui discuss emerging technologies, the need for stronger long-term real-world evidence and the changes still needed to make vascular access safer and more durable.
