Abstract
The LifeSite Hemodialysis System (Vasca, Inc., Tewksbury, MA, USA)is totally subcutaneous, incorporating two silicone catheters positioned in the central venous system and connected to a stainless steel-titanium valve implanted in a subcutaneous pocket.

Internal jugular vein placement with positioning of the valve on the anterior chest wall further improves results.
