[Prosthesis without puncture, 3d generation of vascular access for hemodialysis: a study of Hemasite in 10 patients].

Hemasite is a new vascular access for hemodialysis. The device has a carbon coated T-shaped body with a resealable silicon septum that obviates the need for skin punctures. It is implanted with attached PTFE grafts. Since August 1984, 10 Hemasite have been placed in 10 patients. After one year, 63% of Hemasite are still permeable: this success rate is at least similar to usual synthetic grafts. There is no infectious complication. The rate of thrombosis is high, but Hemasite offers the interesting facility to perform local infusion of thrombolytic drugs and/or painless angioplasty through its removable septum in case of venous stenosis. Patients and staff acceptance has been excellent.
