[Hemorrhagic complication following an external shunt for hemodialysis: a clinical case and a proposed technical procedure for its prevention].

The vascular access for haemodialysis is still a problem not completely solved although surgical experience started more than thirty years ago. Particularly haemorrhagic complications can be dangerous because many patients go home after haemodialysis. The authors report a case in which the disconnection of the conic tip from the shunt cannula for haemodialysis induced an external bleeding, and propose a safety ligature. However, the latter is not necessary for a cannula integrated with the vessel tip.
