Why is using a light tourniquet recommended on the graft?
A light tourniquet will assist in palpating the graft making HeRO feel more like a standard graft. The rationale for using a light tourniquet is related to the lack of a venous anastomosis with HeRO. It is similar to using a tourniquet for a native fistula as there is also no venous anastomosis with a fistula.
