superficial venous position is deep puncture is feasible to transplant
arteriovenous fistula surgery. Is about to be buried in subcutaneous vascular
graft section, both ends are connected to Autogenous vein hemodialysis puncture
in the vascular graft can. The most common material is PTFE artificial blood
