The native arteriovenous fistula (AVF) at the wrist [1] is generally accepted as the vascular access of choice in haemodialysis patients due to its low complication and high patency rates [2].
However, with an increasing number of elderly patients and patients with co-morbid conditions such as vascular disease and diabetes mellitus in the haemodialysis population, the creation and maintenance of a patent and well-functioning AVF has become a real challenge to nephrologists and vascular surgeons [3]. The DOQI guidelines state that creation of a primary AVF is possible in only 50% of the patients [4]. Therefore, in the US, synthetic polytetrafluoroethylene (PTFE) grafts are still the predominant form of permanent vascular access [5,6], despite the well known poorer outcome compared to AVFs [4,6,7].
To further increase the use of native AVFs, especially
