The arteriovenous fistula and the history of a forgotten pioneer.

OBJECTIVE

The radiocephalic arteriovenous fistula (AVF), first introduced by Dr Kenneth Charles Appell, allowed for the provision of hemodialysis for patients with chronic kidney disease (CKD) and remains a reliable method for vascular access today. The purpose of this study is to review the contributions that led to the development of the AVF. We describe the work of Dr Appell, whose procedure bypassed the need for repeated cannulation in achieving vascular access, transforming the management of patients with dialysis-dependent CKD.

METHODS

A literature search was conducted by searching "arteriovenous fistula," "history of surgery," "hemodialysis," "vascular access," "chronic kidney disease," "repeated cannulation," and "Kenneth Charles Appell" on PubMed, Embase, and Web of Science. Only articles written in English were considered.

RESULTS

Before the arteriovenous fistula, glass cannulae were used for vascular access, beginning with Abel's "vividiffusion" apparatus in animals and Haas's experimental dialysis on humans. The use of glass cannulae was continued by Kolff, who transitioned from venipuncture needles to glass cannulae. However, these attempts were complicated by thrombosis, excessive bleeding related to heparin use, and damage to vascular access sites from repeated cannulation. Arteriovenous shunts, using polytetrafluoroethylene tubing, were an improvement from previous attempts at vascular access, but were prone to local bleeding, shunt occlusion, phlebitis, cellulitis, and rarely lasted more than a few months. To address these challenges, Dr Appell created an upper extremity AVF, allowing for the provision of maintenance dialysis without externalized devices, repeated cannulation, and extensive anticoagulant administration. Despite Dr Appell's vision and pioneering contributions to vascular surgery, he has received little credit for his work.

CONCLUSIONS

The enormous contribution by Dr Appell in the development of the AVF that transformed the modern management of patients with CKD is recognized in this review of the history of vascular access surgery for hemodialysis.
