Effect of supervised surgical training provided to general surgery residents on clinical maturation of arteriovenous fistula surgery: A retrospective cohort study.

Introduction: With the advent of endovascular technique and the emergence of vascular surgery as a separate branch distinct from general surgery, there is a decrease in exposure of open vascular technique to general surgery resident. Vascular access surgery is a vascular subspecialty area and not all residents get similar exposure during training, and this has implications if one becomes a vascular consultant in the future and have to undertake access surgery. There is no established protocol or duration, following which a surgical resident can be named as "trained" in vascular anastomosis.
