Vascular access thrombosis lacks the implementation of a treatment algorithm at large scale, involving all the actors. We aimed to determine a better understanding of the current practice patterns around vascular access thrombosis in France, with 4 axes: incidence, surveillance protocol, treatment, and time to treatment. A comprehensive survey of all the nephrologists staffing all hemodialysis centers in France during April 2013 included 266 of 269 (99%) centers, treating 27,798 patients with arteriovenous fistula or graft. In 104 centers treating 11,088 patients, there were 905 documented episodes of vascular access thrombosis (8.8%) in 1 year; in the other 162 centers that supplied a range of events, the mean incidence was 8.4%. Use of in-line access flow monitoring as part of surveillance program was not correlated with better outcome compared with Doppler ultrasound (thrombosis: 7.9% vs. 10%, respectively, P = 0.09). Fifty-three percent of centers referred the patients to a vascular surgeon and 32% to an interventional radiologist (2% to urologist and 13% variable referral depending on the case complexity). Time to treatment was <24 hr in 58% and <48 hr in 91% of the centers; treatment >48 hr (9%) occurred mainly in rural zones (P = 0.04). The specialty of the treating physician did not influence time to treatment (P > 0.05). In France, vascular access thrombosis rate is low and not influenced by surveillance protocol type. Most patients can receive timely treatment by vascular surgeons or interventional radiologists.
