Abstract

Use of chronic intermittent hemodialysis is recent in Chad, where it remains underdeveloped. Vascular access is most commonly by catheter. The objective of our study was to demonstrate the feasibility of arteriovenous fistula (AVF) surgery for hemodialysis during deployments as part of the medical civic action program (MEDCAP). We prospectively included all patients admitted for AVF creation at Camp Kossei forward surgical unit in N'Djamena (Chad) between December 2016 and February 2017. Surgery was performed by an experienced vascular surgeon. The data collected included age, sex, cause of kidney failure, type of anesthesia, AVF location, and the duration of the intervention and hospitalization. Patients were examined one month after the procedure to evaluate the functionality, morbidity, and mortality of the AVF. We performed 17 AVF in 3 months. Male to female ratio was 3. High blood pressure was the main cause of chronic kidney failure (55%). All interventions were conducted under locoregional anesthesia. Overall, 35% of fistulae were radiocephalic, 41% brachiocephalic, and 24% brachiobasilic. The mean duration of intervention was 58 minutes and that of hospitalization one day. No deaths occurred. Global morbidity, including non-functioning AVF, was 25%. Our study showed that AVF surgery is feasible during deployment, especially in Chad, and meets the needs of the local healthcare facilities. It should be developed and taught to local surgeons.
