Abstract :Objectives: The aim of the study was to evaluate the effect of routine preoperative Doppler ultrasound mapping on surgical planning in patients having hemodialysis fistulas. Methods: Patients with arteriovenous fistulas insert ignore into journalissuearticles values(AVF); or arteriovenous grafts insert ignore into journalissuearticles values(AVG); were retrospectively reviewed between June 2010 and July 2017. Physical findings, preoperative Doppler ultrasound and postoperative findings of 1924 patients were reviewed. Results: Fistula maturation rate was 82%. The average duration of patency of the first fistula was 19 months insert ignore into journalissuearticles values(3-38 months); and the duration for a previous fistula operation history was 11 months insert ignore into journalissuearticles values(1-14 months);. Patency rate after 6 months was 78%. Mean maturation times for AVF and AVG were 70 and 28 days, respectively. Doppler ultrasound findings affected operation plans of surgeons in 227 of 908 insert ignore into journalissuearticles values(25%); first time fistula operation patients, and in 569 of 1016 insert ignore into journalissuearticles values(56%); patients with previous history of fistula surgery. Review of two groups revealed that Doppler ultrasound affected 41% insert ignore into journalissuearticles values(796/1924); of fistula planning of surgery for hemodialysis. Conclusions: We suggest that preoperative Doppler ultrasound should be routinely performed in patients undergoing fistulation for hemodialysis. Furthermore, a vascular radiologist and a vascular surgeon should decide the surgical plan together.
