Abstract

Background: Arteriovenous fistula (AVF) has been the preferred vascular access ‎in hemodialysis. Doppler ultrasonography is the main imaging modality of ‎hemodialysis arterio-venous (AV fistula). ‎
Aim: to study the role of Color Doppler Ultrasonography (CDUS) in assessment ‎of suspected complication of brachiocephalic fistulas in hemodialysis patients. ‎
Patients and methods: Prospective cross-sectional study carried out in the ‎Radiology Department at Al-Imamain Al-Kadhimain Medical city, between ‎November 2021 and November 2022. The study included 50 patients with end ‎stage kidney disease and had suspected non-functioning brachiocephalic fistula. ‎All patients were examined by using linear probe and occasionally curvilinear ‎probe. Color Doppler was done for assessment of associated brachiocephalic ‎arteriovenous fistula (BCAVF) complications. Doppler parameters in the arterial ‎and venous side, blood volume through the fistula, and the type of complication.‎
Results: the mean age of the patients was 43.8±12.2 with an age range of (27-68) ‎The fistula was functioning among 12 (24%) patients, functioning with ‎complication among 11 (22%) patients, and not functioning among 27 (54%) ‎patients. Regarding patients with adequate flow and associated complications 5 ‎‎(45.5%) had stenosis, and 6 (54.5%) had aneurysm in comparison of those with ‎fistula dysfunction where thrombosis is shown in 12 (44.44%), stenosis in 10 ‎‎(37.04%), aneurysm in 2 (7.41%) and steal syndrome in 3 (11.11%). ‎
Conclusions: CDUS is a good modality for evaluation of quantity and quality of ‎the AVF and detection of early and late complications. Stenosis and thrombosis ‎were the most common complications.‎
Key words: Ultrasonography, Brachiocephalic Fistulas, Hemodialysis.‎
