Brachial Artery Flow Mediated Dilatation in Non-Alcoholic Fatty Liver Disease Patients by Vascular Ultrasound

Objective: To determine mean flow mediated dilatation (FMD) in brachial artery in patients withnon-alcoholic fatty liver disease. Study Design: Descriptive Cross Sectional study Place and Duration: It was conducted at Department of Radiology, Holy Family Hospital, Rawalpindi from 01-06-2014 to 31-11-2014 over a period of six months. Materials and Methods: A total of 100 patients were included in this study. Ultrasonographic examination of FMD was performed in the morning after an overnight fast and 15 minutes of rest in the supine position, using ultrasound scanner with a 10 MHz linear transducer. Normal range of FMD is known internationally as from 8 to 10. Results: The total numbers of patients were 100 with the mean age of 34.55 ± 6.59 years. 49 patients (49.0%) were male while 51 patients (51.0%) were female. Mean baseline brachial artery diameter (mm) was 3.84 ± 0.67 and mean flow mediated dilatation (FMD) was 6.52 ± 65. Conclusion: In conclusion, our study reveals that mean FMD in brachial artery in patients with non-alcoholic fatty liver disease is below normal range (6.25±0.65).
