Abstract：discuss the influence of different respiratory phases on peak systolic velocity (PSV) of superior mesenteric artery (SMA). Methods The ultrosound data was retrospectively analyzed from the patients (n=24) with arcuteligment compression syndrome diagnosed by computed tomographic angiography (CTA) undergone ultrasonography in Xiaolan Hospital affiliated to Southern Medical University from July 2016 to Nov. 2018. The flow parameters including PSV of SMA on calm (PSVcalm), PSV of SMA on end inspiration (PSVinspir) and PSV of SMA on end expiration (PSVexpir) were recorded. Results The mean value of PSVcalm was (194±34) cm/s, mean value of PSVinspire was (155±26) cm/s and mean value of PSVexpir was (225±39) cm/s. The difference in PSV of SMA at different respiratory phases had statistical significance (all P<0.01). Conclusion There is significant difference in PSV of SMA at different respiratory phases, so the respiratory phase should be indicated when PSV of SMA is given ultrasonic detection.
