BACKGROUND/AIMS: The purpose of this study was to correlate blood flow velocity in the superior mesenteric artery and activity of ulcerative colitis.
METHODOLOGY: Doppler spectral analysis of superior mesenteric artery blood flow velocities were obtained in a blind study from 28 patients after fasting (A1: 13 patients with pancolitis, A2: 5 patients with subtotal colitis, B: 10 patients with left-sided colitis) and 50 healthy volunteers (control group). Disease activity was determined with clinical and endoscopic findings.
RESULTS: A significant increase in superior mesenteric artery blood flow measurements was observed in the active pancolitis group A1 [Vsyst = 3.64 +/- 0.18 m/sec and Vdiast = 0.94 +/- 0.09 m/sec as compared with healthy volunteers (Vsyst = 1.14 +/- 0.07 m/sec, Vdiast = 0.38 +/- 0.04 m/sec) P < 0.01. A minor increase in superior mesenteric artery blood flow velocity was observed in patients with subtotal colitis, group A2 (Vsyst = 2.06 +/- 0.14 m/sec, Vdiast = 0.45 +/- 0.05 m/sec) as compared with healthy volunteers P < 0.01. In group B with left sided colitis superior mesenteric artery velocity changes were not statistically significant (P > 0.05).
CONCLUSIONS: Doppler US velocity measurement of superior mesenteric artery may be used as an adjunct in the assessment of ulcerative colitis extension and activity.
