| Objective To investigate the clinical value of efficacy evaluation and treatment guidance of color Doppler ultrasound in the treatment of those patients with superior mesenteric venous thrombosis (SMVT). Methods 12 patients with SMVT diagnosed in our hospital during Jan 2012 and Jan 2016 were selected, and such indicators as inner diameter and thrombosis echogenicity index of superior mesenteric vein (EIsmv), blood flow velocity and resistance index of superior mesenteric artery (SMA-Vmax & RIsmv), situation of surrounding small blood vessels, length of swelling intestine and volume of peritoneal fluid were detected by color Doppler ultrasound. All patients were divided into the improvement outcome group and the death outcome group based on their treatment outcomes, and other 12 healthy persons underwent physical examinations were enrolled simultaneously as the normal control group. Differences of indicators of color Doppler ultrasound between the two different outcome groups and the normal control group were analyzed. Results Ultrasound images of these SMVT patients showed bowel dilatation, local small bowel wall thickening, low SMVT echogenicity and no blood flow, and the initial diagnosis rate was 63.5%, the follow-up diagnosis rate was 100%. Among the 12 patients, 4 patients died and 8 patients improved after anti-thrombosis treatment. The SMA-Vmax and number of mesenteric vessels in the normal control group, improvement outcome group and death outcome group showed a gradual step-down trend, but the inner diameter of SMV, EIsmv, RIsmv, thickness of bowel wall, length of intestine and depth of ascites in them showed a gradual step-up trend, and all differences among the 3 groups were statistically significant (all P<0.05). Conclusion Continuously monitoring the treatment course of SMVT by color Doppler ultrasound could objectively evaluate the clinical therapeutic effects, and further guiding the clinical treatment. |
