摘　　要：目的：探讨肠系膜血管CTA在小肠梗阻治疗中的价值。方法70例小肠梗阻患者按照治愈方式分为非手术治疗组、手术解除梗阻组（小肠缺血组）、手术切除梗死小肠组（小肠梗死组）,回顾性对比非手术治疗组和手术治疗组之间、小肠缺血组和小肠梗死组间的肠系膜血管 CTA 表现有无差异,包括肠壁强化减低、肠系膜浑浊、腹水和肠系膜血管形态异常。结果各种异常 CTA征象在非手术治疗组（33例）出现的几率均低于手术治疗组（37例）,2组间差异具有统计学意义（P 〈0.05）。在经手术治疗的37例中,肠系膜浑浊在小肠缺血组（25例）出现的几率显著低于小肠梗死组（12例）（P 〈0.05）,其他 CTA 征象的差异在2组间无统计学意义（P 〉0.05）。结论异常的肠系膜血管 CTA 表现对小肠梗阻的手术治疗具有提示价值,肠系膜浑浊征象提示可能需要手术切除梗死小肠。Objective To investigate the value of CT angiography （CTA）of mesenteric vasculature in the therapy of patients with small bowel obstruction （SBO）.Methods According to the cure way,70 patients with SBO were classified into nonoperative group, group of small bowel ischemia cured with surgery of removing obstruction,group of small bowel infarction cured with surgery of re-secting infarcted bowel.CTA findings of mesenteric vasculature including decreased enhancement of bowel wall,haziness of the mes-entery,ascites,and abnormality of mesenteric vasculature were retrospectively compared among nonoperative and operative group, group of ischemia and infarction,respectively.Results The incidence of all 4 CTA features in nonoperative group （n=33）were low-er than that in operative group （n=37）,and the difference was statistically significant.The incidence of haziness of the mesentery in group of ischemia （n=25）was statistically lower than that in group of infarction （n=12）,while the incidence of others CTA findings was not statistically significant between the two groups.Conclusion Abnormal CTA findings of mesenteric vasculature suggest the need for surgery in SBO patients,and haziness of the mesentery may predict the need for resection of infarcted bowel.
