29例克罗恩病肠系膜血管造影表现

Angiography of 29 patients with Crohn's disease

目的 探讨克罗恩病患者肠系膜血管数字减影血管造影（digital subtraction angiography，DSA） 表现。 方法 收集2012年下半年在解放军总医院第一附属医院消化内科住院治疗的29 例确诊为克罗恩病患者临床资料，其中男性18 例，女性11 例。年龄18 - 55 岁，平均31 岁。与无病变者肠系膜动脉造影图形进行比较。 结果 29 例中，出现血管造影异常变化，主要有回结肠动脉扩张25 例（86.2%），血管分支增多且纡曲紊乱26 例（89.7%），毛细血管像可见肠壁浓染28 例（96.6%）。 结论 溃疡性结肠炎患者的病变区域血管会发生异常变化，数字减影血管造影可发现这些变化，为诊断治疗提供参考。

Objective To study the findings of digital subtraction angiography （DSA） in mesenteric artery of patients with Crohn’s disease （CD）. Methods Clinical data were collected from 29 CD patients （18 males and 11 females） at the age of 18-55 years （mean 31 years） with their diagnosis established in The First Affiliated Hospital of Chinese PLA General Hospital in the second half of 2012. Their general digital subtraction angiograms were compared with their vascular features, especially with the changes of their vascular lesions. Results Among the 29 patients with abnormal DSA, lleocolic artery was dilated in 25 （86.2%）, tortuous and disordered vascular branches were detected in 26 （89.7%）, and the intestinal wall was strongly stained at the capillary phase in 28 （96.6%）. Conclusion Abnormal changes occurred in vascular lesions of CD patients can be detected by DSA, which can provide reference for the diagnosis and treatment of CD.
