肠系膜血管病的超声诊断

目的 应用彩色多普勒超声诊断肠系膜血管病，并总结其声像图特征。方法 18例腹痛患者急诊行超声检查，应用高频探头测量小肠壁的厚度、病变范围、肠壁回声、肠蠕动状况、肠壁和肠系膜血流等。结果 肠系膜血管病18例中，超声诊断动脉性缺血14例，超声诊断符合率85．7％(12／14)；静脉性缺血4例，超声诊断符合率75．0％(3／4)。全部病例经手术证实，超声诊断符合率83．3％(15／18)，假阳性2例(11．1％)，假阴性1例(5．6％)。结论 超声检查可通过直接征象确定该病的诊断，并可判断肠系膜血管栓塞的类别、范围，是肠系膜血管病首选的检查方法。

Ultrasonographic diagnosis of mesenteric vascular diseases

Objective To investigate the diagnosis of mesenteric vascular diseases by two-dimensional ultrasonography and color Doppler flow imaging (CDFI) and to summarize ultrasonographic imaging features.Methods Eighteen patients were examined by ultrasonography in emergency.The thickness,scope and echo of the wall of the small intestine,the condition of intestinal peristalsis,the blood flow of the wall of the bowel and the mesentery were measured by ultrasonography.Results The diagnosis of all the cases was confirmed by operation.The accuracy rate of ultrasonographic examination was 83.3% (15/18).Two patients were pseudo-positive( 11.1% ) and one patient was pseudo-negative( 5.6% ).Conclusions The ultrasonographic examination with directimaging features can determine the diagnosis of the disease and assess the classification and scope of mesenteric vascular diseases,hence is the first choice and an indispensable method.
