摘　　要：目的评价多层螺旋CT血管成像(MSCTA)对肠道血管发育不良(AD)的诊断价值。资料与方法回顾性分析经临床和病理确诊的16例AD患者的MSCTA表现特征。结果16例AD中,局限型4例,弥漫型12例。发生于空肠3例,回肠2例,结肠11例,其中升结肠6例。局限型表现为局部肠道肠壁血管扩张增粗,弥漫型累及肠道血管扩张范围较广泛,肠管病变血管增多、增粗、聚集,动脉期静脉早显等。结论MSCTA可显示肠道AD的部位、范围、形态及影像特点,是评价AD十分有效的方法。Objective To evaluate the value of multi-slice CT angiography（MSCTA） in disgnosing intestinal angiodysplasia（AD）.Materials and Methods 16 patients with obscure gastrointestinal bleeding performed MSCT angiography examination.Clinical pathology and postoperative outcomes made the final diagnosis of angiodysplasia.Characteristics of MSCT angiography were analyzed retrospectively.Results 16 cases with angiodysplasia included limited type in 4 cases and diffuse type in 12cases.,Lesions located at jejunum in 3 cases,ileum in 2 cases,and colon in 11 cases（ascending colon in 6 cases）.The performance of the limited type angiodysplasia was local intestinal vascular dilatation.Diffuse type angiodysplasia showed more diffused and severe vascular dilatation in the involved intestines,and vein displayed ahead of schedule.Conclusion MSCT angiography shows the location,extent,patterns features of angiodysplasia,and has great value of angiodysplasia diagnosis.
