摘要 目的:用选择性腹部血管造影的方法评估不明原因消化道出血的病因、造影表现,及介入治疗。方法:本组21例全部经手术病理证实,先前均经消化道钡餐造影、纤维内镜及纤维结肠镜检查,并分别行选择性肠系膜上动脉和肠系膜下动脉造影。9例行介入性治疗,采用血管收缩剂持续灌注和(或)栓塞。结果:21例出血的病因中,血管畸形7例,平滑肌瘤8例,溃疡性结肠炎4例,克隆氏病2例。血管造影表现以血管不同程度异常分布为主,其中血管畸形表现为动脉期肠壁静脉早期充盈及异常血管丛,肠壁内密度增高,静脉期仍见扩张迂曲之静脉;平滑肌瘤除显示丰富的肿瘤血管外,部分可见引流静脉提前显示;溃疡性结肠炎和克隆氏病表现为病变肠段细小网状血管分布。7例介入治疗后不再出血。结论:不明原因的消化道出血选用腹部血管造影,可以明确出血部位,出血原因,同时还可以直接进行药物灌注和(或)栓塞治疗。关键词 胃肠;出血;血管造影术;介入性
