目的 评价DSA(DigitalSubtractionAngiography)对胃肠道疾病的诊断价值。 方法 回顾性分析均经手术病理证实的 40例胃肠道疾病的数字减影血管造影片 ,同时与钡餐、钡灌及内窥镜检查相对照。结果 血供丰富的病变有 :平滑肌肿瘤、腺癌、Crohn病与血管畸形 ,血管具有相应特征 ,结合钡餐、钡灌及内窥镜检查 ,临床诊断率较高。少血管病变有 :淋巴瘤、类癌及肠结核 ,缺乏明显的血管特征 ,介入诊断较难。平滑肌肿瘤血管呈“蜘蛛网”状 ,腺癌周血管增多、增粗 ,Crohn病病变肠管之间可见正常血管。血管畸形的血管增多、紊乱 ,钡灌及内窥镜检查多为阴性。结论 DSA对胃肠道疾病的诊断有一定帮助 ,尤其是对多血管肿瘤及血管畸形病变的诊断更有价值。
Objective To evaluate the diagnostic value of DSA (Digital Subtraction Angiography) in gastrointestinal diseases. Methods Retrospective analysis of 40 cases of gastrointestinal diseases confirmed by surgery and pathology digital subtraction angiography film, at the same time with barium meal, barium irrigation and endoscopy contrast. Results The rich blood supply of the lesions included: smooth muscle tumors, adenocarcinoma, Crohn’s disease and vascular malformations. The vessels had corresponding features. Combined with barium meal, barium irrigation and endoscopy, the clinical diagnosis rate was high. Less vascular lesions are: lymphoma, carcinoid and intestinal tuberculosis, the lack of significant vascular features, interventional diagnosis more difficult. Smooth muscle tumor blood vessels were “cobweb” -like, adenocarcinoma of the surrounding blood vessels increased, thickening, Crohn disease lesions between the normal bowel visible blood vessels. Vascular vascular malformations increased, disorders, barium irrigation and endoscopy were mostly negative. Conclusion DSA may be helpful in the diagnosis of gastrointestinal diseases, especially for the diagnosis of multi-vessel tumors and vascular malformations.
