选择性肠系膜上动脉造影在小肠肿瘤诊断中的作用

The diagnosis of small intestinal tumor with selective superior mesentary angiography

１４例诊断困难的小肠肿瘤患者经选择性肠系膜上动脉造影检查作出诊断，并经术后病理证实。其中７例因消化道大出血急诊造影。造影结果显示血运丰富型肿瘤１０例，包括平滑肌瘤６例、平滑肌肉瘤３例、错构瘤１例；少血管型肿瘤２例：低分化腺癌１例、乳头状腺癌１例；血管畸形２例：均为血管瘤。对诊断困难的消化道出血，选择性肠系膜上动脉造影可作为常规检查方法。

There were 14 cases of small intestinal tumor diagnosed by selective superiormesentary angiography and all were proved by post-operative pathology reports. Of which theangiography was done in 7 cases with emergency massive GI bleeding. Angiograms showed thetumor were hypervascular in 10 cases, including leio-myoma 6.leiomyo-sarcoma 3.hamartoma 1;hypervascular in 2; poorly differentiated adenocarcinoma 1. papilloadenocarcinoma 1, andmalformation in 2 with hemangioma. Selective superior mesentery angiography might beperformed as a routine examination method in the difficult diagnosis of gastro-intestinalhemorrhage.
