摘要
目的 观察大肠癌的血管造影表现以及在临床分期中的意义。方法 37例大肠癌病人在术前行DSA检查 ,分别选择肠系膜上、下动脉或二者同时造影 ,摄动脉期、实质期及静脉期照片 ,对采集的照片进行动态观察。结果 大肠癌血管造影有以下表现 :供应肿瘤的分支动脉增粗、扭曲 ,小分支增多 ,血管包绕肿瘤及供血动脉受侵蚀 ,新生肿瘤血管和肿瘤染色 ,静脉早显及静脉受侵 ,肿瘤外侵组织中见到浓集异常血管。结论 大肠癌血管造影有肿瘤浓染不规则 ,供血动脉受侵 ,静脉早显及受侵等特征性表现 ,肿瘤血管外侵是大肠癌的晚期表现。
Objective To observe the angiographic manifestation of the large intestine carcinoma and its significance in the clinical stage. Methods 37 patients with the large intestine carcinoma make the examination of DSA before operation. Selecting respectively angiography of superior mesenteric artery or inferior mensenteric artery or both them. Then taking films of arteria stages. parenchymal stages and venous stages. Doing dynamic observation to these films. Results The angioguaphy of the large intestine carcinoma have some followed manifestations. The tumor's branch arteries are coarse, kinking and have much more little branches. The blood vessels encyst the tumors,and the arteries which supply blood are eroded. Neonatal tumor blood vessels and tumor staining veins are developing early or eroded. In the tissue which the tumors erode could see abnormal blood vessels concentrating.Conclusion The angiography of the large intestine carcinoma have characteristic manifestation, such as tumors are stained irregularly. The arteries which supply blood are eroded. Veins are revealed early or eroded. [
