对手术切除的４７例直肠癌标本进行了血管灌注的造影研究。详细介绍了造影方法和结果。造影成功的关键在于标本的完整性、熟练的插管方法和摄片技术。造影结果表明，用灌注法显示微血管结构效果良好。肿瘤区最多见的血管改变为肿瘤新生血管、血管受侵像、肿瘤浓染和屈曲蛇行。直肠上动脉各级分支的变化较好地反映了癌肿的浸润深度。 Angiographic study of vascular perfusion was performed on 47 rectal cancer specimens. The imaging methods and results are described in detail. The key to successful angiography is the completeness of the specimens, skilled intubation methods, and radiography techniques. The angiographic results showed that the microvascular structure was well displayed by perfusion. The most common vascular changes in the tumor area were tumor neovascularization, vascular invasion, tumor hyperinfection and buckling. Changes in the branches of the upper rectal artery better reflect the depth of invasion of cancer.
