本文对经手术、病理证实的49例大肠癌的选择性血管造影的诊断价值及灌注化疗的效果进行分析探讨。本组大肠癌血管造影的主要表现为:①供血动脉增粗、扭曲;②瘤周血管受压移位;③血管受侵犯;④肿瘤血管;⑤肿瘤染色;⑥引流静脉增粗、扭曲;⑦造影潴留时间延长;⑧静脉早显。以血管受侵犯、肿瘤血管、肿瘤染色最具有诊断价值。根据造影显示的血管改变将大肠癌分为Ⅲ型:Ⅰ型为多血管型;Ⅱ型为少血管型;Ⅲ型为中间型,介于多、少血管型之间。认为多血管型及少血管型的大肠癌进行动脉灌注化疗疗效佳,而中间型行动脉灌注化疗无很大的临床意义。
This article analyzes the diagnostic value of selective angiography of 49 cases of colorectal cancer confirmed by surgery and pathology and the effect of infusion chemotherapy. The main manifestations of colorectal cancer angiography in this group are: 1 thickening and distortion of the supplying arteries; 2 displacement of blood vessels around the tumor; 3 invasion of blood vessels; 4 tumor blood vessels; 5 tumor staining; 6 drainage vein thickening and distortion; The angiographic retention time was prolonged; 8 veins appeared early. Vascular invasion, tumor blood vessels, and tumor staining are the most diagnostic values. According to the angiographic changes of the vascular manifestations of colorectal cancer is divided into type III: type I is a multi-vessel type; type II is a small vessel type; type III is an intermediate type, between the multi-and small vessel type. It is considered that the arterial infusion chemotherapy for multi-vessel type and small-vessel type of colorectal cancer has good curative effect, while the intermediate type arterial infusion chemotherapy has no great clinical significance.
