摘要
目的 根据肺癌微循环的变化评价血管性介入的治疗效果。方法 138例原发性肺癌经供血动脉造影中 81例资料完整患者 ,测量肺癌治疗前后肿块染色的面积并进行比较 ,经统计学处理求P值。肿瘤染色为肺癌微循环的影象表现 ,由数字影象系统DSA取像。结果 1.本组肿瘤染色出现率为 84 .8% (117/ 138例 ) ;2 .资料完整的 81例肺癌肿瘤染色面积治疗前均值为 (94 1.4± 73.2 )mm2 ,治疗后为 (42 7.94± 93.8)mm2 ,P <0 .0 1。
Objective According to the changes of microcirculation in the pulmonary cancers, the treatment effect was evaluated after the vascular interventional therapy.Methods Angiography of 138 primary pulmonary carcinomas, and the feeding arteries were performed. Areas of mass blush were measured for 81 cases before and after therapy. The tumour blush was considered to be the imaging appearance of the microcirculation of the lung carcinoma. The angiographic images were collected by digital image system (DSA and movie). Results (1) The rate of the tumour blush appearance was 88.8% in this group. (2) The areas of the lung carcinoma blush in 81 cases before and after therapy were (941.4±73.2)mm 2 and (427.9± 93.8 )mm 2( P <0.01).Conclusions Interventional angiography for observing the cancer blush is one of the useful method to evaluate the microcirculation of the pulmonary carcinomas as well as their treatment effect.
