1986年以来,我们利用介入放射学技术,对于17例晚期不能手术切除直肠癌患者,采取肠系膜下动脉造影,大剂量化疗药物动脉内灌注化疗,然后经腹手术,用TH胶栓塞直肠上动脉,使直肠中上段肿瘤的主要供血血管发生永久性栓塞,造成肿瘤缺血、坏死与脱落,从而达到改善临床症状,延缓病人生命的目的。本文介绍了手术的设计及具体操作方法,并就此方法进行讨论及论证。 Since 1986, we have used interventional radiology techniques. We used 17 cases of advanced rectal cancer patients who were not able to have rectal cancer to undergo inferior mesenteric artery angiography. High-dose chemotherapy drugs were used for intra-arterial infusion chemotherapy, and then transabdominal surgery was used to embolize the upper rectal artery with TH glue. The main blood supply and blood vessels of the rectum in the upper segment of the tumor are permanently embolized, resulting in tumor ischemia, necrosis and shedding, so as to achieve the purpose of improving clinical symptoms and delaying the patient’s life. This article describes the design of the surgery and specific methods of operation, and discusses and demonstrates this method.
