32例胃癌术前腹腔动脉造影及灌注化疗并取同期单行手术治疗的24例胃癌对照.通过术前造影可大致了解肿瘤的部位、大小、数量及侵犯邻近器官的情况.符合率达62.5%～72.9%.经单次或多次腹腔动脉化疗后行手术治疗,术后观察其病理组织学的改变,发现不同程度的肿瘤细胞变性、水肿及坏死,大量的炎细胞浸润等.部分周围淋巴结亦见到坏死细胞,以化疗2～3次者更为显著.灌注药物以5～Fu,ADM,MMC.DDP为佳. 32 cases of gastric cancer patients undergoing celiac arterial angiography and perfusion chemotherapy were treated with single surgery at the same time. 24 cases of gastric cancer were treated by preoperative angiography. The incidence, size and number of tumors and invasion of adjacent organs could be roughly understood. The coincidence rate was 62.5%~ 72.9%. After single or multiple celiac artery chemotherapy followed by surgery, postoperative observation of histopathological changes, found varying degrees of tumor cell degeneration, edema and necrosis, a large number of inflammatory cell infiltration, etc. Some of the surrounding lymph nodes Seen necrotic cells, more significant 2 to 3 times of chemotherapy. Infusion of drugs to 5 ~ Fu, ADM, MMC.DDP better.
