目的探讨术前动脉造影对结直肠癌的诊断和治疗价值。方法３２例结直肠癌患者以Ｓｅｌｄｉｎｇｅｒ法行术前选择性动脉造影辅助诊断原发癌及肝转移癌，并行区域动脉灌注化疗。结果所有病例均无插管并发症。采用ＤＳＡ肿瘤定位３２例中３１例肿瘤血管显示清楚，与术后诊断符合率达１００％；门静脉显影同时辅助诊断肝转移癌。成功显象同时行区域动脉灌注化疗，６例结直肠癌合并梗阻行区域灌注化疗，５例得到改善，成功率８３３％，对无法切除的肿瘤可起到姑息治疗作用。结论术前选择性动脉造影有助于结直肠癌的定位诊断及发现肝转移癌，同时区域动脉灌注化疗，起到诊断和治疗的双重作用。为结直肠癌诊治提供了新的途径
Objective To investigate the value of preoperative angiography in the diagnosis and treatment of colorectal cancer. Methods Thirty-two patients with colorectal cancer underwent Seldinger preoperative selective angiography to assist in the diagnosis of primary and metastatic cancer, and regional arterial infusion chemotherapy. Results No intubation complications were found in all cases. Among the 32 cases with DSA tumor localization, 31 cases showed clear tumor vessels, and the rate of coincidence with postoperative diagnosis was 100%; portal vein imaging was also used to diagnose liver metastases. Successful imaging was performed simultaneously with regional arterial infusion chemotherapy, and 6 cases of colorectal cancer with obstruction were treated with regional infusion chemotherapy. Five cases were improved, and the success rate was 83. 3%. It can play a palliative treatment for unresectable tumors. Conclusion Preoperative selective angiography is helpful for the diagnosis of colorectal cancer and the detection of metastatic liver cancer. Regional arterial infusion chemotherapy also plays a dual role in diagnosis and treatment. Provides a new approach for the diagnosis and treatment of colorectal cancer
