目的 探讨各段食管癌的血供 ,总结食管癌的DSA征象 ,寻找中晚期食管癌的最佳治疗方案。方法 筛选 75例已经X线钡餐或病理证实的食管癌病人 ,进行DSA检查和 1～ 3次以上的介入治疗。结果 各段食管癌的供血动脉不同 ,DSA的表现略有不同 ,对介入治疗效果亦有差异 ,鳞癌比腺癌好 ,农村病人比城镇病人效果好 ,尤其是首次效果更明显。结论 DSA对各段食管癌的诊断和转移情况的判断有定性作用 ,血管内介入治疗是中晚期食管癌的最佳治疗方案。
Objective To investigate the blood supply of esophageal cancer, summarize the signs of DSA in esophageal cancer and find out the best treatment for esophageal cancer in advanced stage. Methods Seventy-five patients with esophageal cancer who had been confirmed by X-ray barium meal or pathology were enrolled in this study. DSA and 1 ~ 3 interventional treatments were performed. Results The stages of esophageal cancer were different. The performance of DSA was slightly different. The effect of interventional therapy was also different. Squamous cell carcinoma was better than adenocarcinoma, and rural patients were more effective than the urban patients, especially for the first time. Conclusions DSA has a qualitative effect on the diagnosis and metastasis of esophageal cancer in all stages. Endovascular interventional therapy is the best treatment for advanced esophageal cancer.
