目的：通过食管动脉造影对胸段食管癌动脉血供进行研究， 为食管癌动脉灌注化疗提供依据。方法：７０ 例经病理证实的胸段食管癌病例，胸上段１７ 例，胸中段２９ 例，胸下段２４ 例，对肿瘤的供血动脉行选择性 Ｄ Ｓ Ａ 造影并进行了分析。结果： 胸上段肿瘤主要由支气管动脉发出食管支供血，胸中下段主要接受由支气管动脉食管支和食管固有动脉供血。肿瘤由２ 支或多支动脉供血者占９０ ％ ，单支供血者占１０ ％ 。各供血动脉间８５ ．．７ ％ 的病例存在广泛的交通吻合。结论： 胸段食管癌多支动脉供血居多，灌注化疗时靶血管选择的条数应由造影所显示肿瘤血管及染色范围确定。
Objective: To study the arterial blood supply of thoracic esophageal cancer by esophageal artery angiography, and provide evidence for the arterial infusion chemotherapy for esophageal cancer. Methods: 70 cases of thoracic esophageal carcinoma confirmed pathologically, 17 in the upper thoracic segment, 29 in the mid thoracic segment and 24 in the lower thoracic segment. The selective D S A angiography of the tumor artery was performed and analyzed. Results: The upper thoracic tumor was mainly from the bronchial artery to send blood to the esophagus. The middle and lower thoracic blood was mainly received from the bronchial arterial esophagus and the esophageal proper artery. Twenty-nine percent of tumors were fed by 2 or more arteries, and 10% were given by single donors. Between the feeding arteries 85 . . 7% of cases had extensive traffic anastomosis. Conclusion: Most of the thoracic esophageal cancer blood supply to the multi-artery, the number of target vessel selection during perfusion chemotherapy should be determined by the angiography showed tumor vascular and staining range.
