CTA与DSA对支气管肺癌的血供研究及其临床意义

目的 :探讨支气管肺癌的血供来源 ,为肺癌的营养学研究及介入治疗提供理论依据。材料和方法 :对 12例支气管肺癌 (中央型 5例 ,周围型 7例 )先分别行支气管动脉和肺动脉DSA ,再分别行两者的动脉造影CT(CTA)动态薄层扫描。结果 :DSA显示 12例癌肿全部由支气管动脉供血 ,未见肺动脉供血 ;而CTA示癌肿主要由支气管动脉供血 ,肺动脉亦参与供血 ,供血部位主要位于病灶周边部位 ,分布不均匀 ,周围型多于中央型。结论 :支气管肺癌 ,无论是中央型还是周围型 ,均由支气管动脉和肺动脉双重供血 ,其中支气管动脉为主要供血动脉 ;CTA较DSA结果更准确、可靠 ;介入治疗应兼顾两者

CTA and DSA Correlative Study on Blood Supply of Lung Cancer and Its Clinical Significance

Purpose: To study blood supplies of lung cancer in order to provide a theoretical basis for the nutriological study and interventional treatment of this disease. Materials and Methods: DSA and CTA of bronchial and pulmonary arteries were performed,respectively,in 12 patients with lung cancers(central type in 5 cases,and peripheral in 7 cases). Results: DSA showed that the lung cancers of all patients were supplied by bronchial arteries,and not by pulmonary arteries, but CTA showed that the pulmonary cancers were supplied mainly by bronchial arteries,and partly by pulmonary arteries(mainly the peripheral area of the cancer). The blood supply was not well distributed, which was more in the peripheral type than in the central type. Conclusion: Lung cancers,whether peripheral or central types,are supplied by both of bronchial artery and pulmonary artery; The bronchial artery is the main blood supplying one; The results of CTA are more accurate and reliable than those of DSA; Interventional treatment should take both bronchial and pulmonary arteries into conclusion.
