摘　　要：目的研究肺癌血供来源,为肺癌介入治疗提供理论依据。方法①对20例肺癌患者在介入治疗前分别作支气管动脉和肺动脉造影;②对32例肺癌患者作CT平扫和同层动态CT增强扫描,分别测量平扫、肺动脉期和主动脉期CT值变化;③对20例肺癌患者分别行支气管动脉CTA(CTBA)和经肺动脉CTA(CTPA);④对12例肺癌患者分别行支气管动脉和肺动脉多排螺旋CTA(MSCTBA,MSCTPA)。结果①20例肺癌均见支气管动脉供血,未见肺动脉供血;②全部肺癌肿块,肺动脉期CT值与平扫相同,主动脉期有明显强化;③20例CTBA全部见肿瘤血管,并全部强化,20例CTPA未见肿瘤血管也未见强化;④12例MSCTBA见明显血管供应肿瘤,22例MSCTPA均未见供血血管。结论多种方法证明肺癌血供来自体循环,不来自肺循环。Objective To study the blood supply of lung cancer,and thereby provide the theoretical basis for interventional therapy.Methods ①Bronchial arterial angiography and pulmonary arterial angiography were performed in 20 cases of lung cancer before interventional treatment.②Plain and dynamic contrast CT on the same level were performed in 32 cases of lung cancer,with measurement of the CT values before contrast and those of pulmonary arterial phase and aortic phase after contrast.③Trans-bronchial arterial CT angiography（CTBA）and trans-pulmonary arterial CT angiography（CTPA）were performed in 20 cases of lung cancer.④Trans-bronchial arterial multi-slice CT angiography（MSCTBA）and trans-pulmonary arterial multi-slice CT angiography（MSCTPA）were undertaken in 22 cases of lung cancer.Results ①Bronchial arterial supply instead of pulmonary arterial supply of lung cancer was demonstrated in all the 20 cases.②Of all the lung cancer foci,the CT values before contrast and those of pulmonary phase were similar,but increased significantly during aortic phase.③Tumor vessels and tumor enhancement were all revealed on CTBA,but none on CTPA,in all the 20 cases.④Distinct blood supply of tumor was shown on MSCTBA of 12 cases,but none on MSCTPA of 22 cases.Conclusions A serial research methods demonstrate that the blood supply of lung cancer originates from systemic circulation instead of pulmonary circulation.
