肺癌的血供主要来源于支气管动脉已无可争议，但肺动脉是否参与血供则很少报道。有人认为肺动脉不参与肺癌的供血，肺癌的介入治疗只经支气管动脉进行。为了进一步确定肺动脉是否参与肺癌的供血，自1996年6月至1997年10月我们对35例肺癌患者在经支气管动脉介人治疗前均行肺动脉
It is no doubt that the blood supply of lung cancer is mainly derived from bronchial arteries, but it is rarely reported whether pulmonary arteries participate in blood supply. Some people think that pulmonary artery is not involved in the blood supply of lung cancer, and interventional treatment of lung cancer is only performed through the bronchial artery. In order to further determine whether the pulmonary arteries are involved in the supply of lung cancer, from June 1996 to October 1997, we conducted pulmonary arteries in 35 patients with lung cancer before treatment with bronchial arteries.
