目的:为选择性支气管动脉造影提供解剖学依据。方法:选用40例肺血管灌注标本和8例肺腐蚀铸型标本进行观测。结果:40例成人肺标本中,共有59支支气管动脉,左肺1～3支,右肺为1～2支。支气管动脉分为3型,左肺2支型最多,右肺1支型最多。肺门支气管动脉平均外径,右肺1支型口径显著大于2支型,左肺各型口径无显著性差别。支气管动脉进入肺门后,一支动脉分布到几个肺叶者:左侧占72.7％,右侧占92.3％,专入某一肺叶者:左侧占27.3％,右侧占7.7％。肺叶支气管动脉和肺段支气管动脉均以2支最常见。结论:对于肺内支气管动脉的去向应引起重视。
Objective: To provide anatomic evidence for selective bronchial arteriography. Methods: 40 cases of pulmonary vascular perfusion specimens and 8 cases of pulmonary corrosion specimens were selected for observation. Results: Of the 40 adult lung specimens, 59 bronchial arteries, 1 to 3 left lungs and 1 to 2 right lungs. Bronchial artery is divided into 3 types, most of the left lung 2, 1 most type of right lung. The average diameter of hilar bronchial artery, right lung 1 branch diameter was significantly larger than 2 branches, the left lung diameter of no significant difference. Bronchial artery into the hilar, an artery distribution to several lobes were: left accounted for 72.7%, 92.3% on the right, specializing in a lobular were: the left accounted for 27.3%, the right accounted for 7.7%. Pulmonary lobes and bronchial arteries are the most common of the two branches. Conclusions: The fate of bronchial arteries in the lungs should be emphasized.
