目的:统计支气管动脉解剖变异的类型,探讨支气管动脉解剖变异对肺部疾病介入诊断和介入治疗的临床意义。方法:对1995年～1999年期间所做的选择性支气管动脉造影、灌注化疗及栓塞的47例患者的临床资料进行回顾性分析,统计支气管动脉起源、开口水平、分支类型、共干情况及开口距脊柱中轴线的距离。结果:47例患者中,46例支气管动脉都开口于胸主动脉;1例患者的右支气管动脉起源于右锁骨下动脉。开口于T5～6水平右侧占86.6%,左侧占86.0%。支气管动脉干为1～3支,两侧支气管动脉为1～2支。支气管动脉开口位置在脊柱中轴线的左侧,距脊柱中轴线的距离左侧为3～4cm,右侧为1～2cm。结论:熟悉支气管动脉解剖变异的类型,有利于提高支气管动脉插管的成功率和肺部疾病介入治疗的治愈率,减少并发症的发生。
OBJECTIVE: To analyze the types of anatomical variations in bronchial arteries and to explore the clinical significance of anatomic variations of bronchial arteries in interventional diagnosis and interventional treatment of pulmonary diseases. Methods: The clinical data of 47 patients with selective bronchial arteriography, perfusion chemotherapy and embolization made during 1995-1999 were retrospectively analyzed. The origin, the level of the bronchial artery, the type of the branch, the total dryness and the opening The distance from the axis of the spine. RESULTS: Of the 47 patients, 46 had bronchial arteries opening in the thoracic aorta; 1 patient had a right bronchial artery originating in the right subclavian artery. Openings in the right side of T5 ~ 6 accounted for 86.6%, left accounted for 86.0%. Bronchial artery is 1 to 3, bilateral bronchial artery is 1 to 2. Bronchial artery opening position on the left axis of the spine, the distance from the spine axis left to 3 ~ 4cm, the right is 1 ~ 2cm. Conclusion: Familiar with the types of bronchial artery anatomical variations, is conducive to improving the success rate of bronchial artery intubation and lung disease intervention rate of cure and reduce the incidence of complications.
