为避免胸膜腔穿刺损伤肋间血管 ,针对与之密切相关的肋间后动脉的主要分支进行仔细解剖并测量 ,为临床胸膜腔穿刺术提供解剖学依据。材料和方法选择 2 0例 40侧成人标本 (男女不限 ) ,均经1 0 %福尔马林固定 ,肉眼观察无明显的脊柱侧曲及血管变异。仔细解剖肋间后动脉的主要分 To avoid the damage of intercostal vessels by pleural puncture, the main branch of the intercostal artery closely related to it was carefully dissected and measured to provide anatomic basis for clinical pleural puncture. Materials and Methods 20 cases of 40 adult specimens (both male and female) were selected and fixed in 10% formalin. No obvious scoliosis and vascular variation were observed with the naked eye. Carefully dissect the main branch of the intercostal artery
