解剖观察120例成人胸部标本的第1～10肋间隙诸结构。肋间内、外肌移行为肋间内、外膜的部位不甚集中。胸横肌和肋间最内肌都恒定存在,但伸及范围有差异。肋间后动脉82.10%起自胸主动脉,单干起源者占77.49%,管径由上位者向下逐渐增粗。通过计算肋间神经的横断面积可见其粗细无一定规律。根据肋间血管神经束在肋间隙内的位置,认为胸腔穿刺或胸壁切口,以经下位肋骨上缘的稍上方为宜。
Anatomical observation of 120 cases of adult chest specimens 1 ~ 10 intercostal space structure. Intercostal, external muscle migration for the intercostal, adventitial parts of the less concentrated. Chest transverse and intercostal innermost muscles are constant, but there are differences in extensibility. The posterior intercostal artery 82.10% from the thoracic aorta, stemming from those who accounted for 77.49%, diameter from the upper down gradually thicken. By calculating the intercostal nerve cross-sectional area can be seen there is no certain thickness of the law. According to intercostal vascular bundle in the intercostal space position, that thoracentesis or chest wall incision to the lower edge of the upper edge of the ribs slightly above the appropriate.
