摘　　要：目的:为右肺肺段切除术寻找肺段段间平面提供解剖学基础。方法:在48个成人右肺标本上,切开肺段间各表面形态处的脏胸膜,以寻找、分离其“自然分裂线”的方法,寻找段间平面。结果:①上叶尖前切迹、第1肋压迹和裂间嵴的出现率分别为91.7％,77.1％和93.8％,尖前切迹能被分离的占64.6％;②中叶“中副裂”的出现率为72.9％,能分离的占64.6％;③下叶“底内侧副裂”、“底前副裂”的出现率分别为60.4％和72.9％,“底前副裂”能分离的占62.5％。结论:尖前切迹、“中副裂”、“底前副裂”能分离出段间平面,是肺段分界的表面标志,可作为肺段切除术的手术入路。Objective: To provide anatomic basis for seeking for intersegmental plane of bronchopulmo-nary segments in segmentectomy of right lung. Methods: The visceral pleura of intersegmental surface in 48 adult right lung specimens were incised and intersegmental planes were identified by methods of search .separation for 'natural line of cleavage' in adjoining segments. Results: ①The occurrence rates of anterior a-pex notch,impression of first rib and interfissure crest were 91. 7%,77. 1% and 93. 8% respectively,and the separated rate of anterior apex notch was 64. 6%;②The occurrence rate of 'middle accessory fissure' in middle lobe was 72. 9% and of them the separated rate was 64. 6% ;③The occurrence rates of 'basal-medial accessory fissure' and 'basal-anterior accessory fissure' were 60. 4% and 72. 9% respectively,Separated rate of 'basal-anterior accessory fissure' was 62. 5%. Conclusion: Through separating anterior apex notch,'middle accessory fissure' and 'basal-anterior accessory fissure',could be shown and those intersegmental planes are the surface landmarks of bronchopulmonary segmental demarcation line and approaches of segmentectomy of lung.
