左右肺水平裂形态观测

Observations on Lungs Horizontal Fissure

对１００例成人尸肺（左右共２００侧）进行直接观测，结果右肺不全水平裂６５例（占６５％），右肺中、上叶部分融合型的不典型三叶分型占多数，与一般资料相近。左肺完全性水平裂１１例（占１１％），不全性水平裂４９例（占４９％）；二者共计６０例（占６０％）。左肺外形分叶中，完全和不完全水平裂的存在及左肺的不典型三叶分型，在临床影像学检查中具有重要意义；在教学中。

Corpse Lungs were observed.The results showed that 65 cases of right Lobes were incomplete horizontal fissure(65%).11 cases of left lungs were complete horizontal fissure(11%) and 49 cases were incomplete extra horizontal fissure(49%).Therefore,the existence of horizontal fissure of left lung will not be ignored.When left lobes are lobulated,the existence of partly symphysic superior Lobe of singular segment,the existence of extra horizontal fissure and of the atypical trilobate lobe are significalnt in clinic and iconography.In teaching,it is essential to let students know the interior structures of lobes and distinct exterior lobes.
