PURPOSE
The aim was to study the anatomical variations of the arrangement of structures at the hilum of the lung.
METHODS
The present study examined the hila of 110 cadaveric lung specimens of south Indian population. The anatomical variations of the arrangement of structures at the hilum were macroscopically observed.
RESULTS
It was observed that the variations were higher in the left lung than in the right lung. The variations were observed in 16.1 % of right lungs and 48.2 % of the left lungs. There were some interesting anatomical variations like the two upper pulmonary veins, two pulmonary artery, two bronchi in the hilum of the left lung, three bronchi, four pulmonary veins and four bronchi. The present study was compared with a similar study from the same geographical location. It was observed that the frequency of variations and the hilar morphology of the arrangement of structures differ among the two separate studies from south India.
CONCLUSIONS
The observations of the present study suggest that the pulmonary hilar morphology is extremely variable.
目的
旨在研究肺门处结构排列的解剖变异。
方法
本研究检查了110例南印度人群尸体肺标本的肺门。宏观观察肺门处结构排列的解剖变异。
结果
观察到左肺的变异高于右肺。右肺变异率为16.1%，左肺为48.2%。左肺门存在一些有趣的解剖变异，如两条上肺静脉、两条肺动脉、两条支气管，还有三条支气管、四条肺静脉和四条支气管。本研究与同一地理位置的类似研究进行了比较。观察到来自南印度的两项独立研究中，变异频率和结构排列的肺门形态有所不同。
结论
本研究的观察结果表明肺门形态极具变异性。
