Abstract

INTRODUCTION

The lungs are essential respiratory organs divided into lobes by the horizontal and oblique fissures. The hilum, located on the mediastinal surface of each lung, is where the bronchus, pulmonary veins, and pulmonary arteries enter and exit. This study aims to investigate and record the variations in the morphology of lung fissures, lobes, and hilar patterns observed in a South African sample.

METHODS AND MATERIALS

This cross-sectional observational study employed descriptive analysis. A total of 48 formalin-fixed bodies, comprising 24 females and 24 males from the Department of Human Biology at the University of Cape Town were studied were examined. Fissures were classified according to the Craig and Walker criteria.

RESULTS AND DISCUSSION

Incomplete oblique fissures were found in 25 right lungs and 30 left lungs. Incomplete horizontal fissures were observed in 39 right lungs, and one right lung exhibited the absence of both horizontal and oblique fissures. Accessory fissures were present in five right and seven left lungs. Variations in the hilar pattern were noted, including differences in the number and arrangement of structures in both right and left lungs.

CONCLUSION

Variations were observed in the lobes, fissures and the hilar patterns of several lungs. Awareness of these morphological variations is crucial for surgeons and radiologist to avoid misdiagnosis and complications during surgical procedures.

摘要

简介

肺是重要的呼吸器官，由水平和斜裂分为叶。肺门位于每个肺的纵隔面，支气管、肺静脉和肺动脉由此进出。本研究旨在调查和记录南非样本中观察到的肺裂、叶和肺门形态的变异。

方法和材料

这是一项横断面观察性研究，采用描述性分析。共检查了来自开普敦大学人类生物学系的 48 具福尔马林固定尸体，包括 24 名女性和 24 名男性。根据 Craig 和 Walker 的标准对裂进行分类。

结果与讨论

25 个右肺和 30 个左肺存在不完全性斜裂。39 个右肺存在不完全性水平裂，1 个右肺同时缺乏水平和斜裂。5 个右肺和 7 个左肺存在副裂。观察到肺门形态的变异，包括左右肺结构数量和排列的差异。

结论

多个肺的叶、裂和肺门形态存在变异。外科医生和放射科医生需要了解这些形态学变异，以避免手术过程中的误诊和并发症。
