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.

南非样本中肺裂、肺叶和肺门形态的变化。

简介肺是重要的呼吸器官，由横裂和斜裂分为肺叶。位于每个肺纵隔表面的肺门是支气管、肺静脉和肺动脉的出入口。本研究旨在调查和记录在南非样本中观察到的肺裂隙、肺叶和肺门形态的变化：这项横断面观察性研究采用了描述性分析方法。共研究了开普敦大学人类生物学系的 48 具福尔马林固定尸体，其中包括 24 名女性和 24 名男性。根据克雷格和沃克的标准对裂隙进行了分类：在 25 个右肺和 30 个左肺中发现了不完全斜裂。在 39 个右肺中观察到不完整的水平裂缝，1 个右肺既没有水平裂缝也没有斜裂缝。5个右肺和7个左肺存在附属裂隙。观察到肺门形态的变化，包括左右肺结构数量和排列的差异：结论：多个肺叶、肺裂和肺门形态均存在差异。对于外科医生和放射科医生来说，了解这些形态变化对于避免手术过程中的误诊和并发症至关重要。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
