ABSTRACT

Background: Lung is a vital organ of respiration, Knowledge of the variations in the position and number of fissures and lobes of the lungs is necessary for the appreciation of lobar anatomy and correlate these findings with clinical applications.

Material and Methods: The present study was performed on random lung specimens available at the museum of Human Anatomy and Embryology Department, Faculty of Medicine, Zagazig University, Egypt. A total of 40 lungs (21 right and 19 left) were studied for variations in the fissures, lobes and hilar pattern.

Results: Among the right-sided lungs, 24% presented with incomplete horizontal fissure, 10% with absence of the horizontal fissure, 19% with incomplete oblique fissure and 14% with accessory fissures.29% presented with 2 pulmonary arteries, 38% with 3 pulmonary veins and 24% with 3 bronchi in the hilum of right lungs. Among the left-sided lungs, 47% presented with incomplete oblique fissures, 5% with absence of the oblique fissure and 16% with accessory fissures. 16% of the left lungs showed 2 pulmonary arteries, 37% had 3 pulmonary veins in the hilum and 21% had 2 bronchi in the hilum.

Conclusion: The field of lung surgery is now highly advanced, with well developed radiological and endoscopic techniques. Hence, a proper understanding and knowledge of these morphological variations of lung fissures, lobes and the hilar pattern would be beneficial for surgeons, as well as for radiologists.

Key words: Lung, Lobe, Fissure, Hilum, Pulmonary.
