A Cadaveric Study of Anatomical Variation of Fissures of Lung
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 7
Abstract
Introduction: Lungs are essential organs of respiration. Variations in lobes and fissures of lungs are clinically significant. Knowledge of the position of fissures of the lungs is necessary for the appreciation of lobar anatomy and thus locating the bronchopulmonary segments. This study is conducted to observe the completeness of fissures, presence of accessory fissures. Materials and Methods: Present study was performed on 40 lungs (20 right and 20 left) from embalmed cadavers in department of anatomy, sms medical college, jaipur and lung specimens were examined for morphology of fissures and lobes, variations and find their clinical implications. Results: In my study the right lung was normal with complete oblique fissure in 88.5% and complete horizontal fissure in 70%. The left lung was normal with complete oblique fissure 75 %. In right lung, oblique fissure was incomplete in 10 % and horizontal fissure was incomplete in 20 % and absent in 10%. In left lung, oblique fissure was incomplete in15% specimen. Accessory fissures were present in 22.5% of right lungs and in12.5% of left lung and accessory lobes were present in 2 specimens (5%) of right lungs. Conclusion: There is a wide range of variation in occurrence of major, minor and accessory fissures in different populations. Knowledge of accessory fissure and variations in lobes and fissures of lung are important as such variations might explain variable presentation of certain clinical cases and also help the radiologist and clinician to make correct diagnosis, plan, execute and modify a surgical procedure. Knowledge of accessory fissure and variations in lobes and fissures of lung are important
