A Cadaveric Study On Morphological Variations Of Lobar And Hilar Anatomy Of Human Lungs

ABSTRACT

Background: Knowledge of variations in fissures and hilar structures of the lungs is necessary for the appreciationof lobar anatomy and hilar anatomy of lungs.Materials and Methods: Morphological variations of fissures, lobar and hilar structures were studied in 50formalin fixed lungs belonged to 40-80 years age group.Results: In the present study following observation was made Right sided lungs had, Incomplete Horizontalfissures in 7 lungs, absent horizontal fissures in 2 lungs, among Hilar structures 2 arteries in 5 lungs, 3 veinsin 2 lungs, 1 bronchus in 2 lungs. Left sided lungs had, Incomplete horizontal fissures in 2 lungs, among hilarstructures, 1 vein in 2 lungs, 3 vein in 2 lungs and 2 bronchus in 7 lungs.Conclusion: Awareness regarding variations in fissures, lobes and hilar anatomy of the lungs is importantclinically while interpreting the radiological images as well as to plan various surgical procedures to avoidpostoperative complications.
