Anatomical Study of Lobes and Fissures of Lungs and its Clinical Significance-A Cadaveric Study
Journal Title: International Journal of Anatomy Radiology and Surgery - Year 2019, Vol 8, Issue 1
Abstract
ABSTRACT Introduction: The human lungs are divided by fissures into lobes which permit movements of lobes to one another. The fissures act as barriers to avoid the spread of the diseases. Knowledge of variations in the lobes and fissures of the lungs is important for the Radiologists to interpret the radiological images and for the cardiothoracic surgeons to plan for segmental resection or lobectomy. Aim: To study the patterns of fissures and lobes of the lungs and their variations and to find their clinical implications and to compare with the previous studies. Materials and Methods: Forty pairs of lungs were used for the study. They were obtained from formalin fixed cadavers. The patterns of lobes, fissures and hilar anatomy of lungs and its variations were noted and specimens were photographed. Results: In the present study, incomplete horizontal fissure was found to be in 23(57.5%) right lung specimens and incomplete oblique fissure was observed in 20(50%) left lung specimens. Absence of horizontal fissure was about 10(25%) and oblique fissure was about six (15%) in right lung specimens. Absence of oblique fissure was about four (10%) in left lung specimens. According to Craig and Walker classification, Grade 1 and Grade 3 fissures were found to be more in both the lung specimens. Accessory fissure was observed in 5 (12.5%) specimens in the right lung and 10 (25%) specimens in the left lung. Single lobe was observed in both the lungs, 7.5% in the right lung and 5% in the left lung. Conclusion: Variations of fissures and lobes and of hilar anatomy is of great significance. Knowledge of these variations is important for Radiologists and Cardiothoracic surgeons for interpreting the data and to plan for the surgeries.
