| Summary: | Knowledge of the position of lung fissures is necessary for the appreciation of lobar anatomy and thus locating the bronchopulmonary segments. The study aimed to investigate the patterns of fissures and lobes of the lungs and their variations in Andhra Pradesh, India and to find their clinical implications and compare them with the previous studies. Methods: The patterns of lobes, fissures, and hilar anatomy of lungs and its variations of 47 lungs by dissection method of embalmed cadavers was performed in the Department of Anatomy, Narayana Medical College (Nellore, India). The specimens were macroscopically observed for gross morphology of fissures and lobes. Results. The study showed oblique fissure in 33 % (grade 1), 26 % (grade 2), 24 % (grade 3) and 14 % (grade 4) of right lungs and 27 % (grade 1), 31 % (grade 2), 12 % (grade 3) and 12 % (grade 4) of left lungs. The incomplete horizontal fissure was seen in 38 % of right-sided lungs (grade 1). 19 % of right lungs and 10 % of left lungs had accessory lung fissures. Conclusions. Awareness of the variations in the lobes and fissures of the lungs is important for radiologists while interpreting magnetic resonance imaging and computed tomography scans. Also, we believe that the data from the present study certainly adds an important reference in the medical literature to thoracic surgeons in performing pneumonectomy and segmental resection. |
