Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 1
Abstract
Introduction: The hilar structures of both the right and left lungs shows considerable variations. The aim of the present study is to understand the relative positions of the pulmonary artery, principal bronchus and pulmonary veins in the hilum of both right and left lungs. Methods: In the present study 39 lungs dissected from cadavers of both sexes were studied for the hilar structures and there relative positions from above downwards and before backwards with in the hilum. Results: The study has shown upper pulmonary vein, pulmonary artery and principal bronchus from before backwards in all the 35 lungs. In the 19 right lungs from above downwards the structures observed are as follows eparterial bronchus, pulmonary artery, principal bronchus and lower pulmonary vein. In the 16 left lungs from above downwards the structures observed are as follows pulmonary artery, principal bronchus and lower pulmonary vein. In all the 19 right lungs eparterial bronchus was accompanied in front by a branch of the pulmonary artery. Discussion: The detailed knowledge of the lung hilar structures and its possible variations is crucial for the cardio thoracic surgeons.
