Variations in Draining Patterns of Right Pulmonary Veins at the Hilum-An Anatomical study: A Case Report

Pulmonary veins carry oxygenated blood from the lungs to the left atrium. Variations are quite common in the pattern of drainage. The present study presents a case report of the incidence of different draining patterns of the right pulmonary veins at the hilum by dissecting the human fixed cadaveric lungs. Four separate ostia openings at the hilum of right lung were found. Clinically, pulmonary veins have been demonstrated to often play an important role in generating atrial fibrillation. Hence, it is important to look into the anatomy of the veins during magnetic resonance imaging and computerized tomography angiography.
