Surgical treatment of anomalous right upper lobe pulmonary vein obstruction caused by compression between pulmonary artery and trachea: a case report.

Abstract

The normal anatomical course of right upper lobe pulmonary vein involves drainage anteriorly to the pulmonary artery, ultimately reaching the left atrium. However, anomalies can occur with the most common variation involving the convergence of the right upper lobe pulmonary vein with the superior vena cava. In a rare pulmonary vascular malformation, the anomalous right upper lobe pulmonary vein takes a path between the right pulmonary artery and right main bronchus [1]. During a clinical consultation, a patient presented in our hospital with this specific anomalous right upper lobe pulmonary vein, along with an atrial septal defect and a patent ductus arteriosus. As a consequence of this aberrant positioning, the right upper lobe pulmonary vein was compressed between the pulmonary artery and trachea, leading to pulmonary vein obstruction. Thus, a successful pulmonary vein replantation was performed to correct the congenital malformation.
