Pulmonary Arterial Bypass Surgery for Fibrosing Mediastinitis Causing Severe Pulmonary Hypertension

Abstract

This case report describes a patient with mediastinal fibrosis. The mass lesion was expanding from the mediastinum to the cervical region and surrounding the major vascular structures. The patient had symptomatic dyspnea at rest and pulmonary hypertension secondary to stenosis of the bilateral main pulmonary arteries. To decrease pulmonary artery pressure and improve blood flow to the lungs, grafting from the pulmonary trunk to the bilateral interlobar pulmonary arteries was performed using cardiopulmonary bypass.
