Left Main Bronchus Compression Due to Main Pulmonary Artery Dilatation in Pulmonary Hypertension: Two Case Reports

Left main bronchus compression due to main pulmonary artery dilatation in pulmonary hypertension: two case reports.

Pulmonary arterial dilatation associated with pulmonary hypertension may result in significant compression of local structures. Left main coronary artery and left recurrent laryngeal nerve compression have been described. Tracheobronchial compression from pulmonary arterial dilatation is rare in adults, and there are no reports in the literature of its occurrence in idiopathic pulmonary arteria...

A Case of Extrinsic Compression of the Left Main Coronary Artery Secondary to Pulmonary Artery Dilatation

Extrinsic compression of the left main coronary artery (LMCA) secondary to pulmonary artery dilatation is a rare syndrome. Most cases of pulmonary artery hypertension but no atherosclerotic risk factors rarely undergo coronary angiography, and hence, diagnoses are seldom made and proper management is often delayed in these patients. We describe a patient that presented with pulmonary hypertensi...

Severe main bronchus obstruction due to pulmonary schwannoma: A Case Report

Pulmonary schwannoma is a rare neoplasm that arises from peripheral nerve sheath, Schwann cells, in the lungs and mostly remains asymptomatic for months. This report presents a seven-year-old female patient with an occasional cough and fever. She was hospitalized due to the lack of response to outpatient treatments, including antibiotics and antifebrile. A biopsy was taken from the mass by bron...

Left Main Pulmonary Artery

CONGENITAL ABSENCE of a main pulmonary artery branch is now a wellrecognized clinical entity, more than 60 cases having been reported in the literature. Diagnosis has heretofore been based primarily oln radiologic findings' in both routine x-rays and angiocardiography. Physiologic studies of pulmonary function, including differential bronchospirometry, however, provide valuable diagnostic infor...
