Abstract

Airway obstruction from an enlarged pulmonary artery (PA) is not a common occurrence. We present a rare case of respiratory failure secondary to right bronchus obstruction from a dilated right PA. A 54-year-old male with a known history of pulmonary hypertension (PH) and obstructive sleep apnea (OSA) presented with worsening dyspnea. He was found to have collapse of his right middle and lower lobes. Intubation was required for respiratory failure. To our knowledge, this is the first case to be reported in the literature where PH caused PA dilatation to such a degree as to cause bronchial obstruction and subsequent lobar collapse.
