Emergent Lung Resection for Massive Hemoptysis From Bronchial Malformation.

Bronchial arteriovenous malformations are usually asymptomatic findings noted on imaging but may present with massive hemoptysis after endobronchial rupture. Initial treatment usually involves transcatheter embolization with surgery reserved for refractory cases. Here, we present a patient with large-volume hemoptysis after bronchial arteriovenous malformation rupture. Attempted endovascular management was unsuccessful owing to unfavorable anatomy and hemodynamic instability, necessitating emergent use of extracorporeal membrane oxygenation followed by right bilobectomy.
