Safety and efficacy of transcatheter embolization in patients with massive hemoptysis due to intercostal pulmonary venous shunts

Purpose Bronchial hemoptysis induced by intercostal pulmonary venous shunt (IPVS) is clinically rare. Pulmonary lesions on pleural surface may facilitate opening of vascular network. This retrospective study investigated safety and efficacy of embolization agents with small-particle embolization treating patients with massive hemoptysis due to IPVS.
