Successful Pulmonary Artery Embolization for the Management of Hemoptysis in a Patient with Eisenmenger Syndrome Caused by Patent Ductus Arteriosus

Abstract

The patient was a 19-year-old woman who was diagnosed with patent ductus arteriosus complicating Eisenmenger syndrome at a previous medical institution. She was referred to our hospital and arranged for lung transplantation. She developed hemoptysis after the introduction of i.v. epoprostenol, which was administered as a bridging treatment while the patient awaited lung transplantation. She continued to suffer from recurrent hemoptysis, even after switching from i.v. epoprostenol to i.v. treprostinil. Angiography of the systemic and pulmonary arteries revealed the vessel responsible for the recurrent hemoptysis and pulmonary artery embolization was successfully performed. It is essential to identify the culprit vessel and physicians must not hesitate in performing embolization when patients develop lethal hemoptysis.
