Recurrence of Pulmonary Arteriovenous Malformation with Non-tuberculous Mycobacteria Infection Caused by Perfusion from the Pulmonary Artery and Bronchial Artery after Coil Embolization

Recurrence of an embolized pulmonary arteriovenous malformation (PAVM) is common after coil embolization. A 23-year-old woman who had undergone multiple instances of transcatheter coil embolization was admitted with hypoxia and hemoptysis. A PAVM in the left S6 was found to be recanalized by reperfu...

Description
Summary:Recurrence of an embolized pulmonary arteriovenous malformation (PAVM) is common after coil embolization. A 23-year-old woman who had undergone multiple instances of transcatheter coil embolization was admitted with hypoxia and hemoptysis. A PAVM in the left S6 was found to be recanalized by reperfusion through the pulmonary and bronchial arteries. The left S6 was partially resected; the specimen contained necrotic granulomas and non-tuberculous mycobacteria (NTM) around the PAVM. Clinicians should consider possible recurrence of PAVM after reperfusion of the pulmonary and bronchial arteries, as well as the risk of NTM infection during follow-up of patients who have undergone repeated coil embolization.
