Transcatheter embolization of multiple bilateral pulmonary arteriovenous malformations in hereditary hemorrhagic telangiectasia

A 38-year-old woman with hereditary hemorrhagic telangiectasia (HHT) presented with exertional dyspnea and central cyanosis related to multiple bilateral pulmonary arteriovenous malformations (PAVM). Transcatheter embolization of the PAVMs resulted in resolution of systemic arterial desaturation and clinical symptoms. PAVMs in HHT can be effectively treated by transcatheter embolization even when bilateral and numerous.
