Antithrombotic Use Predicts Recanalization of Embolized Pulmonary  Arteriovenous Malformations in Hereditary Hemorrhagic Telangiectasia

Pulmonary arteriovenous malformations (PAVMs) are most commonly seen in association with hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome [1]. Standard treatment is coil embolization, as PAVMs can cause stroke and cerebral abscesses [2] due to a paradoxical shunt, and pulmonary complications such as spontaneous hemothorax and hemoptysis. PAVM recanalization is an important finding that may lead to paradoxical embolism. Previous studies [3,4] have demonstrated increased feeding artery diameter, low number of coils, use of oversized coils, and proximal coil placement within the feeding artery are associated with recanalization.
