Amplatzer vascular plugs (AVPs) are among the embolic agents currently used for occlusion of pulmonary arteriovenous malformations (PAVMs). The authors encountered a patient with multiple PAVMs who developed spontaneous reperfusion of two PAVMs within 7 weeks of initially successful embolization with AVPs. Reperfused PAVMs were effectively occluded by coils deposited proximal to the vascular plugs. AVPs do not provide consistent long-term occlusion of the PAVMs. Deposition of coils proximal to the AVP may decrease the chance of PAVM reperfusion after the embolization.
