Abstract

A patient with hereditary hemorrhagic telangiectasia and multiple bilateral pulmonary arteriovenous malformations (PAVMs) was found to have a complex PAVM in the left upper lobe with two feeder vessels, one of which could be successfully embolized with coils but the other of which was extremely short. Preservation of the parent vessel was considered important as it supplied a large portion of the left upper lobe. A covered stent was used to successfully exclude the feeding vessel and treat the PAVM. At 6-month follow-up, the PAVM sac was gone and the stent remained patent.
