Congenital arteriovenous malformation (AVM) usually involves the head, extremities and internal organs, but isuncommon in the chest wall. It is, moreover, rarely combined with aneurysms. It can be cured by surgery, but isoften difficult to treat. The purpose of this study is to report a case of extensive AVM involving the rightlateral chest wall combined with multiple aneurysms, which was successfully treated by transcatheter embolizationusing several embolic materials.
