A 60-year-old woman presented with a conglomerate pulmonary arteriovenous malformation (PAVM) size 8.2 Multiplication-Sign 7.2 cm on chest X-ray. Feeding arteries were A{sub a}{sup 7} and A{sub b}{sup 7}, A{sup 8}, and A{sup 10}. The diameter and length of the A{sub b}{sup 7} neck were 15.5 and 16 mm, respectively. After percutaneous transcatheter embolization of A{sup 8} and A{sup 10}, PTE of A{sub a}{sup 7} and A{sub b}{sup 7} was conducted under balloon occlusion with interlocking detachable coils using a technique of dumbbell-shaped framing and filling, making a bridge from A{sub b}{sup 7} to the trunk of A{sup 9} and A{sup 10}across A{sup 7}. Follow-up computed tomography 10 months after treatment showed marked shrinkage of the PAVM.
