A 60-year-old woman presented with a conglomerate pulmonary arteriovenous malformation (PAVM) size 8.2 × 7.2 cm on chest X-ray. Feeding arteries were A
a
7
and A
b
7
, A8, and A10. The diameter and length of the A
b
7
neck were 15.5 and 16 mm, respectively. After percutaneous transcatheter embolization of A8 and A10, PTE of A
a
7
and A
b
7
was conducted under balloon occlusion with interlocking detachable coils using a technique of dumbbell-shaped framing and filling, making a bridge from A
b
7
to the trunk of A9 and A10across A7. Follow-up computed tomography 10 months after treatment showed marked shrinkage of the PAVM.
