Abstract
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) , A(8), and A(10). The diameter and length of the A(b)(7) neck were 15.5 and 16 mm, respectively. After percutaneous transcatheter embolization of A(8) and A(10), 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 A(9) and A(10)across A(7). Follow-up computed tomography 10 months after treatment showed marked shrinkage of the PAVM.
