B, C, Left pulmonary artery
angiograms show the AVM. D, Image after embolization
and after placement of an Amplatzer plug. E, A
selective angiogram of the second arterial blood supply to the AVM.
F, Angiogram after coil embolization.
G–K, Selective 1.5-mm
intravenous contrast-enhanced axial CT images show persistence of the
AVM 1 year later. L, M, Left pulmonary artery
angiograms show persistence. N, Selective catherization
of the artery supplying the AVM. O, Angiogram after
coil embolization of the AVM.
