Figure 2 Left side panels: A, C, E, G: angiograms at a subclavian artery showing stenosis (arrow) at the subclavian artery (A), stenosis (arrow) at anastomotic site of subclavian-to-graft (C), stenosis in graft (E) and graft-to-pulmonary artery stenosis (curved arrow) (G). There were shunt-related pulmonary artery stenoses noted on panels C and G (arrow). Right side panels: B, D, F, H (after angioplasty): repeat angiograms at the subclavian artery after angioplasty showing stenoses at the subclavian artery (arrow) (B), anastomotic sites (D and H) and graft (F) were relieved. There was dissection (white arrow) in the subclavian artery noted on panel D. The shunt-related pulmonary artery stenosis was partially relieved after a concurrent angioplasty using a larger size balloon (panel H).
