case_images: CT angiography at diagnosis of pulmonary vein stenosis. (a, d) Total occlusion of LSPV. (b, e) Stenosis of LIPV. (c) Total occlusion of RSPV in segment 3. (f) Stenosis of RIPV. CT, computed tomography; LIPV, left inferior pulmonary vein; LSPV, left superior pulmonary vein; RIPV, right inferior pulmonary vein; RSPV, right superior pulmonary vein.

case_images: The left superior PV (LSPV) and segmental branch of the right superior PV were totally occluded, and the inferior PVs presented with stenosis (Figure 1).
case_images: CT angiography at follow-up examination 4 months after the clinical course. (a, d) Successful stenting of LSPV. (b, e) Successful stenting of LIPV. (c, f) Successful balloon dilatation of RIPV. CT, computed tomography; LIPV, left inferior pulmonary vein; LSPV, left superior pulmonary vein; RIPV, right inferior pulmonary vein.

case_images: Since PV dilatation and stenting of LSPV and left inferior PV, as well as balloon dilatation of RIPV, was performed successfully (Figure 2), the intervention of the right superior segmental PV failed.
