Left-sided obstructive lesions accompanying PLSVC. a–c Axial (a) and 3D VRT (b, c) CT images. The narrow segment compatible with aortic coarctation (blue arrows) is seen in a patient with PLSVC (red arrow) (a, b). Aortic coarctation treated by the endovascular intervention (blue circle) is depicted in another patient with double SVC (green and red arrows) (c). d–f Axial (d) and 3D VRT (e, f) CT images show the bicuspid aortic valve (blue arrows) (d) and the accompanying ascending aorta dilation (red stars) (e, f) in the patient with double SVC (green and red arrows). A bridging vein between RSVC and PLSVC (yellow arrows) is also seen (e, f)
