Shunt lesions accompanying PLSVC-1. a, b Axial (a) and coronal-oblique reformatted (b) CT images indicate sinus venosus ASD (blue star) in a patient with PLSVC (red arrow) and accompanying abnormal right upper pulmonary venous drainage (blue arrows) to RSVC (green arrow). c Axial CT image depicts the ostium secundum ASD (blue circle) in a patient with PLSVC (red arrow). d, e Axial (d) and sagittal-oblique reformatted (e) CT images depict the accompanying PDA (blue arrows) in a patient with PLSVC (red arrow). PA represents the pulmonary artery, and Ao represents aorta. f, g Axial (f) and 3D VRT (g) CT images indicate the PAPVD to the RSVC (blue arrows) in a patient with double SVC (green and red arrows). h, i Coronal-oblique reformatted (h), and 3D VRT reconstructed (i) CT images indicate the PAPVD to the PLSVC (blue arrows) in a patient with double SVC (green and red arrows)
