Vascular structures secondary to surgery. ac Axial CT images of the patient with the right aortic arch (RAA) and complex cardiac anomaly depict bicaval Glenn shunt (red arrows), which is an anastomosis constructed between the right and left SVCs and right and left pulmonary arteries (blue stars, c), respectively. After the performing surgical connection between the PLSVC and the left pulmonary artery, the PLSVC draining to the left pulmonary artery is called the Glenn shunt. e–f Axial CT images of the patient with the TOF show BT shunt (red arrows) connecting the left subclavian artery (red stars) and the left pulmonary artery (blue star). The distinction of PLSVC from the BT shunt is quite easy by establishing that the vascular structure in the left mediastinum (e) originates from the left subclavian artery and ends in the left pulmonary artery (f)
