Figure 28:

Postoperative appearance of levotransposition of the great arteries after double-switch operation (Senning procedure and arterial switch) in an 8-year-old boy. (A) Coronal oblique maximum intensity projection (MIP) CT image and (B) coronal oblique cut volume-rendered image show the systemic venous limb of the baffle emptying systemic venous blood into the left atrium and morphologic right ventricle (long curved black arrows). There is evidence of severe stenosis in the systemic venous limb (red arrow). Also, note the right and left pulmonary arteries (short straight black arrows in B) lying on either side of the aorta as the normal postoperative appearance of LeCompte maneuver. (C) Axial MIP CT image and (D) axial cut volume-rendered images show the pulmonary venous limb of the baffle emptying pulmonary venous blood into the right atrium and morphologic left ventricle (long curved black arrow). Ao = aorta, IVC = inferior vena cava, LA = left atrium, LPA = left pulmonary artery, LV = left ventricle, PVL = pulmonary venous limb, RPA = right pulmonary artery, RA = right atrium, RV = right ventricle, SVC = superior vena cava, SVL = systemic venous limb.
