Fig 1 Helical computed tomographic angiography before (A), after the first (B), and after the second (C) operation. (A-1, B-1, and C-1) Differential color image from the posterior view. (Image of the descending aorta is eliminated in B-1.) (A-2) Selected image of anomalous venous channel. (B-2, C-2) Transverse section at the level of the pulmonary venous ostia (helical CT endoscopy). Severe stenosis at the vertical vein (A-1, A-2, star) and at the ostia of the pulmonary veins (B-1, B-2, star) is noted. This lesion is successfully repaired after the second operation (C-1, C-2, star). (Ao = aorta; INV = innominate vein; LA = left atrial; LPA = left pulmonary artery; LPV = left portal vein; RPA = right pulmonary artery; RPV = right pulmonary vein; VV = vertical vein.) Bars in A through C, 1.0 cm. The Annals of Thoracic Surgery 2001 71, 1690-1692DOI: (10.1016/S0003-4975(00)02314-6) Copyright © 2001 The Society of Thoracic Surgeons Terms and Conditions
