  • Title: Pulmonary veins in total anomalous pulmonary venous connection with obstruction: demonstration using silicone rubber casts.
    Author: Seo JW, Lee HJ, Choi JY, Choi YH, Lee JR.
    Journal: Pediatr Pathol; 1991; 11(5):711-20. PubMed ID: 1745640.
    Abstract:
    We studied the postmortem vascular anatomy of four patients with total anomalous pulmonary venous connection (TAPVC) with obstruction using a silicone rubber casting method. Two patients were studied clinically but died before therapeutic intervention, one died after corrective surgery, and another was not diagnosed before death. The morphologic types were supracardiac (2), infracardiac (1), and mixed (1). One of the supracardiac forms had a stenosis at the left vertical vein by a bronchoarterial vise, and a collateral channel to the right superior caval vein was also present. In the other supracardiac case, a left upper pulmonary vein was connected to the left vertical vein above the stenotic portion, resulting in postoperative pulmonary hemorrhage into the left upper lobe. The patient with infracardiac TAPVC had a tree-shaped descending vertical vein and small opening at the inferior caval vein. In the mixed type, a right upper pulmonary vein ran between the pulmonary artery and bronchus draining into the superior caval vein, and the rest of the drainage was to the portal vein.
