Open vertical vein in non-obstructed supracardiac TAPVC: merits and fate

Data of 18 patients who underwent surgical repair of non-obstructed supracardiac total anomalous pulmonary venous connection between January 2007 and March 2011 were reviewed. The vertical vein was left patent in all patients as an elective surgical strategy. There was no operative mortality in patients with or without preoperative pulmonary infection, but there were significant differences in postoperative airway pressures, ventilation time, intensive care unit and hospital stay between the 2 groups. None of the patients demonstrated any flow in the vertical vein over a 30-day follow-up period. One patient had a mild anastomotic stricture and pulmonary venous hypoplasia. Operative repair of supracardiac total anomalous pulmonary venous connection can be carried out successfully without ligation of the vertical vein, and this strategy possibly reduces early postoperative morbidity and mortality, with no adverse effects detected in the short to midterm follow-up.
