During the same period, 16 cases of simple coarctation of the aorta repair, with end-to-end anastomosis through a left thoracotomy without partial CPB assistance, were included as the non-CPB group to evaluate the impact of partial CPB.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The median age and weight at surgery of the CPB group were 3.1 years (range, 9 days to 17.9 years) and 14.0 (range, 2.8\u201340.7) kg, respectively. Indications for the partial cardiopulmonary bypass with overlap were as follows: age\u2009&gt;\u20091 year (<jats:italic>n<\/jats:italic>\u2009=\u20097), mild aortic coarctation (<jats:italic>n<\/jats:italic>\u2009=\u20093), and predicted ischemic time\u2009&gt;\u200930\u00a0min (<jats:italic>n<\/jats:italic>\u2009=\u20095). Coarctation repair using autologous tissue was performed in seven cases and graft replacement in three. The mean partial cardiopulmonary bypass time, descending aortic clamp time, and cardiopulmonary bypass flow rate were 73\u2009\u00b1\u200937\u00a0min, 57\u2009\u00b1\u200927\u00a0min, and 1.6\u2009\u00b1\u20090.2\u00a0L\/min\/m<jats:sup>2<\/jats:sup>, respectively. Urine output during descending aortic clamping was observed in most cases in the CPB group (mean: 9.1\u2009\u00b1\u20097.9 mL\/kg\/h), and the total intraoperative urine output was 3.2\u2009\u00b1\u20092.7 mL\/kg\/h and 1.2\u2009\u00b1\u20091.5 mL\/kg\/h in the CPB and non-CPB group, respectively (<jats:italic>p<\/jats:italic>\u2009=\u20090.020). The median ventilation time was 1\u00a0day (range, 0\u201315), and the intensive care unit stay duration was 4 days (range, 1\u201316) with no surgical deaths. No major complications, including paraplegia or recurrent coarctation, occurred postoperatively during a median observation period of 8.1 (range, 3.4\u201317.5) years in the CPB group.
