A retrospective statistical study on late blood pressure in patients operated for coarctation of the aorta have been done, in order to determine the optimum age for elective surgical treatment. Patients were considered hypertensive when their mean blood pressure exceeded the 90th percentile for their age and sex. The series included 126 isolated coarctation of the aortic isthmus operated at the CMC of the Porte de Choisy. The incidence of residual hypertension at rest in the series is as follows: age 1-5: 16,6 %;age 6-10: 34,3%; age 11-15: 47,5 %. In spite of these results there is no significative difference in the incidence by age group. A similar study by the Massachusetts General Hospital on 77 patients showed essentially the same results. A combination of both series (203 patients) which is possible because the study criteria are the same, gives the following results: age 1-5: 11,4 %;age 6-10: 31,9 %; age 11-20: 40,8 %. There is now a significative difference between age group 1-5 and the others (p Less Than 0,02).
the optimum age for elective correction of coarctation of the aorta is 1-5 year. The incidence of residual hypertension is only 11,4 % in that group (70 % confidence limits: 6 to 20%).
为确定选择性手术治疗的最佳年龄，对接受主动脉缩窄手术患者的晚期血压进行了一项回顾性统计研究。当患者的平均血压超过其年龄和性别的第90百分位数时，被视为高血压患者。该系列研究纳入了126例在舒瓦西堡中心医院接受主动脉峡部孤立性缩窄手术的患者。该系列研究中静息时残留高血压的发生率如下：1 - 5岁：16.6%；6 - 10岁：34.3%；11 - 15岁：47.5%。尽管有这些结果，但各年龄组的发生率无显著差异。麻省总医院对77例患者进行的类似研究结果基本相同。由于研究标准相同，将两个系列（203例患者）合并后得出以下结果：1 - 5岁：11.4%；6 - 10岁：31.9%；11 - 20岁：40.8%。现在1 - 5岁年龄组与其他年龄组之间存在显著差异（p小于0.02）。
主动脉缩窄选择性矫正的最佳年龄为1 - 5岁。该组残留高血压的发生率仅为11.4%（70%置信区间：6%至20%）。
