In reviewing the literature, there was only one report having the ductus over 30 mm in width. Recently, we utilized cardiopulmonary bypass, hypothermia, and low flow through a transpulmonary approach to close 2 cases of giant patent ductus arteriosus. Both cases complicated with systemic pulmonary hypertension. Its outside diameters were 31 mm and 36 mm respectively based on the measurement from magnetic resonance imaging. To our knowledge, its seem the biggest ductus in comparison to previous reports. Both cases survived the operation and doing well for a follow-up time of 5 years and 4 years 10 months respectively.
在查阅文献时，仅有一篇报告提及动脉导管宽度超过30毫米。近期，我们采用体外循环、低温以及经肺动脉途径的低流量方法，成功闭合了2例巨大动脉导管未闭病例。这两例均合并有系统性肺动脉高压。根据磁共振成像测量，其外径分别为31毫米和36毫米。据我们所知，与既往报告相比，这似乎是最大的动脉导管。两例患者均手术成功，分别随访5年和4年10个月，情况良好。
