The necessity of closing a hemodynamically significant patent ductus arteriosus (PDA) in a premature neonate is unequivocal. Until 12/86 the PDA was disected and ligated and a chest tube was inserted (127 pts.) Since 1/87 45 pts. (weight less than 1500 g) underwent PDA-closure using a metal-clip and no chest tube. Simplified surgical technique in closure of PDA in the premature neonate has led to a marked reduction of operating time (mean from 36 to 18 min) and has decreased the incidence of perioperative complications.
在早产新生儿中闭合具有血流动力学意义的动脉导管未闭（PDA）的必要性是明确的。直到1986年12月，对PDA进行解剖和结扎，并插入胸管（127例）。自1987年1月以来，45例（体重小于1500克）使用金属夹闭合PDA且未插胸管。早产新生儿PDA闭合手术技术的简化显著缩短了手术时间（平均从36分钟降至18分钟），并降低了围手术期并发症的发生率。
