To report our experience with PDA closure with Gianturco coils.
Between September 1995 and January 1996, nine patients underwent cardiac catheterization to have patent ductus arteriosus occlusion by Gianturco coils. Selection criteria were age > or = 6 months and narrowest PDA internal diameter < 4 mm. 4F to 6F Judkins right coronary catheters were used to deliver the coils. One loop was delivered in the pulmonary artery and two loops delivered in the descending aorta across the ductus. Angiography after the procedure confirmed complete closure. Follow-up after coil placement occurred the next day, one month and three months by means of color flow mapping.
Of the nine patients, seven had successful implants. In one no coil was delivered. In the first patient, there is a small residual shunt visualized by color flow doppler that persists after three months of the implant. One patient received two coils, other received three coils and the remainder received one coil each. There were no coil migration, or significant complication related to the implants.
The coil occlusion of the ductus is a safe, effective and low-cost procedure, and should be included among non surgical technics of ductal closure.
报告我们使用弹簧圈封堵动脉导管未闭（PDA）的经验。
1995年9月至1996年1月期间，9例患者接受了心导管检查，采用弹簧圈封堵动脉导管未闭。入选标准为年龄≥6个月且动脉导管最窄内径＜4mm。使用4F至6F的Judkins右冠状动脉导管输送弹簧圈。一个弹簧圈输送至肺动脉，两个弹簧圈经动脉导管输送至降主动脉。术后血管造影证实完全封堵。弹簧圈置入后次日、1个月和3个月通过彩色血流图进行随访。
9例患者中，7例植入成功。1例未输送弹簧圈。在第1例患者中，彩色多普勒显示有小的残余分流，植入后3个月仍持续存在。1例患者接受了2个弹簧圈，其他患者接受了3个弹簧圈，其余患者各接受1个弹簧圈。未发生弹簧圈移位，也未出现与植入相关的严重并发症。
弹簧圈封堵动脉导管是一种安全、有效且低成本的方法，应纳入动脉导管未闭的非手术治疗技术中。
