脑卒中患者经导管封堵卵圆孔临床资料分析

Transcatheter closure in patients with stroke clinical analysis of the foramen ovale

目的:探讨经导管封堵卵圆孔未闭(PFO),预防脑部矛盾栓塞并评价其疗效。方法:本组共6例,年龄16～67岁,均经临床经胸超声心动图或经食道超声心动图检查,证实为PFO合并右向左分流患者。6例术前均有缺血性脑梗死。患者选用PFO封堵器经导管置入,进行介入治疗。结果:本组封堵成功率为100%。所有患者均能成功置入并释放封堵器。术后1个月、3个月及6个月行经胸超声心动图检查,未见封堵器移位。术后未有脑卒中事件。结论:经导管封堵PFO是一种较有效的介入治疗方法,可用于预防由于DFO导的致脑部矛盾栓塞。

Objective：Transcatheter closure patent foramen ovale（PFO） to prevent brain embolism and to evaluate its efficacy contradictions.Methods：The group of 6 patients,aged 16～67 years,were confirmed by clinical and transthoracic echocardiography or transesophageal echocardiography confirmed the PFO with a right to left shunt.6 cases were before the ischemic stroke.PFO closure devices in patients with catheter use set of people,the interventional treatment.Results：The group of block success rate was 100%.All patients were successfully implanted and can release the occluder.After 1 month,3 months,6 months,transthoracic echocardiography revealed no displacement of the occluder.No postoperative stroke events.Conclusion：Transcatheter PFO closure is a more effective intervention methods can be used for the prevention of patent foramen ovale as the conflict led to cerebral embolism.
