Patent foramen ovale (PFO) is common and only rarely related to stroke. The high PFO prevalence in healthy individuals makes for difficult decision making when a PFO is found in the setting of a cryptogenic stroke, because the PFO may be an incidental finding. Recent clinical trials of device-based PFO closure have had negative overall summary results; these trials have been limited by low recurrence rates. The optimal antithrombotic strategy for these patients is also unknown. Recent work has identified a risk score that estimates PFO-attributable fractions based on individual patient characteristics, although whether this score can help direct therapy is unclear.
卵圆孔未闭（PFO）很常见，与中风的相关性很小。健康个体中PFO的高患病率使得在隐源性中风患者中发现PFO时难以做出决策，因为PFO可能是偶然发现的。最近基于装置的PFO封堵临床试验的总体汇总结果为阴性；这些试验受到低复发率的限制。这些患者的最佳抗栓策略也尚不清楚。最近的研究确定了一个风险评分，该评分可根据个体患者特征估计PFO归因分数，尽管该评分是否有助于指导治疗尚不清楚。
