The association between migraine with aura and persistent foramen ovale (PFO), as well as other right-to-left shunts, is described. A hypothesis that might explain this association is discussed. Observational studies suggested that when a PFO is closed patients who have migraine with aura are usually improved. The Migraine Intervention with STARFlex Technology (MIST) Trial was a randomised double-blind trial in patients with severe intractable migraine with aura and a moderate-large PFO that compared implantation of STARFlex devices with the intention of closing their PFO versus a sham procedure. It was hoped that the trial would demonstrate whether PFO closure would cure migraine. A series of problems in design and execution of the trial are discussed.
偏头痛先兆与卵圆孔未闭(PFO)以及其他右向左分流之间的关联已被描述。本文讨论了一种可能的解释该关联的假说。观察性研究表明,当 PFO 关闭时,偏头痛先兆患者通常会得到改善。采用 STARFlex 技术的偏头痛干预(MIST)试验是一项针对严重难治性偏头痛先兆且存在中大型 PFO 的患者进行的随机双盲试验,该试验比较了 STARFlex 装置植入以关闭 PFO(实验组)与假手术(对照组)对偏头痛的治疗效果,试验旨在证实 PFO 关闭是否能治愈偏头痛。本文讨论了该试验在设计和实施过程中出现的一系列问题。
