Migraine has been found to be associated with patent foramen ovale. However, in practice, it is difficult to show that microemboli via patent foramen ovale can induce a migraine attack. Our patient showed transient sulcal hyperintensities on fluid-attenuated inversion recovery images during a migraine attack. This supports the hypothesis that microemboli via right-to-left shunt may induce migraine attacks through transient occlusion of microcirculation.
偏头痛与卵圆孔未闭有关。然而，在实际中，很难证明卵圆孔未闭的微栓子会引发偏头痛发作。我们的患者在偏头痛发作期间，FLAIR 图像上出现短暂的脑沟高信号。这支持了通过右向左分流的微栓子可能通过短暂性微循环闭塞引发偏头痛发作的假说。
