许多研究表明有先兆的偏头痛（MA）与卵圆孔未闭之间存在关系。血液的右向左分流（RLS）可以解释MA发作的发生，以及这些患者缺血性卒中风险的增加。我们对120例MA患者进行了对比增强经颅多普勒检查，评估了RLS的患病率和特征。我们在其中61例中发现了RLS。28%的患者存在潜伏性RLS，72%的患者存在永久性RLS，52%的患者存在幕帘样改变。
Many lines of research have suggested a relationship between migraine with aura (MA) and patent foramen ovale. Right-to-left shunt (RLS) of blood might explain both the occurrence of MA attacks, as well as the increased risk of ischaemic stroke in these patients. We evaluated the prevalence and the characteristics of RLS in a series of 120 MA patients, who were studied with contrast-enhanced Transcranial Doppler examination. We found RLS in 61 of them. A latent RLS was found in 28%, a permanent RLS in 72%, a shower-curtain pattern was detected in 52% of the studied patients.
