The Relationship

Abstract Background Migraine is a common clinical primary headache with unclear aetiology. In recent years, studies have shown that migraine is related to patent foramen ovale, and some patients with migraine have white matter lesions. However, the relationship among the three is unclear.Objective To explore the characteristics of white matter lesions (WMLs) in migraine patients with patent foramen ovale and to predict the occurrence of patent foramen ovale through magnetic resonance imaging (MRI) characteristics in patients with migraine.Methods Seventy-seven patients clinically diagnosed with migraine were examined by transcranial Doppler ultrasound (cTCD) and MRI. The patients were grouped according to the presence of WMLs, with matching by age, sex, hypertension, diabetes, PFO and other characteristic data. We observed the MRI fluid attenuation inversion recovery sequence (FLAIR) image and compared and analysed the difference in WMLs between the PFO-positive group and the PFO-negative group.Results There were 42 cases and 35 cases of migraine with and without WMLs, respectively. A statistically significant difference in near-cortical WMLs with PFO in migraine patients was observed (P=0.001). Logistic regression analysis adjusted by age, sex, hypertension and diabetes identified PFO status as the sole determinant for the presence of near-cortical WMLs (OR = 0.14; 95%CI 0.045–0.421; p < 0.001)Conclusion Near-cortical white matter lesions in migraine patients are related to PFO. Transcranial Doppler ultrasonography may reveal more PFO in patients with migraine and near-cortical WMLs.

Tomographic Angiography

This is a case report of a 35-year-old female pedestrian struck by a semi-truck. computed tomographic angiography (CTA) revealed a pseudoaneurysm at the proximal brachiocephalic artery measuring 1.8 cm in cranio-caudal length and 1.2 × 0.6 cm transverse. Just distal to the pseudoaneurysm, there was severe luminal narrowing caused by either a dissection flap or mural thrombus. Due to profound left-sided weakness, transcranial Doppler ultrasound was performed which demonstrated “hesitant” waveforms in the right middle cerebral and right vertebral arteries secondary to proximal obstruction. Hesitant waveforms display mid-systolic velocity deceleration and may also be referred to as the “bunny” waveform. Emboli monitoring of the right middle cerebral and basilar arteries were positive for active embolization
