This study aims to evaluate the prevalence of right-to-left shunt (RLS) in patients with migraine with aura compared to controls and those with ischemic stroke.
Case-control study involving 44 patients with migraine with aura, 73 patients with ischemia, and 50 controls.
All participants underwent bilateral transcranial Doppler with contrast medium injection.
Diagnosis of RLS was based on detection of at least 3 microbubbles within 15 seconds.
41% of migraine patients (18 out of 44) exhibited RLS compared to 16% of controls (8 out of 50), p < 0.005.
35% of patients with cerebral ischemia (26 out of 73) had RLS.
RLS prevalence in migraine patients is significantly higher than in controls and similar to those with ischemic stroke.
