[Migraine and the idiopathic Raynaud phenomenon].

The successive onset of spasms of distal arteries of the limbs and complicated migraine in a young migrainous woman raised the possibility of a common mechanism for both disorders. Three similar cases have been reported and two recent epidemiological studies have shown the frequent association of migraine attacks and Raynaud's phenomenon or variant angina in a individual patient. The possible role of vasospasm in triggering the migrainous aura is discussed.
