[Correspondence] Intracranial and extracranial arteries in migraine
The Lancet Neurology
It is a pity when valuable research such as that described by Faisal Mohammad Amin and colleagues is incorrectly interpreted and used to justify misleading conclusions. The investigators—who aimed to measure extracranial and intracranial arteries during attacks of migraine without aura—stated that migraine pain was not accompanied by extracranial dilatation. At first glance this assumption seems to be accurate, but on closer inspection it is misleading. The authors measured the proximal portion of the superficial temporal artery, in the retromandibular area, even though the retromandibular area is not the site of migraine pain.
