We analyzed four personal cases and 51 reported cases of dissecting aneurysms of the arteries of the head and neck. Subintimal dissection more commonly affects the intracranial vessels before age 40. In contrast, medial dissection tends to affect extracranial vessels after age 30. Vertebrobasilar dissection more variably affects either arterial plane. The reasons for these differing patterns of dissection are still not clear. In young subjects, the subintimal layer appears to be more susceptible; in contrast, the media becomes increasingly vulnerable with age, particularly in the presence of acquired medial disease.
