Headache secondary to cervical artery dissections: practice pointers.

Abstract

Cervical artery dissections may present with mild and misleading symptoms such as a headache or cervical pain. In the absence of early diagnosis and therapy, such patients may have a high risk of cerebrovascular events. In order to refine evaluation of cervical artery dissections, we report the experience of a single center, focusing on clinical findings (e.g., headache and pain-related features at onset). From 2012 to 2017, 49 patients with cervical arteries dissections were admitted to our institution; 28 out of 49 patients (57%) presented with a headache or cervical pain, which were evaluated according to the International Classification of Headache Disorders (ICHD-III beta). Item C3a of ICHD-III beta ("pain is severe and continuous for days or longer") was present in all patients symptomatic for a headache. Another common characteristic was the recent onset, with an average (± SD) timing from the onset of a headache to the first neurologic evaluation of 3 (± 2) days (range 1-5). A refined clinical evaluation of patients presenting with a headache at the Emergency Department could improve the early detection and management of patients with cervical artery dissections, in particular when presenting without other associated neurological symptoms.
