“…Further, the headache resolved within 1 month of its onset in almost all our patients. Several previous reports have investigated the characteristics of headache due to unruptured IC-VAD (6,9,10). Their results almost completely corresponded with our results in terms of the headache characteristics.…”

“…On the other hand, the headache characteristics of unruptured IC-VAD (i.e. ischemic and headache types) are not well known, and it is difficult to diagnose IC-VAD in patients presenting with only headache to the outpatient clinic or emergency department (6,9,10,15). The fact that it takes a long time to diagnose this condition also reflects the difficulty in its diagnosis (6,16).…”

“…Hence, the majority of cervicocephalic arterial dissections in Asia are IC-VAD. It is well known that headache is the most common initial symptom in patients with IC-VAD (6,(9)(10)(11)(12)(13). IC-VAD is divided into three types based on the clinical symptoms: hemorrhagic type, ischemic type and headache type (14).…”

Background and purpose It is sometimes difficult to diagnose intracranial vertebral artery dissection in patients with headache as the only symptom. Knowledge of the characteristics of the headache would facilitate the diagnosis. In this study, we aimed to clarify the characteristics of intracranial vertebral artery dissection-related headache using our original self-administered questionnaire. Methods Via the questionnaire, we ascertained headache characteristics and investigated whether they differed between two types of unruptured intracranial vertebral artery dissection, headache type and ischemic type, based on analysis of the responses. Then, we tried to validate the consistency of commonly used criteria for intracranial artery dissection by comparing them with our results. Results Thirty-seven patients were analyzed. Our results identified the following seven headache characteristics in patients with intracranial vertebral artery dissection: (i) occurring in the occipitonuchal region (89%); (ii) unilateral (81%); (iii) pulsatile (70%); (iv) of acute onset (70%); (v) severe (73%); (vi) without nausea or vomiting (73%); and (vii) with concomitant clinical symptoms unrelated to ischemia (81%). Comparison of headache characteristics between the two types of intracranial vertebral artery dissection headache showed that the pain was significantly more severe in headache type than ischemic type intracranial vertebral artery dissection ( p = 0.01). Concomitant clinical symptoms occurred significantly more often in ischemic type than headache type intracranial vertebral artery dissection ( p = 0.03). Our results generally satisfied the established headache diagnostic criteria. Conclusion The pain characteristics of headache type and ischemic type intracranial vertebral artery dissection shown in our study may facilitate its diagnosis.
