Abstract

BACKGROUND:

To investigate the association between headache outcomes and coil embolization and to identify potential factors associated with different headache outcomes in patients with unruptured intracranial aneurysms (UIAs) after treatment with coil embolization.

METHODS:

A prospective study of patients with planned coil embolization for UIAs was conducted. The changes in headache patterns, headache-related disability, and depression were assessed before coil embolization and at 3 days and 2 and 6 weeks after coil embolization. All variables were analyzed to identify factors associated with different headache outcomes.

RESULTS:

Fifty-nine (72%) of 82 patients reported headaches before coil embolization. Of these, improvements in the severity of headaches were reported by 42 patients (71%). In addition to a significant reduction in headache severity, significant reductions in headache-related disability and depression scores also were observed. Demographic factors, aneurysmal characteristics, or procedural factors were not found to be significantly associated with improvement in the severity of headaches after coil embolization. In addition, the number of microemboli on diffusion-weighted imaging was not significantly associated with improvement of headaches after coil embolization. Twenty-three patients reported no headaches before coil embolization, and 3 (13%) patients reported new-onset headaches after coil embolization. All new-onset headaches were mild and dull in nature without combined symptoms in the temporal area.

CONCLUSIONS:

Our study suggested that regardless of headache characteristics, the aneurysm size (even those <5 mm in diameter), technique used (stent-assisted or not stent-assisted), and coil embolization of UIAs resulted in headache improvement in most patients with pretreatment headaches.
