BACKGROUND:: The most common presenting symptom for unruptured intracranial aneurysms (UIAs) is headache (HA). However, most experts believe that UIAs associated with HAs are unrelated and incidental. OBJECTIVE:: To analyze the incidence and characterization of HAs in patients with UIAs before and after treatment with either surgical clipping or endovascular embolization. METHOD:: We prospectively determined the presence, sidedness, and severity of HAs preoperatively in patients who presented to the senior author with a UIA. A validated, quantitative 11-point HA pain scale was used in all patients. The same HA assessments were performed again on these patients an average of 32.4 months postoperatively. RESULTS:: 92.45 % (n=53) of patents in this study, for whom we were able to obtain both a preoperative and postoperative pain score, had an improvement in their HAs. The average quantitative HA score was 5.87 preoperatively versus 1.39 postoperatively (P < 0.0001). There was no relationship found between the following: 1) HA severity versus aneurysm size, 2) sidedness of aneurysm versus sidedness of HA, and 3) HA improvement after surgical versus endovascular treatment. CONCLUSION:: This study suggests surgical and endovascular treatment of a UIA is associated with dramatic improvement in self-reported HA score an average of 32.4 months postoperatively.
