ABSTRACT
BACKGROUND AND PURPOSE:
Development of a headache after aneurysm coil embolization is not uncommon but has received little attention. The authors prospectively analyze the characteristics and risk factors of a headache after coiling in patients treated for an unruptured cerebral aneurysm. MATERIALS ANDMETHODS:
Ninety patients treated for an unruptured cerebral aneurysm over a period of 1 year, and without a headache history within a month before coiling, were enrolled in this study. All coilings were successfully performed without neurologic complications. After coiling, headache development and intensities were recorded.RESULTS:
Fifty (55.6%) patients experienced a headache (VAS score, 4.5 ± 2.02) at 7.9 (range, 0-72) hours, on average, after coiling, and all headaches resolved within an average of 73.0 (range, 3-312) hours. Univariate analysis showed that the following were significantly associated with the development of a headache age ≤ 50 years (OR 4.636, 95% CI, 1.414-15.198), hypertension (OR 0.232, 95% CI, 0.095-0.571), a packing attenuation of >25% (OR 3.619, 95% CI, 1.428-9.174), and a previous headache history (OR 2.769, 95% CI, 1.120-6.849). However, binary logistic regression showed that only a packing attenuation of >25% (P = .013, adjusted OR 3.774, 95% CI, 1.320-10.790) and no history of hypertension (P = .019, adjusted OR 3.515, 95% CI, 1.233-10.021) were independently associated with the development of a headache.CONCLUSIONS:
A headache frequently developed after the coiling of unruptured aneurysms. However, headaches were relatively benign and resolved within several days. The present study shows that no hypertension history and a packing attenuation of >25% are risk factors of headache development.
