Abstract

The co-occurrence of headaches and cerebral aneurysms is common in clinical practice, although a clear causal relationship has not been ascertained. We aimed to investigate the impact of endovascular obliteration of aneurysms on headaches using a cross-sectional, prospective, open-label protocol. We also sought to characterize the preexisting headaches in patients harboring cerebral aneurysms using the International Classification of Headache Disorders criteria. A total of 33 patients were recruited into the study and underwent endovascular treatment for obliteration of their aneurysms. A standardized survey was administered before and 3 to 6 months after the procedure, documenting the HIT-6 scores as well as the headache frequency. The study cohort included 25 women and 8 men. In 61% of cases, the aneurysms were located in the posterior circulation. We achieved grade 0 or 1 obliteration of aneurysms in 100% of cases and there were no complications. The mean for HIT-6 scores were 52.3 at baseline and 49.6 postprocedure (student t test, P<0.047). The headache frequency measured as total headache days per month did not demonstrate statistical significance. Our data indicated that more than half of our cohort had preexisting heada...Continue Reading
