The cause precipitating intracranial aneurysm rupture remains unknown in many cases. It has been observed that aneurysm ruptures are clustered in time, but the trigger mechanism remains obscure. Because solar activity has been associated with cardiovascular mortality and morbidity, we decided to study its association to aneurysm rupture in the Swiss population. ⋯ We found greater radioflux, SESC sunspot number, and sunspot area to be associated with an increased count of aneurysm rupture. The clinical meaningfulness of this statistical association must be interpreted carefully and future studies are warranted to rule out a type-1 error.

Citation analysis can be used to evaluate an article's impact on its discipline. This study characterizes the most-cited articles related to skull base surgery. ⋯ An original article in a nondedicated skull base journal related to the subspecialty of skull base with a citation count of 150 or more and time-adjusted citation count of 10 can be considered a high-impact publication. An original article in a dedicated skull base periodical having a total citation count of 20 or more and an average citation count of 2 per year or more can be considered a high impact publication.

The occurrence of intraoperative rupture (IOR) of an aneurysm is one of the most precarious moments in microsurgery, and the management of IOR profoundly affects operative outcomes. ⋯ Accurate knowledge of the anatomy of the aneurysm and surrounding vasculature is the keystone to prevention and treatment of IOR. Most importantly, the surgeon must not rush prematurely to apply a permanent clip blindly in an effort to stop the hemorrhage.
