Abstract
BACKGROUND: Controlled hypotension is an important tool in the open treatment of complex intracranial aneurysms. Of the available methodologies, rapid ventricular pacing (RVP) provides titratable, sustained hypotension with a relatively safe profile. METHOD: We report the case of a 63-year-old woman who underwent a combined subfrontal and subtemporal approach for clipping of anterior communicating artery and basilar apex aneurysms. RVP was used during initial dissection of the basilar apex aneurysm and perforators but caused uncontrolled ventricular tachycardia requiring synchronized defibrillation. After restoration of hemodynamic stability, the aneurysm was uneventfully clipped. CONCLUSION: Preparation for unstable cardiac arrhythmias is needed with RVP.
