NCT02766972

Brief Summary

Treatment of complex unruptured intracranial aneurysms (UIA) remains challenging to date. Therefore, advanced techniques are required to achieve an optimal result in treating these patients safely. In this study, the safety and efficacy of rapid ventricular pacing (RVP) to facilitate microsurgical clip-reconstruction has been studied prospectively in a joined neurosurgical, anesthesiological and cardiological study.
