Intraoperative Pulseless Electrical Activity Cardiac Arrest during Intracranial Aneurysm Clipping: Case Report

Abstract

Background: Cardiac arrest is a rare intraoperative complication with few cases reported during neurosurgery. Proposed causes of PEA cardiac arrest in this setting include medications, irrigation, coronary vasospasm, and elicitation of the trigeminocardiac reflex.Case description: Here, we report the case of a 52-yearold man who suffered an intra-operative pulseless electrical activity (PEA) cardiac-arrest while undergoing elective clipping of a right MCA bifurcation aneurysm through pterional craniotomy.
