Atrial fibrillation with hemodynamic instability after the use of the third dose of adenosine during surgery for 7 intracranial aneurysms: case report

Abstract Adenosine-induced asystole is a technique that prevents and controls the intraoperative rupture of cerebral aneurysm, facilitating temporary, and/or definitive clipping of the aneurysm. This is the case of a 58-year-old woman who underwent clipping of 7 intracranial aneurysms, who was induced asystole with adenosine 3 times and developed atrial fibrillation with hemodynamic instability after the last dose. Adenosine has been shown to be useful and safe, however, its use should be planned and possible cardiological complications should be considered. Resumen La asistolia inducida por adenosina es una técnica que previene y controla la ruptura intraoperatoria de aneurisma cerebral, facilitando el clipaje temporal y/o definitivo del mismo. Presentamos el caso de una mujer de 58 años intervenida para clipaje de 7 aneurismas intracraneales, a quien se le indujo asistolia con adenosina en 3 oportunidades y desarrolló fibrilación auricular con inestabilidad hemodinámica tras la última dosis. La adenosina ha demostrado ser útil y segura, sin embargo, debe planificarse su uso y considerar eventuales complicaciones cardiológicas.
