Abstract
BACKGROUND: Acute water intoxication after hysteroscopy is a rare, life-threatening condition, often accompanied with delayed diagnosis owing to masked symptoms because of general anesthesia. CASE PRESENTATION: Herein we presented a 39-year-old female who presented with cardiac arrest after hysteroscopic myomectomy because of acute water intoxication and survived after extracorporeal membrane oxygenation, continuous venous-venous hemofiltration, and aggressive high sodium fluid resuscitation. CONCLUSION: Failure to recognize and treat this condition appropriately may lead to potentially lethal cardiopulmonary complications.
