Venous Air Embolism Not Amniotic Fluid Embolism

I read the case report by Kang et al.[1] published in the Journal with interest. In their report, amniotic fluid embolism developed in a 41-year-old woman who underwent laparoscopic repair of bladder injury and closure of a perforated uterine wall, complicating dilatation and curettage for the second trimester termina-tion of pregnancy. The hypoxia this patient developed was so severe that authors had to use extracorporeal membrane oxygenation (ECMO) to save the patient’s life. However, the diagnosis authors made deserves some comments.
