A case of sudden multiple hematomas during cesarean section due to amniotic fluid embolism

Abstract

IntroductionWe report a case of multiple hematomas, a rare manifestation of amniotic fluid embolism (AFE), during cesarean section. Presentation of caseThe patient had a history of pregnancy and cesarean section birth due to placental abruption. At 38 weeks and 2 days, her membrane ruptured, and an emergency cesarean section was performed. During uterine suturing, hematomas suddenly formed in multiple locations, and bleeding began. Intraoperative blood tests revealed decreased hemoglobin and fibrinogen levels, leading to the administration of red blood cells and fresh frozen plasma. Despite initial transfusions, hemoglobin and fibrinogen levels did not increase, necessitating additional transfusions, which ultimately improved the hemoglobin and fibrinogen levels. A post-discharge blood draw showed decreased C3 levels, supporting a diagnosis of disseminated intravascular coagulation (DIC)-type AFE. DiscussionThe sudden onset of hematomas in multiple locations other than the uterine incision wound was an atypical presentation of AFE in this case. The multiple hematomas were caused by DIC-induced hemostasis, and the decreased C3 level in the blood test supported the diagnosis of DIC-type AFE. ConclusionMultiple hematomas may occur as a symptom of DIC-type AFE and require attention.
