Review Case ReportsSpontaneous liver hematoma in pregnancy not clearly associated with preeclampsia: a case presentation and literature review.
Spontaneous liver hemorrhage with formation of subcapsular hematomas and rupture of Glissan's capsule is a rare but often lethal complication of pregnancy. This entity has usually been associated with severe preeclampsia or the HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome. ⋯ The literature on liver hematomas in pregnancy published since 1982 when the term HELLP syndrome was coined is reviewed with a focus on the association of liver hematomas with preeclampsia and the HELLP syndrome. Therapy and maternal and neonatal outcomes for this entity are reassessed.
