HELLP syndrome (hemolysis, elevated liver enzymes, low platelet count) is a relatively rare complication of pregnancy. It usually develops in the IIId trimester or after delivery. HELLP syndrome is associated with increased maternal (placental abruption, disseminated intravascular coagulation, hepatic hematomas and rupture, and acute kidney injury) and neonatal (prematurity, low birth weight) risk complications. In this article the diagnosis, clinical picture and treatment of this disease have been shortly reviewed.
