Acute oliguric renal failure in HELLP syndrome: case report and review of literature.

We describe a 32-year-old female with past medical history of preeclampsia, who presented at 29th week of gestation of her second pregnancy with abdominal pain, emesis, and diarrhea. Initial evaluation revealed hypertension, placental abruption, and intrauterine fetal death. After spontaneous rupture of membranes, a stillborn fetus was delivered. The clinical course was complicated by seizures and acute kidney injury requiring hemodialysis. She also exhibited microangiopathic hemolytic anemia, thrombocytopenia, and elevated liver enzymes (consistent with HELLP syndrome). A biopsy showed acute renal cortical necrosis.
