Hepatic Infarction in Pregnancy: A Systematic Review.
American journal of obstetrics & gynecology MFM. 2024 April 14
OBJECTIVE: Hepatic infarction is a rare complication of pregnancy most often associated with hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome. The objective of this review is to identify risk factors, presenting signs and symptoms, methods of diagnosis, and best management practices based on published case reviews.
DATA SOURCES: PUBMED and MEDLINE: OVID databases were searched for citations regarding hepatic infarction in pregnancy or the postpartum period since database inception until the study date of December 18, 2023. Keywords included "liver infarction" OR "hepatic infarction," AND "pregnancy" OR "obstetrics."
STUDY ELIGIBILITY: Case reviews or case series published in the English language were included. Our study was registered with PROSPERO (#CRD42023488176) and was conducted in accordance with published PROSPERO and MOOSE guidelines.
STUDY APPRAISAL: Included papers were evaluated for bias using a previously published tool by Murad et al (2018).
RESULTS: A total of 38 citations documenting 50 pregnancies published between 1979 - 2023 were included. Of these, 34% had a history of hypertensive disease, 26% had antiphospholipid syndrome (APS), and 22% had a history of thrombus. Of those without a pre-existing diagnosis of APS, 24% tested positive during hospitalization. Most patients presented with epigastric or right upper quadrant pain (78%) and 32% and 16% had severe blood pressure (BP) or mild BP, respectively. Sixty-four percent of patients presented with transaminitis. Forty-six percent of patients delivered preterm and 32% of pregnancies ended in intrauterine fetal demise, abortion, or early termination of pregnancy for maternal benefit. CT scan was used to confirm diagnosis of hepatic infarction in 58% of cases, MRI in 14%, and ultrasound in 6%. In cases that described management, treatment was always multimodal, including antihypertensives (18%), therapeutic anticoagulation (45%), blood product transfusion (36%), plasma exchange or intravenous immunoglobulin (20%), and steroids (39%). Transfer to the intensive care unit was required in 20% of cases.
CONCLUSIONS: Hepatic infarction should be considered in all cases of HELLP, but specifically in patients with a history of APS who present with epigastric or right upper quadrant pain. The diagnosis can usually be confirmed with CT scan alone, and management should be prompt with supportive care, therapeutic anticoagulation, and steroids.
