Therapeutic plasma exchange in acute fatty liver of pregnancy: a case report and literature review
Abstract
Acute fatty liver of pregnancy(AFLP) is characterised by acute liver failure that occurs most commonly in the third trimester of pregnancy. Emergent delivery of the foetus reverses liver failure in most cases. Rarely, termination of pregnancy may not reverse liver failure, and adjunct interventions may be required. Therapeutic plasma exchange (TPE) has been described in AFLP in very few reports. We describe a patient in whom liver failure and extrahepatic organ failure persisted four days after delivery. She underwent TPE for persistent liver failure which resulted in prompt clinical improvement. We propose that TPE be considered as a measure to salvage AFLP patients with liver failure that does not reverse after termination of pregnancy.
