Abstract
This case report details a 30-year-old pregnant woman with inherited protein C deficiency who developed severe preeclampsia (PE), intrauterine growth restriction, and pancytopenia. Despite treatment, including anticoagulants, her condition worsened, resulting in postpartum mortality. Protein C deficiency, integral to the coagulation cascade, can exacerbate pregnancy's hypercoagulable state, contributing to adverse outcomes like PE. Mutations in the protein C gene can cause type I or type II deficiency, affecting protein C antigen and activity levels. The patient's history of recurrent pregnancy losses and conception via in vitro fertilization despite advisories highlights the complexities of managing pregnancy complications with protein C deficiency. Although some studies do not establish a direct link between protein C levels and PE, further research should explore thrombophilia's role in PE development and recurrence. Prospective studies investigating antithrombotic strategies in thrombophilic pregnancies could offer insights into reducing PE recurrence risks. This case underscores the need for multidisciplinary management and ongoing research to enhance clinical strategies and outcomes in high-risk pregnancies involving protein C deficiency.
