Pregnancy complicated by liver dysfunction: possible pathogenesis of vasospasm

Area of Science:

• Obstetrics and Gynecology
• Hepatology
• Vascular Medicine

Background:

• Acute fatty liver of pregnancy, HELLP syndrome, and severe preeclampsia represent a spectrum of pregnancy-related liver disorders.
• These conditions share overlapping clinical and pathological features, complicating diagnosis and management.
• Understanding the underlying mechanisms is crucial for improving maternal and fetal outcomes.

Observation:

• A 31-year-old pregnant woman at 37 weeks gestation presented with nausea, vomiting, and fatigue.
• She developed liver dysfunction and disseminated intravascular coagulopathy, necessitating cesarean delivery for fetal distress.
• Celiac angiography revealed vascular narrowing and irregularities, suggestive of vasospasm.

Findings:

• Elevated serum endothelin levels and an increased ratio of thromboxane B2 to 6-keto-prostaglandin F1 alpha were observed.
• These hematological markers indicate endothelial dysfunction and a pro-thrombotic state.
• The patient showed rapid improvement in symptoms and laboratory values post-delivery.

Implications:

• The findings suggest that vasospasm may play a significant role in pregnancy-related liver dysfunction.
• This case supports the concept of a vasospastic syndrome complicating pregnancy.
• Further research into vasospastic mechanisms could lead to novel diagnostic and therapeutic strategies for these critical conditions.
