Clinical Report: Unrecognized Risks of Cerebral Venous Sinus Thrombosis
Overview
This study identifies significant risk factors and outcomes associated with cerebral venous sinus thrombosis (CVST) during pregnancy, highlighting the higher severity and mortality rates in early pregnancy compared to the postpartum period.
Background
Cerebral venous sinus thrombosis (CVST) is a rare but serious condition that can lead to significant maternal morbidity and mortality during pregnancy and the postpartum period. Understanding the risk factors and clinical outcomes associated with CVST is crucial for improving maternal health.

Key Findings
35.0% of CVST cases occurred during early pregnancy, while 65.0% occurred postpartum.
Higher rates of intracerebral hemorrhage (85.71% vs. 7.69%) were observed in early pregnancy CVST compared to postpartum cases.
Mortality rates were significantly higher in early pregnancy CVST (42.86% vs. 7.69%).
Lower apolipoprotein A1 levels were significantly associated with CVST occurrence (OR = 0.005, p = 0.003).
No CVST recurrence was observed in subsequent pregnancies among the surviving patients.
Clinical Implications
Lower apolipoprotein A1 levels may serve as a potential marker for assessing CVST risk in pregnant patients.
Conclusion
The findings indicate the need for monitoring of pregnant women at risk for CVST, particularly in early pregnancy.
