Abstract

: Puerperal sepsis (PPS) is a severe postpartum infection that remains a significant maternal health concern. Recent evidence suggests a potential link between PPS and ovarian vein thrombosis (OVT), a rare but life-threatening complication occurring in 0.01 to 0.18% of pregnancies. Despite the historical significance of PPS and its well-documented consequences, its association with thrombosis remains underrecognized in obstetric practice. This narrative review explores the historical context, clinical presentation, diagnosis, and management of PPS and OVT while emphasizing the need for increased awareness and preventive strategies. Sepsis triggers a hypercoagulable state through inflammatory cytokine release, endothelial injury, and coagulation activation, contributing to thrombotic complications such as OVT. The right ovarian vein is more commonly affected due to anatomical factors, including uterine dextrorotation during pregnancy. OVT typically presents with abdominal pain and fever, requiring imaging modalities such as Doppler ultrasound and magnetic resonance imaging for diagnosis. Although anticoagulation therapy is widely used for deep vein thrombosis, its application in OVT remains inconsistent, despite comparable recurrence rates between the two conditions. The review also highlights the lack of consensus on thromboprophylaxis in septic postpartum patients. Although guidelines from major obstetric organizations are inconsistent, emerging evidence suggests that low-molecular-weight heparins may reduce thrombotic risk in PPS. In the absence of large-scale randomized trials, observational studies remain essential for guiding clinical decisions.
