To assess the incidence of pelvic vein thrombosis (PVT) and outcomes of anticoagulant therapy for PVT in patients with pelvic venous disorders (PeVDs).
Methods
This prospective cohort study included 588 female patients with PeVDs underwent clinical examination followed by duplex ultrasound of the pelvic veins in 2021-2023. Patients with PVT were administered with anticoagulant therapy in an outpatient setting using low molecular weight heparins at a therapeutic dose.
Results
PVT was detected in 7.6% of patients with PeVDs and was symptomatic in 28.8% of them. The majority of asymptomatic patients had thrombosis in only one of the parametrial veins (90.6%). Anticoagulant therapy resulted in the PVT symptoms relief in all patients within 10 days and recanalization of the pelvic veins in 1-3 months.
Conclusion
In our study, PVT was diagnosed in 7.6% of patients with PeVDs. Anticoagulant therapy is effective and safe in resolving PVT symptoms.
