ABSTRACT
OBJECTIVE: 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.
