The article presents the technique of duplex ultrasound study (DUS) of the pelvic veins in patients with pelvic venous disorders (PeVDs). It provides basics of anatomy of pelvic veins and describes hemodynamic and anatomical parameters that should be assessed during DUS of pelvic veins.

- * Researchers used metagenomic and cultivation-based methods to analyze the microbiomes and found stable microbial communities similar to those from critical early Earth periods, indicating a link between present-day microbes and historical biospheric evolution.
- * The Upper Jurassic aquifer, rich in CO and influenced by magmatic processes, hosts a unique ecosystem that may reflect early Earth conditions, contributing valuable insights into microbial evolution and the formation of the modern biosphere.
Purpose: To develop a strategy for the iliac vein stenting in patients with a combination of the left common iliac vein (LCIV) compression stenosis and pelvic venous insufficiency (PVI).
Methods: This prospective comparative cohort study included 55 patients with hemodynamically significant LCIV stenosis out of 285 females with PVI screened in 2014-2022. All 55 patients underwent duplex ultrasound, multi-detector computed venography, ovarian venography, and multiplanar pelvic venography.
Background: To study and compare the effects of venoactive drug (VAD) therapy and ovarian vein embolization or resection (OVE or OVR, accordingly) on the levels of vasoactive peptides and cytokines in patients with pelvic venous disorders (PeVDs).
Methods: The study included 70 consecutive female patients with PeVD symptoms, such as chronic pelvic pain (CPP), dyspareunia, dysuria, and vulvar varicosities. Based on the results of clinical examination and duplex ultrasound of the pelvic veins, the patients were allocated to the VAD therapy (n = 38) or OVE/OVR (n = 32).
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.
