Brief Summary
Gonadal veins embolization (GVE) with nitinol or platinum coils is widely used in the treatment of PeVD caused by the valvular incompetence of gonadal, parametrial, and uterine veins. Most authors report a high efficacy of this technique in reducing blood flow through the gonadal veins (GV) and relieving symptoms of the disease. In the Society for Vascular Surgery (SVS) and American Venous Forum (AVF) guidelines, GVE is considered the standard of treatment for PeVD with a grade of recommendation 2B, due to the moderate quality of evidence. Moreover, other studies report about wide variability in the GVE outcomes, in terms of pelvic venous pain (PVP) elimination, persistence or intensification of pain after GVE, and coil migrations and protrusions. It is known that 6% to 32% of patients do not achieve significant pain relief after the procedure. The most studies of GVE in the treatment of PeVD are characterized by only a statement of the fact of any complication without investigating the causes of its development. At the same time, it is well known that it is a thorough study of complications that makes it possible to avoid failures in the future, to improve the therapeutic technique, or to abandon its use altogether. In this study, it is planned to conduct a retrospective analysis of patients' database, who have undergone gonadal veins embolization with nitinol coils.

Outcome Measures
Primary Outcomes (4)
Change in the diameter of the pelvic veins
The diameter of the pelvic veins was measured using duplex ultrasound
At baseline and 1-12 months after pelvic vein intervention
Change in the duration of pelvic venous reflux
Pelvic venous reflux was measured using duplex ultrasound. Reflux duration of more than 1 s was considered pathological
At baseline and 1-12 months after pelvic vein intervention
Postprocedural pain
The visual analogue scale is a line 10 cm long. Each centimeter corresponds to 1 point: 0 points - no pain, 10 points - maximum pain. Higher scores on the scale correspond to poorer results.
1 day, 5 days, 1 and 12 months after the intervention on the pelvic veins
Pelvic vein thrombosis
Thrombosis of non-targeted pelvic veins (parametric, uterine, internal iliac veins). Pelvic vein thrombosis was detected using duplex ultrasound
1 and 5 days after the intervention on the pelvic veins
Secondary Outcomes (3)
Hemorrhagic complications
1 and 5 days after the intervention on the pelvic veins
Other complications after embolisation
1 day, 5 days, 1 and 12 months after coil embolization
Allergic reactions
1 day, 5 days, 1 and 12 months after coil embolization
Other Outcomes (1)
Complications of anesthesia
1 and 5 days after the intervention on the pelvic veins
Study Arms (1)
Gonadal veins embolisation
This group includes patients who have undergone coil embolization of gonadal vein
Interventions
GVE was performed under local anesthesia with 5.0-10.0 mL of 0.5% lidocaine solution with a patient under intravenous sedation. For the left GV embolization, the transfemoral approach was used, while for the right or both GV embolization, the transjugular approach was used. The 5F multipurpose angiographic catheters (Cordis; USA), standard 'moving core' J .035" guidewire, and an angled hydrophilic guidewire (Radiofocus; Terumo Corp., Japan) were used. For the GV occlusion, the pushable 0.035" standard stainless steel coils (Gianturco; William Cook, Bjæverskov, Denmark) and 0.035" coils made of Inconel with interwoven long collagen fibrils (MReye; Cook Medical Inc., Bloomington, USA) were used. The diameter of coils was 8-12 mm, and the length was 10-20 cm.
Eligibility Criteria
Cohort includes 150 women who have undergone gonadal vein embolisation or endoscopic resection
You may qualify if:
- the presence of symptoms and signs of PeVD (pelvic venous pain, dyspareunia, discomfort/heaviness in the hypogastric region, vulvar varicosities);
- reflux in the gonadal, parametrial, uterine veins according to duplex ultrasound and ovarian venography;
- gonadal veins embolization with coils.
You may not qualify if:
- the presence of nutcracker and May-Thurner syndromes, confirmed by multiplanar renal and pelvic venography;
- open, endoscopic, or hybrid interventions on the gonadal and iliac veins or pelvic organs.
