This randomized controlled trial compared foam sclerotherapy and the sandwich technique for treating ovarian vein reflux in 40 women with pelvic congestion syndrome. The study found that the sandwich technique was significantly more effective in achieving symptomatic improvement and reducing vein diameter in patients with larger veins (>8 mm) compared to foam sclerotherapy, with a P-value of .007.
Key findings
- Symptomatic improvement was significantly greater in the sandwich technique group (P = .007).
- Reduction in vein diameter was more effective in the sandwich technique for veins >8 mm (P < .001).
- Both techniques had four complications each, with no significant difference between them.
Why it matters
Understanding the comparative effectiveness of these techniques can guide clinicians in selecting appropriate treatment for patients with pelvic congestion syndrome, particularly based on vein diameter.
