Embolisation for pelvic congestion: what actually happens

This is the treatment most of our community asks about — before it with worry, after it with "is this normal?". Here's the realistic version, start to finish. Everything below is what to discuss with your specialist, not a substitute for their advice about you.

What the procedure actually is

Through a small puncture in the neck or groin, a thin catheter is steered under X-ray into the faulty vein — usually an ovarian vein refluxing backwards. The vein is then closed from within, typically with tiny metal coils, often plus a foam or liquid agent for the surrounding network. Blood immediately reroutes through the many healthy veins nearby; the pooling that caused the dragging ache stops.

It's done by an interventional radiologist, usually with local anaesthetic and sedation. Skin cut: none — a plaster covers it.

The day, and the weeks after

• Day 0: the procedure takes roughly an hour; you're observed for a few hours and usually home the same day.
• Days 1–14: cramping, a dull pelvic ache and tiredness are common and expected — the closed vein is inflaming down (sometimes called post-embolisation syndrome, occasionally with a low-grade temperature). Most women take it gently for a few days; ask your team about lifting and exercise, which are usually reintroduced gradually over a couple of weeks.
• Weeks to ~3–6 months: this is the honest timeline for judging the result. Relief tends to build as the congestion drains — women who judge at week two often judge too early.

Call your team promptly for fever, severe or escalating pain, or a swollen leg — rare, but not for waiting out.

Does it work?

Systematic reviews of the published series report substantial and durable pain relief for the majority of women — commonly quoted in the range of around three in four improving meaningfully. Two honest caveats belong next to that number: the studies are mostly single-centre series rather than large randomised trials, and results depend on treating the right problem — if a compression (May-Thurner, Nutcracker) is driving the reflux, closing veins downstream without addressing it can underdeliver. That's why the full venous work-up matters before anyone reaches for coils.

The coil worries, answered honestly

• "A foreign object stays in me?" Yes — the coils are permanent. They're made of the same alloys as heart stents, sit inside a closed vein, and the body incorporates them. Modern coils are MRI-conditional (tell any future radiographer you have them; airport security is a non-issue).
• "Can it make me worse?" Serious complications are uncommon; coil migration and reactions are rare and your specialist should walk you through the numbers for their own practice. Some women do have prolonged post-procedure pain — real, usually self-limiting, and worth a follow-up rather than silent worrying.
• "I react to implants (Mirena, breast implants)." Raise it explicitly — alternatives exist (sclerosants/glue, or treating a compression with a stent instead), and sensitivity history changes the conversation. It's a question for the consultation, not a reason to self-exclude.
• "Can I still have children?" Embolisation closes a faulty vein, not reproductive organs; pregnancies after embolisation are well described. If you're planning a baby soon, timing (before vs after) is a genuine discussion — bring it up.

Questions to bring to the consultation

• "Is my reflux the primary problem, or is a compression driving it?"
• "Coils, foam, glue — what will you use for me, and why?"
• "What results and what recovery do your patients typically see?"
• "What symptoms after the procedure should make me call you?"
• "If this doesn't relieve the pain, what's the next step?"
