1. The Report That Changes Everything
There’s a specific moment in a fertility journey that hits harder than most people expect. It’s not the first month of trying. It’s not even the sixth. It’s the moment you’re lying on a table during your HSG, contrast dye is being pushed through your uterus, and the radiologist goes quiet for a second too long.
Then the report comes back. “Bilateral tubal block.” Or “Right cornual block.” Or some variation of the same gut-punch: your fallopian tubes are blocked.
For most women, this is where the mental spiral begins. Blocked tubes means the egg and sperm can’t meet naturally. The next sentence from the consulting doctor is often some version of: “You’ll need to consider assisted reproduction.”
And that’s not wrong. It’s just not always the complete picture.
Because depending on where the block is and what kind of block it is, there may be a procedure that can reopen the tube – without surgery, without hormones, without an operating theatre, and often in under 30 minutes. It’s called Fallopian Tube Recanalization. And most women have never heard of it.
2. “Blocked” Doesn’t Always Mean What You Think It Means
This is something that deserves far more airtime than it gets.
When your HSG report says “blocked,” it means that during the test, dye stopped at a certain point and didn’t spill through. That’s what the X-ray showed in that moment. (If you want to understand the HSG test itself – what happens during it, why the experience varies so wildly from one clinic to the next, and how to prepare so it hurts less – we’ve written a detailed guide on the truth about HSG pain that’s worth reading.)
But here’s what the report can’t tell you: why the dye stopped.
And the “why” makes all the difference in the world.
When a block appears proximal – meaning near the cornual end, where the tube connects to the uterus – it can be caused by very different things:
- Scenario A: The tube is genuinely scarred shut. Past infection, TB, or chronic inflammation has created dense scar tissue that has permanently closed the passage. This is a structural block.
- Scenario B: A plug of thick mucus or cellular debris is sitting at the entrance of the tube. The passage behind it is perfectly fine. The tube isn’t damaged – it’s clogged.
- Scenario C: The tubal opening went into spasm during the test. The muscle contracted, the passage temporarily closed, and the dye had nowhere to go. The tube is actually open – it just didn’t perform on test day.
All three scenarios produce the same HSG report: “blocked.”
But Scenario A needs a completely different conversation than Scenario B or C. In Scenarios B and C, the tube isn’t destroyed. It’s obstructed. And an obstruction can often be cleared.
That’s the gap FTR fills. It’s a way to find out what’s actually happening at the blockage point and, if the block is the clearable kind, to open it right there and then.
3. What Is Fallopian Tube Recanalization (FTR)?
Fallopian Tube Recanalization is a procedure done by an Interventional Radiologist to reopen blocked fallopian tubes from the inside. No incisions. No operating theatre. No general anaesthesia.
The logic is straightforward. If the block is near the beginning of the tube and if it’s the kind of block that can be cleared – a mucus plug, debris, mild scarring at the very entrance – then a very fine catheter and a micro-wire, guided by live X-ray imaging, can navigate to the exact point where the dye stopped and gently push through.
Once the wire has passed through the obstructed segment, dye is injected again. If it flows down the length of the tube and spills freely out the other end, the tube is patent. Reopened. Confirmed on screen.
That’s the whole concept. Find the block. Navigate to it. Clear it. Prove it’s open.
It sounds deceptively simple, but it requires a very specific pair of hands. Interventional radiologists spend their careers navigating tiny, delicate pathways inside the body using micro-catheters and guidewires – through blood vessels, bile ducts, urinary tracts. The fallopian tube is just another such pathway: narrow, fragile, and requiring precision rather than force.

4. Inside the Procedure Room: What Actually Happens
Knowing the theory is one thing. Knowing what it’s actually like to be on the table is another. So here’s the procedure, step by step, the way it happens when Dr. Parul Garg performs it.
Timing
FTR is preferably done around day 8–10 of the menstrual cycle. This isn’t random. It’s timed so that if the tube is successfully reopened, the very next ovulation – which happens just days later – has a clear pathway. The goal is to give you the earliest possible chance of conceiving naturally after the procedure.
The setup
You’re positioned the way you would be for a routine gynaecological exam. There’s no IV drip for general anaesthesia. No gown-and-theatre atmosphere. The room is a fluoroscopy suite – equipped with live X-ray – and you’re awake throughout. Mild sedation can be given if needed, but most women tolerate the procedure without it.
Accessing the uterus
Dr. Garg places a specialised uterine cannula gently through the cervix. This part feels similar to a gynaecological exam or an HSG. Some women feel mild cramping – period-pain level, not sharp or sudden.
Seeing the block
Contrast dye is injected and the tube openings are visualised on the live X-ray screen. The exact point where dye stops is the blockage. This isn’t guesswork – the block is being watched in real time.
Clearing the block
A very fine catheter is advanced through the uterine cavity to the opening of the blocked tube. Through this, a micro-wire – thinner than a strand of hair – is carefully navigated into the proximal segment. First, a brisk flush of contrast is used to push through any mucus or debris at the entrance. Then the wire gently advances through the obstructed area. In many cases, the block gives way because it was never a wall of scar tissue – it was a plug.
The confirmation moment
Once the wire has passed through, dye is injected again. If it flows through the full length of the tube and spills freely from the fimbrial end, the tube is confirmed open. That image on the screen – dye spilling through a tube that was “blocked” fifteen minutes earlier – is often the most emotional moment in the room. We’ve seen women tear up watching it happen in real time.
After
Everything is removed. There are no stitches because there were no cuts. Most women experience period-like cramping for a few hours and light spotting for a day or two. After a short observation period, you go home the same day.
Total time: usually about 30 minutes. Sometimes longer if both tubes need attention or anatomy is complex. But in most cases, you’re walking out of the clinic within a couple of hours of walking in.
And the part that really matters: depending on your doctor’s advice, you may be able to try conceiving naturally from the very next cycle.
5. Who Does This Work For – and Who Should It Not
This section matters more than anything else in this article. Because FTR is not magic, and it doesn’t work for every type of block. Any clinic that tells you otherwise is not being straight with you.
The profile of a woman who benefits most from FTR:
- The block is proximal. It’s at or near the cornual end – where the tube meets the uterus. This is the zone where mucus plugs, debris, and spasm-related blocks tend to sit. These are the blocks FTR was designed to clear.
- The tube beyond the block appears healthy. If the rest of the tube is normal in shape and calibre on imaging, reopening the entrance has a real chance of restoring a functional pathway.
- There isn’t widespread pelvic damage. If tubes are damaged along their entire length from severe endometriosis, pelvic tuberculosis, or major past infections, clearing the entrance alone won’t be enough. The tube needs to be healthy enough to actually function after it’s opened.
- Other fertility factors are encouraging. Ovulation is happening. Semen parameters are acceptable. The uterine cavity is normal. FTR can reopen the highway, but it can’t fix unrelated roadblocks along the route.
Where FTR is usually not the answer:
- Severe hydrosalpinx – a tube that’s dilated, fluid-filled, and visibly damaged on imaging. Opening such a tube doesn’t restore healthy function. The fluid itself can actually become a separate problem affecting fertility outcomes.
- Distal blocks – blockages at the far end of the tube, near the fimbriae (the finger-like projections that catch the egg from the ovary). These are usually caused by adhesions or structural damage, not a simple plug. A catheter from the uterine end can’t meaningfully reach or fix that.
- Active genital TB or severe ongoing pelvic infection – these need targeted medical treatment first. Attempting recanalization in an actively infected or inflamed tube would be irresponsible.
The numbers, honestly:
Recanalization is successful in close to 90% of well-selected patients with proximal blocks – meaning the tube is confirmed open on the table. Among women whose tubes are successfully reopened, about 40% conceive within the first 6 months.
That’s not 100%. And it’s not meant to sound like 100%. Fertility is complex. Many factors have to line up. But for the right candidate, FTR restores the natural pathway and gives conception a genuine chance – without hormonal stimulation, without daily injections, without any of the physical demands that come with more intensive fertility processes.
One more thing to know: a reopened tube can sometimes re-occlude over time. If it does, the procedure can be repeated.
6. Why Nobody Told You About This Earlier
If this procedure has been around for years, and the success rates are this reasonable – why is this the first time you’re hearing about it?
The answer is less dramatic than it seems.
FTR sits in the domain of Interventional Radiology. It’s not a surgery, so surgeons don’t perform it. It’s not a fertility treatment in the conventional sense, so fertility specialists don’t always have it on their radar. It lives in the gap between two specialties.
The gynaecologist or fertility consultant who reads your HSG report and sees “blocked” is trained to think along the pathways they know best. That’s not a limitation – that’s just how specialisation works. Every doctor, in every field, reaches first for the tools they use most.
Interventional radiologists think about blocked pathways differently. It’s what they do all day – unblocking blood vessels, bile ducts, urinary tracts, drainage channels. When an IR specialist looks at a proximal tubal block on an HSG film, the instinct is: “Can I get a wire through that?”
That’s not a better or worse way of thinking. It’s a different lens. And sometimes that different lens is exactly what opens a door – literally.
So if nobody has mentioned FTR to you until now, don’t assume you’ve been given bad advice. It usually means you haven’t yet spoken to the type of specialist whose daily work involves navigating and reopening blocked passages inside the body.
7. Send Your HSG. Get a Straight Answer.
If you’re reading this with an HSG report that says “blocked,” here’s what we’d suggest.
Don’t panic. And don’t assume the most intensive route is the only route.
Find out what kind of block you have. Where is it? Is it proximal? Does the rest of the tube look healthy? Is this the kind of obstruction that might respond to a 30-minute catheter procedure?
You can get that answer quickly. WhatsApp your HSG report to the clinic. No long consultations needed. No commitments. Just a clear, honest assessment of whether FTR is worth exploring in your case.
If it is – you’ve gained an option you didn’t know you had, and possibly a much simpler path forward. If it isn’t – you’ve lost nothing, and you move ahead with clarity instead of doubt.
