Being told that a vessel “cannot be opened”, or that amputation is the only remaining option, is not a fact about your leg — it is a judgement based on specific findings, usually a particular set of images read at a particular moment. Judgements of that kind can be re-examined. This page explains what such a verdict usually rests on, what a second opinion actually looks at again, and what it cannot promise. Assessment by Prof. Dr. Yusuf Kalko in Istanbul, Turkey.

In short: a second opinion is not a search for a different answer. It is a check on whether the imaging was complete, whether the foot vessels were actually assessed, whether a combined (hybrid) approach was considered, and whether infection and inflow were addressed before the conclusion was drawn. Sometimes the first verdict is confirmed. Sometimes it changes.

If any of these are present, this is not a travel decision — go to the nearest emergency department where you are now: a leg that has become suddenly cold, pale and painful; redness spreading up from a foot wound; discharge or odour; fever or shaking chills; blackening that is advancing by the day. In these situations the response is measured in hours, and arranging a trip abroad spends the window that decides the outcome.

What “it cannot be opened” usually rests on

The verdict is rarely arbitrary. It generally comes from one of the following, and each is re-examinable in a different way:

Stated reason	What a second opinion re-examines
The occlusion is long and completely blocked	Whether it was actually attempted, and by which route. Long occlusions are sometimes crossed from below (from the foot or lower leg) when an approach from above fails
The vessels are heavily calcified	Whether a technique for calcified vessels was available where the assessment was made — plaque removal from inside the vessel, for example
There is no target vessel to connect to	Whether the foot and ankle arteries were imaged in dedicated views at all. This is the most common gap: the scan stops at the knee
A previous stent or bypass has failed	Whether the failure was at the junction, along the graft, or from untreated disease above or below it
The disease is at more than one level	Whether a combined open + catheter approach in one session was considered — see hybrid vascular surgery
The patient is too high-risk for surgery	Whether a catheter-based option under local anaesthesia was weighed against open surgery
The images are old	Whether the anatomy has changed since — in either direction

A second opinion that reaches a conclusion before seeing the images is not a second opinion.

What is actually reviewed

Completeness of the imaging — above all, whether the arteries of the foot and ankle were visualised. A plan cannot be made for a target that was never pictured.
The original image files, not the report text alone. The report is a reading; the images can be read again.
Inflow and outflow together — blood has to get in and get out. Opening one level while the other stays blocked often fails, and that failure is sometimes read afterwards as “it could not be opened”.
Infection status — in an infected foot the sequence matters. Controlling infection and restoring blood supply are parallel tracks, not alternatives.
Whether the tissue is still viable — what can be salvaged, and what has already been lost.
The whole patient — cardiac and kidney status, diabetes control, mobility and what the leg is needed for. A technically possible procedure is not automatically the right one.

Limb salvage is four things at once

Where salvage is possible, it is not one operation. Four tracks run in parallel, and neglecting any one of them undermines the rest:

Restoring blood supply — by catheter, by bypass, or both in one session. Without adequate blood flow no wound heals, however good the dressing. See peripheral artery disease.
Controlling infection — antibiotics guided by culture, with surgical removal of dead tissue, sometimes more than once.
Wound care and blood sugar control — see diabetic foot.
Offloading — a wound on the sole does not heal while it is being walked on, no matter what else is done.

A minor amputation is not a failure

Many patients hear the word amputation and refuse everything that follows. The distinction matters. Removing a toe or a ray of the forefoot takes away dead tissue that has become a focus of infection, and is often done precisely to save the rest of the foot and keep the patient walking. What is being avoided is a major amputation below or above the knee. The paradox is that refusing a small procedure at the right time is one of the most reliable ways to end up needing a large one later.

What a second opinion cannot promise

This has to be said plainly. Not every limb can be saved, and an honest review sometimes confirms the first conclusion — which is itself useful, because it lets a decision be made with less doubt. What a second opinion offers is a complete assessment, not a promise of a different verdict. Any opinion that promises to reverse a conclusion before examining the images and the patient is selling hope rather than assessing a leg.

What to send

The imaging files themselves — CT or MR angiography, catheter angiography, Doppler — not only the reports. Ask for the images on a disc or as a file transfer.
Whether the foot arteries were imaged, if you know; if the scan stopped at the knee, say so.
Photographs of the wound in good light, from two angles, with something to show scale.
Operative notes from any previous bypass or stent, and what was used.
Current medicines, diabetes control, kidney function and cardiac history.
What you were told and on what basis — quote it if you can.

Timing

Timing is part of the clinical picture, not an administrative detail. In chronic, stable disease there is room to plan. Where there is spreading infection, rest pain that has appeared recently, or advancing tissue loss, the frame is weeks rather than months, and the leg may be lost to delay rather than to the disease.

How to Start From Abroad (Remote Consultation)

Send your medical reports and imaging for an initial review before travelling. Send the imaging files rather than the report alone, and say explicitly what you were told and on what basis. The practical sequence — what to send, what can and cannot be decided remotely, and what determines the length of stay — is set out on the contact page.

Frequently Asked Questions

I was told amputation is the only option. Is a second opinion worth asking for?

It is reasonable in most situations, and particularly where the foot and ankle arteries were never imaged in dedicated views, where disease sits at more than one level, or where a previous stent or bypass has failed. It is not reasonable to delay while there is spreading infection or a suddenly cold, painful leg — those need assessment where you are, now.

Can a completely blocked artery really be reopened?

Sometimes, and sometimes not. Long-standing total occlusions are harder than narrowings, and the result depends on the length, the degree of calcification and whether there is a usable vessel beyond it. What matters for a review is whether a crossing was genuinely attempted and by which route, since an approach from below occasionally succeeds where one from above did not.

What does “no target vessel” mean?

It means the surgeon found no artery beyond the blockage worth connecting to. Whether that is true depends entirely on whether the foot and ankle arteries were pictured. A scan that stops at the knee cannot answer the question, and this is the single most common gap found on review.

My father is elderly with heart disease. Would he even tolerate a procedure?

That is a fair question and part of the assessment rather than a reason to stop it. Many revascularisation procedures are now performed by catheter under local anaesthesia, which places far less demand on the heart than open surgery. General condition influences which method is chosen; it does not by itself settle whether treatment is possible.

Will a toe have to be removed if blood flow is restored?

Sometimes yes, and that is not a failure. Dead tissue does not recover once blood flow returns; restoring circulation stops the process spreading and allows the wound to heal after the dead part is removed. Success is measured by how much of the foot and walking is preserved, not by avoiding every procedure.

Can this be assessed from abroad before I travel?

The imaging can be reviewed remotely and that often settles whether a trip is worth making. A definitive plan still needs an examination, because pulse, skin temperature, sensation and the state of the wound carry information no image contains.

How quickly do I need to decide?

It depends on the picture. Stable chronic disease allows planning. Spreading infection, newly developed rest pain or advancing blackening do not — those need assessment within days, locally if necessary, before any travel is arranged.
