Cardiovascular
Limb Ischemia
Severely reduced blood flow to the legs, where tissue itself is at risk.
What is Limb Ischemia?
Limb ischemia is a more advanced and serious end of the circulation spectrum — pain at rest, wounds that won't heal, or skin changes signalling that a leg or foot genuinely isn't getting enough blood to stay healthy. It's a different situation from general poor circulation or cramping on exertion; here, tissue viability itself can be threatened, and the urgency is real rather than gradual.
How regenerative medicine supports it
This always starts with vascular surgery involvement — ABI, imaging, and a surgeon's assessment of whether revascularisation is needed, since that decision takes priority over anything else. Where appropriate as an adjunct, we look at therapies supporting tissue healing and microcirculation, including hyperbaric oxygen for compromised wounds. We are honest that critical limb ischemia with tissue loss is a surgical and vascular emergency in many cases, and we decline to treat anyone who needs urgent revascularisation instead.
Treatments we would consider
Options discussed for this condition
Listed for orientation only. What is actually prescribed depends on your records.
- MSC TherapyMedical team-guided stem cell therapy using mesenchymal cells for joint, immune and whole-body recovery.
- HBOT (Hyperbaric Oxygen Therapy)Pressurised oxygen sessions supporting wound healing, recovery and tissue oxygenation.
- PRP TherapyPlatelet-rich plasma for orthopaedic, aesthetic and recovery applications.
- Ozone TherapyMedical ozone protocols for circulation, immune tone and inflammation support.
If the evidence for treating limb ischemia this way is thin, we will tell you before you book — and the review is not billed.
Limb Ischemia — Questions Patients Ask
I have a wound on my foot that won't heal — is this the right place to start?
Not as a first step — a non-healing foot wound with poor circulation needs urgent vascular assessment first, since delaying that can risk the limb. We'd only consider supportive therapy once a vascular surgeon has assessed and stabilised the situation.
How is this different from the peripheral artery disease page?
Limb ischemia refers to the more severe end of that same disease spectrum, where blood flow is so reduced that tissue health itself is threatened, rather than just pain on walking.
Can hyperbaric oxygen heal my wound instead of surgery?
No — if revascularisation is needed to restore blood flow, HBOT can't substitute for that. It's sometimes used to support healing after blood flow has been addressed, not instead of addressing it.
Would you ever turn someone away for this condition?
Yes, regularly — anyone with critical limb ischemia needing urgent vascular intervention is referred immediately rather than treated here, because timing genuinely affects whether a limb can be saved.
What can realistically be offered once I've had the vascular procedure?
Once blood flow is restored or optimised surgically, we can look at supporting tissue and wound healing alongside your surgical team's follow-up, tracked through wound measurements and ABI.
