HBOT Referrals from
Vascular Surgery
Partner in Care
Vascular surgeons are essential partners in chronic wound and limb salvage care. We work closely with vascular teams to ensure that patients have optimized perfusion before — or in parallel with — HBOT, and that HBOT is added when it has a reasonable chance of contributing to limb salvage.
Referral Guide
When to Refer & What to Include
Conditions to consider for HBOT referral
- Chronic non-healing wounds after vascular optimization, including diabetic foot ulcers meeting Ontario clinical criteria for HBOT eligibility
- Compromised tissue flaps following lower extremity reconstruction
- Selected post-amputation wound healing problems
- Post-revascularization chronic wound failure
The Evidence
Evidence Highlights
- HBOT is most effective when macrovascular perfusion has been optimized — angioplasty, bypass, or endovascular intervention should generally precede or run in parallel with HBOT for chronic ischemic wounds.
- Kranke 2015 Cochrane review supports improved short-term healing of diabetic foot ulcers with HBOT in selected patients.
Timing & urgency
We prefer to coordinate timing of HBOT with completion of macrovascular intervention. We are happy to discuss case-specific timing by phone.
A wound at meaningful risk of significant deterioration is an urgent referral — call us directly to discuss.
