REGIONAL REFERRAL CENTER
A Regional Referral Center for Advanced PAD, CLTI & Limb Salvage
Oklahoma Cardiovascular Center is built for the cases other centers turn away — complex below-the-knee and pedal disease, chronic limb-threatening ischemia, and dialysis access — alongside full-service cardiovascular care.
The technical data behind the work
We report our procedural results by the endpoint that defines them, counted on the vessels we actually attempted, to Peripheral Academic Research Consortium (PARC) / SVS reporting standards. These are procedural endpoints — not limb salvage and not wound healing, which we do not yet measure and therefore do not claim.
90.3%
per-vessel technical success, overall
6,071 of 6,720 evaluable vessels (PARC/SVS) · 1,683 consecutive procedures
91.8%
below-the-ankle (inframalleolar) technical success
3,255 of 3,544 below-the-ankle vessels — the disease other programs decline

1,645 of 1,683 cases with a recorded volume · missing volumes never assumed
Our referrals come from a wide range of clinicians, including primary care physicians, orthopedics, podiatry and wound care teams, and nurse practitioners and physician assistants, rather than a handful of sources, and many patients also reach out to us directly.
Why Patients and Physicians Choose OCC
-
Limb-salvage focus. Reopening the below-the-knee and pedal arteries that many programs do not attempt. Below-the-knee and pedal revascularization is the center of this practice, not a sideline. Below-the-Knee & Pedal Revascularization →
-
One coordinated practice: Diagnosis, in-house imaging, intervention, wound care, and follow-up under one roof, with the physician who reads your images being the physician who treats you.
-
Outpatient by design. Most procedures are same-day, through a small puncture rather than an incision.
-
Full-service cardiovascular care. Coronary, carotid, renal, venous, and heart-rhythm care beyond limb salvage. Treatments We Perform →
-
Second opinions. When amputation has been recommended elsewhere, we look again. Refer a patient →
What a limb-salvage center actually has to be able to do
The phrase gets used loosely. Below is what the work requires, and why each piece is here rather than referred out. Every clinical rationale on this page is tied to published evidence, not to our own numbers.
-
See the arteries the screening tests miss. The ankle-brachial index fails in exactly the patients who most need it to work: in one series, 60% of patients with limb-threatening ischemia had an ABI that was normal (40%) or noncompressible (20%). A complete arterial duplex from the pelvis to the toes reads flow rather than the vessel wall, so calcium does not blind it. Arterial ultrasound →
-
Measure perfusion at the wound. Pedal acceleration time can be taken beside an open ulcer or after a toe amputation, where toe pressures and skin-oxygen measurements cannot be obtained. Improvement in PAT after revascularization has been associated with limb salvage.
-
Reach the foot, not just the ankle. Published series consistently show that healing and limb salvage track with whether the below-the-ankle circulation is actually restored, not merely attempted. Why the foot’s arteries decide the wound →
-
Prepare the vessel rather than default to a stent. Treatment is sized and confirmed with intravascular ultrasound, so a permanent implant is held in reserve rather than used by default. How we treat PAD →
-
Protect a vulnerable kidney. Contrast-sparing technique and CO₂ angiography, planned against published post-contrast AKI thresholds by CKD stage. Kidney-protective vascular care →
-
Keep the wound and the artery in the same conversation. Wound-care-trained clinicians on staff, coordinating with podiatry, nephrology, endocrinology, and infectious disease. Wound care →
Where care happens, and why it matters
We work in two settings, and the choice is based on what each patient and procedure requires. Our office-based lab provides a convenient outpatient setting for procedures that do not require hospital resources. When a procedure or patient requires additional support, we use the hospital outpatient setting, where those resources are immediately available.
-
Office lab — below-the-knee and pedal revascularization, dialysis access, venous work, loop recorders.
-
Hospital outpatient — cardiac catheterization and PCI, diagnostic carotid angiography, pacemakers, ICDs, CRT devices, TEE-guided cardioversion.
-
Either, chosen by comorbidity — aortoiliac, femoropopliteal, renal, and subclavian intervention.
How we report results
We report our results one way: a defined registry, with the methodology in the open. A percentage without its definition is close to meaningless — technical success is not limb salvage, and limb salvage is not a healed wound — so every figure we publish carries the endpoint it measures, the number of vessels or procedures behind it, and the window it was measured in. We also state plainly what we do not yet measure.
The result is a single page you or your referring physician can read end to end. See our registry results →
When to call us — don’t wait for your next visit
A limb that is losing its blood supply is time-sensitive, and a foot wound with infection can move quickly.
Call our office today if you notice:
-
A wound with spreading redness, foul drainage, or new black tissue
-
Foot pain at rest, or pain that wakes you at night and eases when you hang the foot off the bed
Call our office at (918) 943-5303 and tell us what’s changed — we’ll get you seen sooner, because catching these early often keeps a small problem from becoming a big one.
Go to the emergency room now, or call 911, if you have:
-
A foot or leg that becomes suddenly cold, pale, numb, or painful
-
An infection that is spreading quickly, or a fever with a wound
For Referring Providers — We accept referrals for complex below-the-knee and below-the-ankle disease, chronic limb-threatening ischemia, non-healing wounds, dialysis access, and limbs where amputation has been recommended elsewhere. Patients are returned to your care with a written plan. Refer: (918) 943-5303 · fax (855) 312-3594.
Refer urgently: rest pain, tissue loss, ischemic ulcer, gangrene, chest pain, decompensated heart failure, new atrial fibrillation, or a clotted dialysis access. · Routinely: claudication, a non-healing wound, diabetes with a foot ulcer, or a normal ABI with symptoms that do not fit.
