Are you or a loved one facing the frightening possibility of foot amputation due to a non-healing ulcer? Consider whether you may be a candidate for a leading-edge procedure called Deep Venous Arterialization (DVA) that’s offering new hope for patients with chronic limb-threatening ischemia (CLTI).
Chronic limb-threatening ischemia (CLTI) is a severe form of peripheral artery disease (PAD) where blood flow to the legs and feet is critically restricted. This condition can result in non-healing ulcers, severe pain, and, in many cases, lead to amputation. Unfortunately, many patients don’t receive the high-intensity vascular care needed to avoid these outcomes, resulting in unnecessary limb loss. Fortunately, DVA could provide a solution.
What is Deep Venous Arterialization?
DVA is a minimally invasive procedure designed to restore blood flow to the foot by redirecting blood through existing veins. Here’s how it works:
- Redirection of Blood Flow: Using advanced imaging and techniques, we reroute blood from the arteries to the veins in your foot.
- Vein Transformation: Over time, these veins adapt and mature, allowing oxygenated blood to reach the tissues that need it.
- Restored Healing Potential: This increased blood flow promotes wound healing, reduces pain, and saves the limb from amputation.
Who is DVA for?
DVA is typically considered for those who:
- Have non-healing ulcers on their feet
- Have exhausted all other revascularization options
- Are facing the possibility of major amputation
DVA is often considered a ‘last resort’ option because it involves using veins to carry arterial blood, which is not their natural function. This makes it a complex procedure that is only attempted when standard treatments have failed.
The Promise of DVA: Latest Outcomes
While DVA is still considered an advanced and relatively new procedure, early results have been promising:
- Limb salvage rates range from 60-80% at one year
- Many patients experience significant pain reduction
- Improved tissue perfusion is often observed, helping promote wound healing
What to Expect with DVA
DVA is a minimally invasive procedure, but it’s important to have realistic expectations about the process:
- Healing occurs over several months as your veins adapt to the new blood flow.
- Patients may not see immediate results, but improvements in blood flow help wounds heal gradually.
- In some cases, additional procedures are required to ensure the DVA remains open and continues functioning optimally.
- Pain and swelling are expected, especially in the initial stages of recovery.
Success with DVA requires patients to strongly commit to attending all follow-up appointments and potentially undergoing additional procedures. While the goal of DVA is limb preservation, it’s important to remember that some cases may still require amputation if the procedure doesn’t restore enough blood flow.
Frequently Asked Questions About DVA
How does DVA work?
DVA is a minimally invasive procedure that redirects blood from the arteries to the veins in the foot. This allows oxygen-rich blood to nourish tissues previously starved of blood supply.
What are my chances of keeping my foot with this procedure?
Current data shows a 60-80% limb salvage rate at one year. However, individual results may vary depending on your overall health and response to treatment.
How long is the recovery process?
Recovery typically takes several months. During this time, we closely monitor wound healing and blood flow improvement.
Will I need multiple procedures?
Follow-up procedures may be necessary to ensure that the DVA continues to function properly and support blood flow.
Are there any risks or side effects?
Pain and swelling are common side effects. The primary risk is that the procedure may not prevent amputation if blood flow can’t be restored.
What happens if DVA doesn’t work for me?
If DVA fails to restore blood flow, amputation may still be necessary. However, DVA provides a potential option for patients who have exhausted other treatments.
Will my insurance cover this procedure?
Most insurance plans cover DVA for eligible patients. Work with your provider to ensure that you understand your coverage options.
The Future of Limb Preservation
DVA represents a significant advancement in our efforts to prevent limb loss in patients with CLTI. While it’s not a guaranteed solution for everyone, it offers hope for those without other options. As we continue to refine the technique and gather more long-term data, we’re optimistic about its potential to improve patient outcomes.
If you or a loved one are facing the possibility of amputation due to CLTI, don’t lose hope. DVA might be an option to save your limb. It’s crucial to seek high-intensity vascular care from experienced professionals who are up to date with the latest limb preservation techniques.
We understand that facing the possibility of amputation can be emotionally challenging. Our team at VIE is here to support you medically and by providing the information and reassurance you need during this difficult time.
