Vascular Care in Miami: PAD & Venous Disease Treatment
This page is educational and does not provide medical advice, diagnosis, or treatment. Individual results vary. Please consult a licensed physician for guidance about your specific situation.
Our endovascular procedures use small catheter-based access points instead of open surgery. That means most patients go home the same day, return to walking quickly, and avoid the long recovery and scarring of traditional vascular surgery. Dr. Pedro Martinez-Clark and his team have performed thousands of peripheral vascular procedures across Miami-Dade County.
New: Genicular Artery Embolization (GAE) for knee pain →Peripheral Artery Disease (PAD)
PAD is a circulatory condition in which narrowed arteries reduce blood flow to the limbs — most commonly the legs. Untreated, it can lead to claudication (pain when walking), non-healing wounds, and in severe cases, limb loss. We treat PAD with angioplasty, atherectomy, and stenting to restore healthy blood flow.
PAD warning signs to know
If any of these sound familiar, a conversation with a board-certified cardiologist is a good next step.
- Leg pain or cramping when walking that eases with rest (claudication)
- Leg numbness, weakness, or heaviness
- Coldness in the lower leg or foot, especially compared to the other side
- Sores or wounds on toes, feet, or legs that heal slowly or won't heal
- A change in the color of the legs or feet (pale, bluish)
- Shiny skin, hair loss, or slower toenail growth on the legs
- Weak or absent pulse in the legs or feet
- Erectile dysfunction (can be an early vascular warning sign)
Chronic Venous Insufficiency (CVI)
CVI occurs when leg veins fail to return blood efficiently to the heart, causing swelling, aching, varicose veins, skin discoloration, and venous ulcers. We offer modern catheter-based treatments — including thermal and non-thermal vein closure — that are performed in our office and require minimal downtime.
Treatment improves comfort, mobility, and the appearance of the legs, and dramatically lowers the risk of long-term complications such as venous ulcers and blood clots.

Non-surgical knee pain treatment in Miami
Genicular Artery Embolization (GAE) is a minimally invasive, image-guided procedure that reduces chronic knee pain from osteoarthritis by targeting the abnormal blood vessels driving inflammation in the knee joint — without surgery, general anesthesia, or knee replacement.
Symptoms we treat
- Persistent knee pain from mild-to-moderate osteoarthritis
- Pain that limits walking, stairs, or sleep
- Tenderness and swelling around the knee joint
- Inadequate relief from medication, injections, or physical therapy
- Patients not ready for — or wanting to avoid — knee replacement
Treatment overview
- Outpatient, image-guided procedure (about 1–2 hours)
- Performed under local anesthesia with light sedation
- Tiny pinhole access — no surgical incision
- Microscopic particles block abnormal arteries fueling joint inflammation
- Most patients go home the same day
Expected results
- Meaningful pain reduction in roughly 70–80% of patients
- Initial relief within 1–4 weeks; continued improvement over months
- Better mobility, sleep, and daily function
- Return to normal activities within a few days
- Durable benefit reported out to 1–2+ years in published studies

Conditions We Treat
As a leading cardiologist in Miami, Dr. Martinez-Clark and the amavita HEART AND VASCULAR HEALTH® team treat the full range of heart and vascular conditions using the latest minimally invasive techniques.
What to Expect at Your First Visit
Schedule your vascular evaluation
Call or request online; our team confirms insurance and books at Kendall or North Miami Beach — typically within a week.
Symptom review & focused exam
We map your symptoms, examine pulses, skin, and swelling, and review any prior imaging you bring.
Non-invasive testing in-office
Most patients get ankle-brachial index (ABI), Doppler ultrasound, or vein-reflux studies during the same visit when needed.
Plain-language diagnosis
You'll leave understanding what's going on with your circulation and which treatment options fit your goals.
In-office minimally invasive treatment
If a procedure is warranted, most vascular treatments are performed in our office through a pinhole — home the same day.
Concerned about leg pain, swelling, or vein issues?
A short vascular evaluation identifies whether PAD, CVI, or another circulation issue is the cause — and most treatments are done in our office.
