Peripheral Arterial Disease (PAD) can be debilitating for those that suffer from it. PAD is caused by blockages in your arteries, most notably your legs and feet. These blockages stem from fatty deposits, known as plaque or atherosclerosis, narrowing the arteries from their normal diameter. If left untreated, PAD can cause tissue damage, which could result in amputations, stroke, or heart attacks. When caught early enough, PAD is very manageable with minimally invasive treatments available at vascular centers.
Quick Answer: Minimally invasive treatments for peripheral arterial disease (PAD) open narrowed or blocked leg arteries from the inside, using a thin catheter passed through a needle puncture instead of a large surgical incision. The main options are balloon angioplasty, drug-coated balloons, stents and atherectomy, which removes plaque. Most are outpatient procedures under local anesthesia and light sedation, and many patients go home the same day. They are usually recommended when walking pain limits daily life despite exercise and medication, or urgently when there is rest pain or a non-healing wound.
If you suspect you may have PAD, the best course of action is to schedule an appointment with a vascular specialist. Once it is determined that you are affected by vascular disease, your doctor will present you with a few options for treatment. When it comes to PAD, there are a couple of treatments that will prove effective. Open vascular surgery is a time consuming and invasive treatment, but it is really only required for severe cases. More than likely, PAD can be treated using minimally invasive endovascular treatments.
Endovascular treatments use small incisions that result in less pain and faster recovery. These types of treatments are also especially helpful for patients who have health conditions which limit their ability to receive open vascular surgery. There are two types of endovascular PAD treatments: Angioplasty and Stenting.
- Angioplasty involves making a small incision to insert a catheter, which has a small balloon on the end of it, into the affected artery. Once it is guided to the blockage, the balloon inflates, opening the artery to a more normal width.
- If the vascular specialist believes there is a risk the artery will close up again, they will use the second treatment: Stenting. A stent is a mesh wire cylinder that is inserted into the artery which prevents it from shutting. This cylinder will keep the blood flow from being restricted by a contracting artery.

What Minimally Invasive PAD Treatment Means
Peripheral arterial disease narrows the arteries that carry oxygen-rich blood to the legs. When the muscles work harder, during walking for example, they need more blood than the narrowed artery can deliver, and they cramp or ache. In advanced disease, even the skin of the foot cannot get enough blood to heal small injuries.
Minimally invasive, or endovascular, treatment works from inside the blood vessel. Through a small needle puncture, usually in the groin and sometimes in the wrist, arm or lower leg, an interventional radiologist passes a thin wire and catheter through the artery under live X-ray guidance. The blockage is crossed with the wire, then treated with a balloon, a stent, a plaque-removal device or a combination. There is no long incision, and the artery is repaired without being exposed.
Because the approach is so much gentler than open surgery, it has become the first choice for many patients, including older adults and those with heart, lung or kidney conditions that would make major surgery risky.
Signs Your PAD May Need More Than Medication
Not everyone with PAD needs a procedure. The decision depends on how much the disease affects your life and whether the leg tissue is at risk. Doctors generally group PAD into stages.
| Stage | What patients notice | Usual approach |
|---|---|---|
| No symptoms | Nothing, but a low ankle-brachial index or weak pulses | Risk factor control, walking, medication |
| Claudication (walking pain) | Cramping or aching in the calf, thigh or buttock with walking that eases with a few minutes of rest | Supervised exercise and medication first; a procedure if symptoms still limit daily life |
| Rest pain | Burning or aching in the foot at night, eased by hanging the leg over the bed | Prompt evaluation and usually revascularization |
| Tissue loss | Sores on the toes, heel or foot that will not heal, or dark, dying skin | Urgent revascularization to save the limb, plus wound care |
The last two stages together are called chronic limb-threatening ischemia. At that point, restoring blood flow is usually time-sensitive, because the foot cannot heal without it.
First-Line Care Before or Alongside a Procedure
PAD is a sign of hardening of the arteries throughout the body, not just in the legs. People with PAD have a higher risk of heart attack and stroke, so treatment always starts with protecting the whole circulation. In our practice, we review these basics with every patient, whether or not a procedure is planned:
- Stopping smoking, which is the single most important step for slowing PAD and keeping treated arteries open
- A structured walking program: walking until the pain is moderate, resting until it settles, and repeating for 30 to 45 minutes, three or more times a week. Over a few months, this often increases how far you can walk
- Medications usually include an antiplatelet drug such as aspirin and a statin, with other medicines in selected patients, as prescribed by your doctor
- Control of diabetes and blood pressure, which protects both large and small arteries
- Daily foot checks, especially for people with diabetes or reduced sensation
For many people with mild claudication, these measures are enough. A procedure is considered when walking pain keeps you from work, errands or activities you value, or when the leg is at risk.
Endovascular PAD Treatment Options Compared
Balloon angioplasty and stenting are the two best-known tools, but they are not the only ones. The choice depends on where the blockage is, how long and hard it is, and how heavily calcified the artery has become.
| Option | How it works | Often used for |
|---|---|---|
| Plain balloon angioplasty | A balloon is inflated to push plaque aside and widen the artery | Shorter narrowings, arteries below the knee |
| Drug-coated balloon | A balloon coated with medication that helps slow re-narrowing | Thigh arteries, re-narrowing inside previous treatment |
| Stent | A small mesh tube holds the artery open after angioplasty | Iliac arteries, blockages that recoil or tear after ballooning |
| Atherectomy | A tiny rotating, cutting or laser device removes or modifies plaque | Heavily calcified or bulky plaque, often before a balloon |
| Open bypass surgery | A vein or graft routes blood around the blockage through incisions | Very long blockages or failed endovascular treatment |
Often, more than one tool is used in the same session. For example, plaque may be prepared with atherectomy and then treated with a drug-coated balloon, with a stent added only if the artery does not stay open well.
How We Evaluate Peripheral Arterial Disease
At Premier Vein & Vascular Center, the evaluation is designed to answer three questions: Is PAD causing your symptoms? Where are the blockages? Is a procedure likely to help?
- Focused history. We ask how far you can walk before pain starts, where you feel it, whether you have pain at rest or wounds, and about smoking, diabetes, kidney disease, heart disease and current medications.
- Examination. We check pulses in the groin, knee and foot, the color and temperature of the feet, hair and nail changes, and any sores between or on the toes.
- Ankle-brachial index (ABI). Blood pressure cuffs at the arm and ankle compare pressures. A low ratio confirms PAD and indicates severity. Toe pressures are added when the ankle arteries are too stiff to compress, which is common in diabetes and kidney disease.
- Arterial duplex ultrasound. Performed in our IAC-accredited vascular lab, this scan shows where flow is narrowed or blocked. When more detail is needed for planning, CT or MR angiography may be ordered.
- A clear plan. We explain whether exercise and medication are the right next step, or whether a procedure is worthwhile, and which approach fits your arteries.
Leg pain is not always arterial. Night cramps, heaviness or swelling often point to vein problems, which we can check at the same visit. Our pages on leg cramping and venous insufficiency explain the difference.
What to Expect During an Endovascular Procedure
Before
We review your medications, kidney function and any contrast allergy. Most patients continue their aspirin, while some blood thinners and diabetes medicines may need adjusting. You will be asked not to eat for several hours beforehand.
During
You lie on the X-ray table, awake but relaxed with light sedation. The puncture site is numbed, and you may feel pressure but rarely pain. Contrast dye is injected to map the arteries, and the blockage is treated while we watch on screen. Many procedures take about one to two hours, depending on how many areas are treated.
After
The puncture is sealed with pressure or a small closure device. You rest lying flat for a few hours, and many patients go home the same day, while some stay overnight. Bruising at the puncture site is common. Most people are walking around the house that evening and return to light activity within a few days.
Recovery and Keeping the Artery Open
A treated artery can narrow again over time, especially in people who continue to smoke or have poorly controlled diabetes. Protecting the result is a shared effort:
- Take antiplatelet medicines and statins exactly as prescribed, and do not stop them without talking to your doctor
- Keep walking every day; exercise builds collateral vessels and keeps the treated artery working
- Attend follow-up visits with ABI or duplex ultrasound checks, often at regular intervals in the first year
- Report any return of walking pain, a cooler foot or a new sore early, since re-narrowing is usually easier to treat when caught early
You can learn more about our approach on the peripheral arterial disease treatment page, and about non-healing wounds on our leg ulcers page.
Call 911 or go to the emergency room if…
- Your leg or foot suddenly becomes painful, cold, pale or blue, numb or weak, which can mean an artery has suddenly blocked
- A toe or part of the foot turns black, or a foot wound shows spreading redness, pus or fever
- You have chest pain, shortness of breath, or sudden weakness of the face, arm or leg, or trouble speaking
- The puncture site swells rapidly or bleeds heavily after a procedure

Frequently Asked Questions
How long do stents last in the legs?
A stent is designed to stay in the artery permanently. The concern is not the stent wearing out but tissue or plaque gradually narrowing the inside of it. Not smoking, taking prescribed medications and attending ultrasound follow-up help catch and treat any re-narrowing early.
Is angioplasty for PAD painful?
Most patients feel only the numbing injection and some pressure. When the balloon is inflated, a brief ache in the leg is common and passes when it is deflated. Afterward, the puncture site may be sore and bruised for several days.
Can PAD be reversed without surgery?
The plaque itself does not usually disappear, but symptoms can improve a great deal without any procedure. A structured walking program, stopping smoking and medications such as statins can increase walking distance and lower heart attack and stroke risk.
What is the difference between PAD and poor circulation from veins?
PAD is a problem with arteries bringing blood to the leg, typically causing cramping with walking that eases with rest, cool feet and slow-healing toe wounds. Vein disease is a problem with blood returning from the leg, usually causing heaviness, swelling, varicose veins and ankle skin changes. Some people have both, and simple tests can tell them apart.
How long does recovery take after a PAD procedure?
Many patients go home the same day or the next morning and return to light activity within a few days. Heavy lifting and strenuous exercise are usually avoided for about a week while the puncture site heals. Walking is encouraged early and is an important part of recovery.
Who should be screened for peripheral arterial disease?
Screening with an ankle-brachial index is often recommended for people over 65, and for younger adults who smoke or have diabetes, high cholesterol, kidney disease or known heart disease. Anyone with walking pain in the calves, thighs or buttocks should be checked.
