Peripheral angioplasty is a minimally invasive procedure that can improve blood flow through narrowed or blocked arteries outside the heart, most often those that supply the legs and feet. This treatment approach is commonly used for peripheral artery disease (PAD), a condition in which a buildup of plaque restricts the amount of oxygen-rich blood reaching the muscles and tissues. PAD may cause symptoms such as leg pain with walking and, in advanced cases, contribute to nonhealing wounds and other limb-threatening complications.
Tampa General Hospital (TGH) offers a comprehensive range of vascular surgery services to patients throughout Brooksville, Spring Hill, Crystal River and surrounding communities. Peripheral angioplasty procedures are performed at TGH Brooksville, with vascular care available to patients across the region.
What Is Peripheral Angioplasty?
Peripheral angioplasty, also known as peripheral vascular angioplasty, is a catheter-based treatment that can help restore blood flow through an artery that has become narrowed or blocked. Most often, the procedure is performed in an artery of the leg, where PAD is restricting circulation.
By improving circulation, peripheral artery angioplasty can help reduce PAD symptoms and improve walking ability. For a patient with more advanced disease, restoring blood flow can also promote wound healing, relieve pain caused by severely reduced circulation and help preserve the affected limb.
Peripheral angioplasty is one of several treatments available for PAD. Other options may include medication, management of cardiovascular risk factors, structured exercise therapy or open bypass surgery.
How Does Peripheral Angioplasty Improve Blood Flow?
During a peripheral angioplasty procedure, a vascular specialist will guide a thin catheter with a small balloon attached to the tip through an artery and navigate it to the area where blood flow is restricted. Once the balloon is properly positioned within the narrowed portion of the artery, the physician will inflate it. The inflated balloon will then press the plaque against the artery wall and expand the vessel, creating more space for blood to flow through. In some cases, the physician may also place a small mesh tube (stent) in the treated artery to hold it open and help maintain blood flow.
What Conditions Can Be Treated With Peripheral Angioplasty?
Peripheral angioplasty is most commonly used to treat peripheral artery disease, particularly when plaque buildup narrows or blocks arteries that supply the legs and feet. Depending on the severity of the circulation problem, PAD can cause symptoms ranging from leg discomfort with physical activity to pain at rest, nonhealing wounds and tissue damage.
For some patients, angioplasty for a blocked leg artery can restore enough blood flow to reduce symptoms and improve function. In more advanced PAD, improving circulation to the foot may also support wound healing and help reduce the risk of limb loss.
What Is the Relationship Between PAD and Leg Pain?
PAD develops when plaque accumulates in the peripheral arteries, reducing the amount of blood that can reach the muscles and other tissues. When the leg muscles need more oxygen during physical activity, the narrowed arteries may be unable to deliver sufficient blood to meet that increased demand.
As a result, peripheral artery disease may cause aching, cramping, heaviness, fatigue and other discomfort in the buttock, thigh, calf or foot during walking or other exercise. Collectively known as claudication, these symptoms typically improve after a period of rest.
Advanced PAD can cause pain even when the affected leg or foot is at rest. Severely reduced circulation can also contribute to wounds or ulcers that heal slowly or do not heal at all. When PAD causes persistent ischemic rest pain, nonhealing wounds or gangrene, the condition is known as chronic limb-threatening ischemia (CLTI). Prompt evaluation and treatment are important because CLTI can place the affected limb at risk.
When Is Peripheral Angioplasty Recommended?
Peripheral angioplasty may be recommended when PAD significantly reduces blood flow to a leg and revascularization is needed to improve circulation. The vascular specialist will determine whether angioplasty is appropriate after evaluating the patient’s symptoms, overall health, arterial disease and response to nonsurgical treatment.
For a patient with claudication, treatment may begin with medication to reduce cardiovascular and limb-related risks, structured exercise therapy and management of risk factors, such as smoking. If leg symptoms continue to significantly limit walking or other daily activities, revascularization with peripheral angioplasty or another procedure may be considered.
Angioplasty may also play an important role in treating CLTI. In this advanced form of peripheral artery disease, severely reduced blood flow can cause pain at rest, nonhealing wounds, ulcers or gangrene. Restoring circulation may help relieve ischemic pain, promote wound healing and preserve the affected limb.
Who May Be a Candidate for Peripheral Angioplasty?
Peripheral artery angioplasty may be considered if a vascular evaluation confirms that an arterial narrowing or blockage is contributing to significant symptoms or threatening the health of the limb. Angioplasty may be an option for a patient who has:
- Claudication that continues to significantly interfere with walking or daily activities despite appropriate medical treatment and structured exercise
- Ischemic pain in the foot or leg while at rest
- A nonhealing wound or ulcer associated with inadequate arterial blood flow
- Gangrene or other tissue damage caused by severely impaired circulation
While these symptoms may suggest that revascularization should be considered, they do not necessarily indicate that angioplasty is the most appropriate procedure. Some arterial blockages are better suited to another endovascular technique or open bypass surgery.
Balloon Angioplasty, Stenting and Bypass Surgery
Peripheral angioplasty is one of several procedures that can be used to restore blood flow to a leg affected by PAD. Depending on the location and characteristics of the arterial blockage, treatment may involve balloon angioplasty alone, angioplasty with stent placement or another endovascular technique. For some patients, open bypass surgery may be a better option. The goal is to select a treatment that can provide meaningful improvement in circulation while balancing the potential benefits, risks and durability of the procedure.
Is a Stent Always Needed During Peripheral Angioplasty?
No, a stent is not required during every peripheral angioplasty procedure. In some cases, inflating a balloon within the narrowed artery will provide an adequate result without placing a stent.
If the artery does not remain sufficiently open after balloon angioplasty or certain characteristics of the blockage make additional support beneficial, the vascular specialist may place a stent. This small mesh tube will remain inside the artery to help maintain blood flow through the treated area. The decision to use a stent will depend on the artery being treated and how the vessel responds to balloon angioplasty.
How Does Peripheral Angioplasty Compare With Bypass Surgery?
Peripheral angioplasty and bypass surgery are both forms of revascularization, meaning the procedures are performed to improve blood flow through arteries affected by PAD. The primary difference is how they accomplish that goal.
Peripheral angioplasty is an endovascular procedure. A vascular specialist will reach the diseased artery using a catheter inserted through a blood vessel, avoiding the larger incisions required for open surgery. As a result, angioplasty generally involves less physical stress on the body and a shorter initial recovery than bypass surgery.
Bypass surgery is an open procedure that creates a new route for blood to travel around a narrowed or blocked section of an artery, typically using a vein from the patient’s body or a synthetic graft. Although bypass is more invasive, it may be preferable for certain patients based on the location, extent and complexity of the arterial disease and other clinical factors.
Neither approach is best in every clinical scenario. Angioplasty may offer an effective, less invasive way to restore circulation in some cases, while the pattern or complexity of arterial disease may make bypass surgery more appropriate in others.
What Is Recovery Like After Peripheral Angioplasty?
Because peripheral angioplasty is performed through a catheter rather than a large surgical incision, recovery is generally shorter than after open bypass surgery. The patient may be able to return home the same day or after a brief hospital stay, depending on the extent of the procedure and the patient’s clinical needs.
After the procedure, the healthcare team will monitor the catheter insertion site and circulation in the treated leg. Some bruising, soreness or tenderness around the insertion site may occur. The patient will receive instructions on how to care for the treatment area, gradually resume normal activities and take any prescribed medications.
Many patients treated for claudication are able to walk with less discomfort after blood flow improves, although the degree and timing of symptom relief can vary. Continued walking and structured exercise may remain an important part of PAD treatment even after successful angioplasty.
Long-Term PAD Care After Angioplasty
Peripheral angioplasty can improve circulation through a narrowed or blocked artery, but it cannot cure PAD or the underlying atherosclerosis that causes plaque to accumulate in the arteries. Long-term care is important for maintaining vascular health, reducing cardiovascular and limb-related risks and identifying recurrent circulation problems.
After peripheral artery angioplasty, the patient’s care plan may include:
- Follow-up vascular evaluations – Periodic appointments and, when appropriate, vascular testing can help the healthcare team assess blood flow and monitor the treated artery.
- Medication management – The patient may receive antiplatelet therapy, cholesterol-lowering medication or other medications to reduce the risks associated with PAD and support long-term vascular health.
- Regular physical activity – Walking and other physician-recommended forms of exercise can help improve mobility and overall cardiovascular health.
- Smoking cessation – For a patient who smokes, quitting is one of the most important steps for slowing PAD progression and reducing cardiovascular and limb-related risks.
- Management of cardiovascular risk factors – Controlling conditions such as high blood pressure, high cholesterol and diabetes can help reduce the risk of PAD progression and other cardiovascular complications.
Even after a successful peripheral vascular angioplasty procedure, the treated artery may gradually narrow again, a process known as restenosis. PAD can also progress in other arteries. Ongoing follow-up will allow the vascular care team to monitor circulation and determine whether additional treatment is needed if symptoms return or new problems develop.
What Are the Risks of Peripheral Angioplasty?
Peripheral angioplasty is less invasive than open vascular surgery, but like any medical procedure, it has potential risks. The vascular surgery team will review these risks with the patient and take steps to reduce the likelihood of complications.
Possible risks of peripheral angioplasty include:
- Bleeding, bruising or swelling – Minor bleeding, bruising or swelling may develop at the catheter insertion site, although more significant bleeding can sometimes occur.
- Damage to the treated blood vessel – The catheter, balloon or other medical devices used during the procedure may injure the artery.
- Blood clots or arterial blockage – A clot can form within the treated artery or blood flow can become obstructed during or after the procedure, potentially requiring additional treatment.
- Contrast-related complications – The contrast material used to visualize the arteries during the procedure may cause an allergic reaction or affect kidney function in some patients.
- Restenosis or reocclusion – The treated artery can narrow again or become blocked over time, which may cause symptoms to return.
- Stent-related complications – When a stent is placed, complications such as narrowing or clot formation within the stent can occur.
Serious complications of peripheral angioplasty are uncommon, but additional endovascular treatment or bypass surgery may be necessary if angioplasty does not provide adequate blood flow, the treated artery narrows again or PAD progresses.
