Angioplasty and Stenting: Minimally Invasive Treatments for PAD

by | Jun 7, 2024

Minimally invasive methods of treatment, angioplasty and stenting, are popular and effective because they are effective as surgery with shorter recovery times for Peripheral Arterial Disease (PAD) patients. For a significant number of patients, this can be done as a day procedure with discharge from the hospital on the same day. Our clinic in Singapore offers comprehensive support for PAD  treatment options to improve mobility and well-being.

What is Peripheral Arterial Disease (PAD)?

PAD is the narrowing or blockage of arteries, simply put, a blocked leg artery. The condition primarily affects the legs and results in reduced blood flow. PAD can lead to pain in the legs, cramping and weakness. The disease is commonly caused when the buildup of cholesterol in the artery walls (atherosclerosis), which restricts blood flow. It is estimated that over 11% of Singaporeans are affected by PAD, which is well over half a million people.


What Are the Treatment Options for PAD?

Early Stage Treatments

Lifestyle changes and medications

Regular exercise and smoking cessation are crucial. Particularly, supervised exercise training can significantly improve PAD symptoms. Medications include statins, which lower bad cholesterol, reducing plaque buildup in the arteries. Also, blood pressure medications control hypertension and help maintain artery health.

Moderate to Severe PAD Cases

Angioplasty and Stenting

In angioplasty, the physician places a balloon-tipped catheter into the patient, which opens blocked arteries to improve blood flow. With stenting a mesh tube (stent) is deployed and remains in the artery to keep it open.

Both angioplasty and stenting are minimally invasive procedures. They involve shorter recovery times than bypass surgery.

Bypass Surgery

In bypass surgery, the physician removes a blood vessel from another part of the patient’s body and uses the transplanted vessel to bypass the patient’s blocked artery. This procedure is reserved for severe cases when other treatments would be ineffective. Again, the preferred, and least invasive treatment is peripheral arterial angioplasty.


What is Peripheral Arterial Angioplasty

Peripheral arterial angioplasty restores the blood flow restricted by narrowed arteries. The procedure is ideal for PAD patients who have symptoms of leg pain or wounds that have not healed. The goal is to alleviate the patient’s discomfort by improving blood circulation in the limb.

Who Needs Angioplasty?

Patients who experience severe PAD symptoms – persistent leg pain, limited mobility, or tissue death in the limb (ischemia) are the best candidates for angioplasty. Patients must consult a vascular specialist such as Dr. Manish Taneja to develop a personalized treatment plan.


Benefits of Angioplasty and Stenting

The three main benefits of the procedure are:

1. Symptom relief due to improved blood flow: This reduces the pain and cramping in the limbs.

2. Reduced Risk of complications: Angioplasty and stenting avoid the risks of limb amputation resulting from limb ischemia.

3. Shorter hospital stays: The procedure is minimally invasive, with faster recovery than bypass surgery.


The Procedure

In angioplasty and stent placement, the patient is sedated and the specialist threads a catheter to the affected artery.  A balloon within the artery inflates and widens the artery. A wire mesh stent can also be inserted to maintain the openness of the artery.

A needle-like long and thin tube (catheter) is inserted where the artery is blocked or narrowed. The photo shows a metal mesh tube called a stent.

Post-Treatment Recovery

With this procedure, patients can resume their normal activities within days. Patients must take the prescribed medications, and embark on and continue a healthy lifestyle with regular exercise, and blood pressure control.


Preventing Peripheral Arterial Disease

Follow these commonsense steps to prevent PAD:

1.  Practice self-care through regular exercise, cessation of smoking, and monitoring and controlling blood pressure.

2. Control the risk factors by monitoring blood pressure and cholesterol levels.

3. Have regular health checkups to identify PAD early.

4. Consult a healthcare professional for advice and treatment options when PAD is suspected. It is important to stay proactive in monitoring and managing vascular health.
