PAD is a circulatory disorder that affects the peripheral arteries, usually those of the limbs, particularly the legs, due to the constriction of these arteries. Among the treatment options for PAD, angioplasty is one of the most efficient. This non-surgical procedure helps to widen blocked or constricted arteries to allow blood to flow to the parts of the body affected by PAD, which makes it a viable treatment for this disease.

How Does Angioplasty Work?

• Preparation: The angioplasty procedure starts with positioning of the patient to ensure comfort and reduce pain as much as possible. Before the catheter is inserted, the patient is given a local anaesthetic to prevent any discomfort in the area where the catheter will be inserted which is mostly the groin. Sedation may also be administered to ensure that the patient does not get agitated during the process.
• Catheter Insertion: After the patient has been positioned appropriately, the doctor then takes a small cut on the artery and then guides a catheter, which is a thin and flexible tube, into the artery. Fluoroscopy is a real time X-ray imaging technique and the catheter is introduced through the arterial system and the doctor can then locate the blockage properly.
• Balloon Inflation: Once the catheter is in position at the site of the obstruction a small balloon on the tip of the catheter is inflated. The balloon inflates and pushes against the walls of the artery and compresses the plaque (fatty deposits) and expands the artery to allow better blood circulation. This step is essential for the alleviation of the symptoms of PAD and the achievement of satisfactory blood flow to the affected extremity.
• Stent Placement (if needed): Sometimes, a small wire mesh tube called a stent may be inserted into the artery to help keep it open. It is usually mounted on the balloon and when the balloon is inflated the stent also expands. After the artery is enlarged, the balloon is deflated and pulled out, but the stent stays in the artery permanently to keep the artery from becoming narrow again.
• Completion: Once the balloon is deflated, and the catheter is withdrawn, the wound is then closed with sutures or sealed. The patient is observed for a while to check for any adverse effects before the patient is discharged. This observation period is important to safeguard the life of the patient as well as the success of the procedure.

Benefits of Angioplasty

Angioplasty offers several advantages for treating PAD:

• Minimally Invasive: Angioplasty does not involve large incisions like open surgery and therefore has little scarring, less chances of infection, and the patient can be discharged earlier. This minimally invasive procedure makes it a procedure that many patients would prefer over other procedures.
• Effective Relief of Symptoms: Angioplasty can help to reduce or erase the pain of PAD, including pain during walking (intermittent claudication), thus improving the patient’s quality of life and his/her ability to perform routine tasks.
• Quick Recovery: Patients are usually advised to be up and about within a few days to weeks after angioplasty, not like the open surgery that may take several weeks to heal. One of the advantages of using it is that there is a quick return to normalcy for those who do not wish to spend much time off.
• Immediate Results: Angioplasty can reopen the blocked arteries and improve symptoms within a few minutes to a couple of hours. Such a rate of improvement is vital for patients with severe manifestations or those with critical limb ischemia, where the blood flow should be restored as soon as possible to avoid tissue necrosis.

Recovery

Recovery from angioplasty is generally straightforward, but it’s essential to follow your doctor’s instructions to ensure the best outcomes:

• Immediate Aftercare: As for the postoperative care, you will be observed for several hours to rule out any complications. A sterile dressing will be placed on the area of the incision and you may be asked to lie still for a few minutes while the artery starts to heal.
• Discharge Instructions: Your doctor will provide instructions on how to care for the incision site, manage pain, and recognize signs of complications. It is common to be prescribed analgesics for pain relief and anticoagulants to prevent blood clots.
• Follow-Up Care: Regular follow-up appointments are essential to monitor the effectiveness of the angioplasty, assess healing progress, and manage any risk factors for PAD. Your doctor will also advise on lifestyle changes to prevent further blockages and maintain the benefits of the procedure.
• Activity Restrictions: While you can usually walk and engage in light activities soon after angioplasty, it is important to avoid strenuous activities and heavy lifting until cleared by your doctor. Overexertion can interfere with the healing process and increase the risk of complications.

Lifestyle Modifications

To sustain the benefits of angioplasty and prevent the progression of PAD, adopting a heart-healthy lifestyle is crucial. This includes:

• Smoking Cessation: Quitting smoking is vital, as smoking is a significant risk factor for PAD and can counteract the benefits of angioplasty.
• Healthy Diet: Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help control cholesterol levels and improve overall cardiovascular health.
• Regular Exercise: Engaging in regular physical activity can improve circulation, strengthen the cardiovascular system, and maintain the benefits of the procedure.
