Peripheral Artery Disease (PAD) is a condition in which the blood vessels that supply blood to the legs or other parts of the body become narrowed or blocked. This condition is usually caused by the buildup of fatty plaque on the walls of the blood vessels, which hinders blood flow.
If left untreated, PAD can cause various symptoms, such as leg pain when walking, slow-healing wounds, and even serious tissue damage. One of the most common medical procedures to treat narrowing of the blood vessels in PAD is angioplasty.
What is Peripheral Artery Disease (PAD)?
Peripheral Artery Disease is a condition in which the arteries outside the heart and brain become narrowed. This narrowing restricts blood flow, which carries oxygen and nutrients to body tissues, especially the legs.
PAD often occurs due to the process of atherosclerosis , namely the buildup of plaque consisting of fat, cholesterol, and other substances on the walls of blood vessels.
Some risk factors that can increase the likelihood of someone experiencing PAD include:
- Diabetes
- High blood pressure
- High cholesterol
- Smoking habit
- Increasing age
PAD Symptoms to Watch Out For
In its early stages, PAD often doesn't cause any obvious symptoms. However, over time, some symptoms may appear, such as:
- Pain or cramps in the legs when walking (claudication)
- Feet feel cold or weak
- Changes in skin color on the feet
- Wounds on the feet that are difficult to heal
- Hair on legs decreases or falls out
If blood flow is further disrupted, this condition can increase the risk of tissue damage in the legs.
What is Angioplasty?
Angioplasty is a minimally invasive medical procedure performed to open narrowed or blocked blood vessels.
In this procedure, the doctor will insert a small catheter into the affected blood vessel. At the tip of the catheter is a small balloon that will be inflated at the narrowed area.
When the balloon expands, the plaque attached to the blood vessel wall will be pushed out so that the blood vessel becomes more open and blood flow can return to normal.
How is an Angioplasty Procedure Performed?
Angioplasty procedures are usually performed in a catheterization room or cath lab by an experienced specialist.
The general procedure steps include:
- The patient is given local anesthesia in the area of action.
- The doctor inserts a small catheter through a blood vessel, usually in the thigh or wrist area.
- With the help of special imaging, the doctor guides the catheter towards the location of the narrowing.
- Angioplasty balloons were developed to open narrowed blood vessels.
- In some cases, a doctor may insert a stent, which is a small, mesh-like tube that keeps the blood vessel open.
After the procedure is complete, blood flow is expected to return to normal.
Benefits of Angioplasty in PAD Cases
Angioplasty has several benefits in the treatment of peripheral artery disease, including:
- Opening narrowed blood vessels
- Improve blood flow to the legs
- Reduce pain when walking
- Helps speed up the healing of wounds on the feet
- Reduce the risk of more serious complications
Because it is a minimally invasive procedure, recovery time after angioplasty is usually relatively quicker than major surgical procedures.
The Importance of Early Detection and Treatment of PAD
Peripheral Artery Disease is a condition that can develop slowly. If not treated early, impaired blood flow can lead to serious complications in body tissues, especially in the legs.
Therefore, if you experience complaints such as pain in your feet when walking, cold feet, or wounds that are difficult to heal, you should immediately consult a doctor for further examination.
For a comprehensive examination and appropriate treatment, you can consult a specialist at EMC Alam Sutera Hospital. With comprehensive medical facilities and an experienced team of doctors, patients can receive optimal medical care for vascular diseases such as PAD.
