Do you experience severe pain in your legs, especially when you walk for a short distance? Does the pain subside after a while and then return when you walk? Or do you experience numbness in your legs, or slow healing after an injury? These are not symptoms to ignore. These could be caused by the gradual narrowing of the blood vessels in your legs. Today, we are talking about a treatment called 'Leg Revascularization'.
What is Leg Revascularization?
Simply put, this is to remove any blockage or blockage in the blood vessels (arteries) in your legs and allow blood to flow properly again. It's like cleaning out a clogged water pipe and allowing water to flow again.
The main cause of this condition is a condition called peripheral artery disease , or ``Peripheral Artery Disease (PAD)``. This is when fatty substances like cholesterol build up inside the blood vessels, gradually narrowing the blood flow. To treat this, doctors can use both endovascular procedures and open surgery.
What are these treatments?
The treatment method your doctor chooses may vary depending on your condition. There are several main methods used.
| Treatment method | Simply put, this is what happens. |
|---|---|
| Angioplasty | A small balloon is inserted into the blocked blood vessel and inflated. The blocked fat layer then presses against the wall of the vessel, widening the blood flow path again. |
| Placing a stent (Stent) | What is done in this is to place a small metal tube that looks like a mesh inside the vein after angioplasty to keep the vein from collapsing again. |
| Atherectomy | In this, a device with a blade or laser beam is passed through a small tube and scraped away the fatty layer (plaque) that has built up inside the artery. |
| Bypass surgery | Creating a new path for blood to flow around a blocked vein. This can be done using a vein taken from another part of your body or an artificial tube (graft). |
| Endarterectomy | This is a bit like an atherectomy, but what is done here is to cut the skin, take out the blocked blood vessel, and surgically remove the fatty layer inside it. |
Who needs this treatment?
Not everyone with PAD will need surgery. In the early stages, symptoms can be managed by quitting smoking, taking the medications your doctor prescribes, and walking daily .
However, if the symptoms are very severe, meaning you have leg pain even when you are standing, or if you have wounds in your leg that do not heal, we call that condition `(Critical Limb Ischemia)`. In such a case, surgery or the above-mentioned treatment is definitely needed. If not done, the blood flow to the leg may stop completely, and the leg may even have to be removed.
The most important thing is to see a doctor to find the exact cause, rather than assuming that leg pain is just a back problem.
How do you prepare before treatment?
Your doctor will discuss with you the best treatment option for you. This will depend on many factors, including the severity of your condition, the location of the blockage, and any other medical conditions you may have.
Before treatment, the doctor will examine you, ask about your medical history, and order some tests.
- Blood tests (Lab tests)
- Ultrasound scan `(Ultrasound)`
- ECG test (Electrocardiogram)
- CT angiogram `(Computed tomography (CT) angiogram)`
- MR angiogram `(Magnetic resonance angiogram)`
- Angiogram
You will be advised to stop eating and drinking a few hours before the treatment, usually after midnight. Also, stopping the use of tobacco products is very important for successful results. On the advice of your doctor, you may also need to temporarily stop taking some medications. Do not do any of these without your doctor's advice.
What happens after treatment and how long does it take to recover?
After the treatment, you will need to lie in bed for a few hours. The hospital staff will monitor you and give you any necessary medication. They may repeat the scans you did earlier to see if your veins have become blocked again.
The recovery time varies depending on the treatment you received:
- Angioplasty or atherectomy: After a minor procedure like this, you usually stay in the hospital for about a day and can fully recover in about a week.
- Bypass surgery: Since this is a major surgery, you will need to stay in the hospital for a few days. It can take about 6 to 8 weeks to fully recover.
Risk factors and when to see a doctor immediately
As with any medical treatment, there are some risks. For example, there is a small chance of bleeding, infection, blood clots, and heart problems. But these can often be controlled. Your doctor will explain all of this to you.
If you have any of the following symptoms, you should call your doctor immediately:
- The wound at the surgery site becomes infected or festering.
- Continuous bleeding.
- Redness, swelling, or extreme pain at the site of the wound.
- Fever or chills.
- Chest pain.
- Numbness or difficulty moving the treated leg.
The biggest benefit of these treatments is that your leg pain will be gone, your quality of life will improve, and you will be saved from the terrible risk of losing a leg.
Take-Home Message
- Pain when walking, numbness, and non-healing wounds in your legs can be symptoms of peripheral arterial disease (PAD). Don't ignore these.
- Leg Revascularization is a treatment that reopens blocked blood vessels and restores blood flow to the legs.
- To maintain long-term results after treatment, it is essential to completely quit smoking, control cholesterol, and exercise daily .
- Talk to your doctor about the best treatment for you and its risks. Don't hesitate to ask any questions.
