Vascular Procedures

Vascular procedures are minimally invasive treatments designed to improve blood flow in the arteries and veins.

They are performed to treat conditions such as blocked arteries, varicose veins, deep vein thrombosis (DVT), and pulmonary embolism, all of which affect how blood circulates between the heart and the rest of the body.

At TTLim Heart Clinic, our cardiologists perform a range of evidence-based vascular procedures using image-guided techniques that allow for faster recovery, smaller incisions, and less discomfort compared to traditional surgery.

When Are Vascular Procedures Needed?

Your doctor may recommend a vascular procedure if you experience:

Persistent leg pain, cramping, or swelling
Slow-healing wounds on your legs or feet
Varicose veins or visible enlarged veins
Shortness of breath or chest pain from a blood clot
Poor blood flow due to arterial blockage

These procedures aim to restore circulation, relieve symptoms, and prevent serious complications such as tissue damage or pulmonary embolism.

What Are the Common Vascular Procedures?

Endovascular Interventions

Endovascular procedures involve treating blocked or narrowed arteries from within the blood vessel using small catheters and imaging guidance.

They are often used for Peripheral Artery Disease (PAD) or arterial blockages in the legs, heart, or other organs.

Techniques such as angioplasty and stent placement help reopen the arteries and improve blood flow without open surgery.

Pulmonary Embolectomy

A pulmonary embolectomy is a specialised procedure performed to remove a blood clot (embolus) from the arteries of the lungs.

It may be performed surgically or through catheter-directed methods when a large pulmonary embolism threatens breathing or heart function.

This life-saving procedure restores normal blood flow to the lungs and helps stabilise circulation.

Radiofrequency Ablation (RFA)

Radiofrequency Ablation uses controlled heat energy delivered through a thin catheter to close off faulty veins, typically used in cases of varicose veins or chronic venous insufficiency.

The treated vein naturally seals and is reabsorbed by the body, allowing healthier veins to take over.

RFA offers a minimally invasive option with short recovery time and relief from leg pain and swelling.

Sclerotherapy

Sclerotherapy involves injecting a safe solution into small or medium-sized veins to close them off and reroute blood flow to healthier veins.

It is commonly used to treat spider veins and early varicose veins.

This quick, in-clinic procedure improves both leg comfort and appearance without surgery.

How Are Vascular Procedures Performed?

Most vascular procedures are image-guided, meaning they are done under ultrasound or fluoroscopy (X-ray) to ensure accuracy.

They are typically performed using:

Small catheters are inserted through a tiny skin puncture
Local anaesthesia or light sedation for comfort
Short recovery time, often allowing patients to go home the same day

Are Vascular Procedures Safe?

Yes. These procedures are considered safe when performed by experienced specialists. As with any medical treatment, your doctor will discuss potential risks and ensure that the benefits outweigh them based on your individual condition.

Frequently Asked Questions (FAQs)

1. Are vascular procedures painful? Most are minimally invasive and performed under local anaesthesia. Patients usually experience only mild discomfort, if any.

2. How long is the recovery time? Most patients return to daily activities within a few days, depending on the type of procedure performed.

3. Do I need hospital admission? Many procedures can be performed as day treatments, meaning you can go home on the same day.

4. Are these procedures permanent? Results are long-lasting when combined with healthy habits such as regular exercise, proper diet, and avoiding smoking.

5. Who performs vascular procedures at TTLim Heart Clinic? Our cardiologists are trained in both arterial and venous interventions, ensuring comprehensive care for heart and vascular conditions.
