Endovascular procedures use minimally invasive, image-guided techniques that allow treatment to be delivered from within the blood vessels themselves. This minimally invasive approach carries lower surgical risk, shorter hospital stays, and faster recovery for many patients compared to traditional open surgery. Endovascular procedures are commonly used to treat conditions such as brain aneurysms, acute ischemic stroke, carotid artery disease, peripheral artery disease, deep vein thrombosis, and other complex vascular conditions where precision is critical.
Introduction to Endovascular Procedures
Endovascular procedures treat a wide variety of conditions and come in a variety of forms, such as angioplasty, stenting, thrombectomy, and embolization. Many patients now know to look for a vascular surgeon, but they may need a variety of specialists, including those who focus on these procedures.
Endovascular procedures are minimally invasive and image-guided, and are commonly considered for conditions such as:
- Brain aneurysm
- Acute ischemic stroke
- Arteriovenous malformation
- Carotid artery disease
- Abdominal aortic aneurysm
- Peripheral artery disease
- Deep vein thrombosis
- Varicose veins
- Recurrent TIAs
Patients are often nervous and uncertain about these procedures. Knowing what to expect will help.
Common Questions About Endovascular Treatment
What is endovascular treatment?
Endovascular treatment is a minimally invasive approach used to diagnose and treat conditions affecting the blood vessels. Using image guidance, specialists perform procedures through a small catheter inserted into an artery or vein in the groin or wrist, without the need for large surgical incisions or open surgery.
What conditions can be treated with endovascular procedures?
Endovascular treatment may be used for a range of vascular and neurovascular conditions, including brain aneurysms, stroke, peripheral arterial disease, aortic aneurysms, varicose veins, vascular malformations and certain causes of erectile dysfunction. The most appropriate treatment depends on the condition and individual patient factors.
Is endovascular treatment safer than open surgery?
For suitable patients, endovascular treatment may offer benefits such as smaller incisions, less discomfort and a shorter recovery period compared with traditional open surgery. However, the best treatment approach depends on the condition being treated, its complexity and your overall health.
How long does it take to recover after endovascular treatment?
Recovery varies depending on the procedure performed and your individual health. Many patients are able to return to normal daily activities sooner than after open surgery, although your specialist in Singapore will provide personalised advice based on your treatment and follow-up plan.
Who is suitable for endovascular treatment?
Suitability depends on the type of vascular condition, imaging findings, medical history and overall health. A specialist assessment helps determine whether an endovascular procedure is the most appropriate treatment option.
Before the Procedure: What to Expect
Before recommending treatment, specialists may first assess vascular health more broadly to identify any underlying conditions affecting the brain, neck, or circulation elsewhere in the body. You will start by having a consultation with a specialist, such as an endovascular specialist or vascular surgeon. They will go over your imaging, and may order additional tests to ensure a smooth procedure. They will discuss your options. You may also have tests to determine your suitability for surgery, such as an electrocardiogram.
Depending on the procedure, you may be going under general anesthesia or local/regional anesthesia and sedation. Your specialist will go over your medications; you may have to stop taking some, such as blood thinners, for a period of time before the procedure. You will also be advised on when to fast before the treatment, due to anesthesia.
During the Procedure: What Happens
You will need somebody to accompany you to your appointment. The surgeon will make a tiny incision, usually in the groin, and insert a catheter that will be moved through your circulatory system to the site of the problem. The surgeon will insert a stent, use a balloon to expand the vein, or perform another procedure designed to fix the problem. You will be under either general anesthesia or local anesthesia and sedation, depending on the procedure.
Patients often ask what safeguards are in place should an unexpected issue arise during treatment. Understanding how complications are managed can help patients feel more informed before undergoing a procedure.
After the Procedure: Immediate Recovery
Some people may need to spend the night, or even a couple of days in the hospital. Others may be released quickly. If you are going home the same day, you will need somebody to get you safely home. You may have to lie flat for a few hours.
Most patients are groggy until they fully recover from the anesthesia. The time this takes can vary from person to person. You're also likely to experience some fatigue. You should feel better within a few days, but may feel tired for a couple of weeks.
Recovery and Follow-Up
You will have a series of follow-up imaging appointments to track how your blood vessels are healing and ensure the endovascular procedure had the desired effect. It's vital to go to all of your follow-up appointments.
You should not shower for a few days, but should take sponge baths. Most people can return to all of their normal activities within four to six weeks. You may be able to go back to work sooner if your work is not physically demanding. Avoid strenuous exercise and sexual activity until cleared by your surgeon.
When to Discuss Endovascular Treatment Options with Your Doctor in Singapore
Endovascular treatment is not for everyone, but it is, when possible, better than surgery. It has less downtime, fewer risks, and fewer complications.
If you have been recommended surgery for a vascular problem, talk to your doctor about whether endovascular treatment will work for you instead. Endovascular surgery is particularly suitable for brain aneurysms without open surgery. For similar reasons, it is often an option for both ischemic stroke and recurrent TIAs (in order to avoid a stroke). Absolutely talk to your doctor if you are being told you are not a good candidate for surgery. Consider talking directly to an endovascular specialist in Singapore like Dr. Manish Taneja, for endovascular treatment options. Before any planned procedure, patients are usually encouraged to discuss treatment costs, insurance considerations, and other practical aspects of care including potential insurance, Medisave, and integrated shield plans that are accepted at our specialized vascular and interventional clinic.
Because endovascular treatment is used to manage a wide range of vascular and neurovascular conditions, the most appropriate treatment depends on your diagnosis, symptoms, imaging findings, and overall health.

Put Brain Aneurysm on Your Health Radar
Did you experience the worst headache of your life? Thoughts could be racing through your mind. A brain aneurysm is a weak spot in a blood vessel in the brain that can change over time. The key concern is when an aneurysm ruptures, which can disrupt blood flow, affect brain tissue, and lead to serious brain damage. Controllable conditions like high blood pressure can increase this risk and treatment options can depend on the condition. Surgical clipping is one option that prevents blood from entering the weakened area. In many cases, minimally invasive treatments can also be used to restore normal blood flow and reduce risk. We have created structured guides to help you explore each stage in more detail:
A simple (computed tomography) CT scan could be just what the doctor ordered and the first step in early detection and prevention of a brain aneurysm. Come in for an easy consultation with our brain aneurysm specialist in Singapore to be on your health radar.
