Introduction to Brain Aneurysms

A brain aneurysm is a bulge or ballooning in the wall of a blood vessel within the brain, occurring when the weakened vessel wall becomes stretched and dilated, creating a weak spot that leaks or ruptures over time. Because a brain aneurysm can cause life-threatening complications, including stroke, brain damage, and even death, timely treatment is crucial to help control bleeding and reduce the risk of rebleeding or complications.

Neurointerventional radiology represents a groundbreaking shift towards minimally invasive treatment of neurological conditions. In this article, we will cover how this specialty plays a vital role in saving lives and preserving brain function. This article is part of our guide to minimally invasive brain aneurysm treatment.

What is Neurointerventional Radiology?

Neurointerventional radiology serves as a less invasive alternative to traditional open surgery. This approach involves specialized imaging techniques such as angiography, CT, MRI, and small catheters to access the blood vessels and treat issues in the brain and spine. Patients experience shorter recovery times, fewer complications, and less pain.

Neurointerventional radiologists are trained in imaging and minimally invasive endovascular techniques. They complete a medical degree followed by a residency in either radiology or neurosurgery, and then a fellowship in interventional neuroradiology. With this, they can diagnose and treat a range of conditions within the central nervous system by using advanced imaging modalities to visualize the brain and spine. Procedures like catheter-based interventions are performed to treat conditions like aneurysms, stroke, and vascular malformations.

Why Neurointerventional Radiology Matters in Brain Aneurysm Treatment

Traditional Surgery vs. Endovascular Approaches

Neurointerventional radiology plays a crucial role in aneurysm treatment by offering minimally invasive endovascular approaches, making it an alternative to traditional surgery. With traditional surgical clipping, the skull is opened to access the aneurysm and clip it off from the blood supply. The technique is invasive, requires longer recovery times, and presents potential complications. Endovascular approaches, on the other hand, use catheters and specialized devices inserted through blood vessels to reach the aneurysm. Coiling is used to block off aneurysms from the blood supply and involves placing small coils within the aneurysm to clot it off and prevent future rupture. It is minimally invasive and less risky, with shorter recovery times and no large incisions.

Because of their minimally invasive nature, endovascular approaches are extremely valuable in ruptured aneurysms and hard-to-reach locations, and are generally considered safer.

Key Neurointerventional Procedures for Brain Aneurysms

There are several key neurointerventional procedures for brain aneurysms.

Endovascular Coiling

This minimally invasive procedure is used to block off blood flow to the aneurysm, and is commonly used for both ruptured and unruptured aneurysms. A catheter is threaded through an artery, then guided to the brain aneurysm. Once in place, tiny platinum coils are released into the aneurysm sac, which fills the aneurysm,  blocking blood flow and preventing rupture. Over time, scar tissue forms around the coils, which further stabilizes the aneurysm.

Flow Diverters

Flow diverters are a newer technology used for large, wide-necked, or complex aneurysms. These mesh-like stents are placed into the parent artery, redirecting blood flow away from the aneurysm, promoting clotting within the artery. As a result, the aneurysm shrinks over time. This procedure is commonly used for large, wide-necked, or complex aneurysms.

Stent-Assisted Coiling

This procedure combines coiling with a stent to support wide-necked aneurysms, and is a versatile approach for certain types of aneurysms. A stent is placed in the parent artery, acting as a scaffold to keep the coils from pushing into the artery. The stent helps to hold the coils in place within the aneurysm sac, making the coiling more stable and effective.

Balloon-Assisted Coiling and Intrasaccular Devices

Primarily used for treating wide-necked aneurysms, balloon-assisted coiling and intrasaccular devices can help prevent complications like coil herniation. They are designed to disrupt blood flow directly within the aneurysm sac, promoting clot formation and occlusion.

When is Neurointerventional Treatment Recommended? 

Neurointerventional treatment is recommended depending on a number of factors such as the aneurysm size, shape, and location, the patient's age, overall health, and whether the aneurysm is ruptured or unruptured. Treatment is usually considered when the risk of rupture outweighs the risk of intervention, or when the aneurysm is symptomatic.

Patients often compare minimally invasive techniques with traditional open surgery when exploring their options. Learn how these approaches differ and when each may be recommended. Not all brain aneurysms require immediate intervention, and treatment options are carefully selected based on individual risk assessment.

What to Expect During and After Treatment

The patient is placed under general anesthesia, and the hospital stay is shorter than open surgery. During the procedure, instruments and catheters are inserted through small incisions in your groin or wrist to access the blood vessels and reach the area needing treatment. X-ray imaging or other techniques may be used to guide the instruments and ensure accurate placement, and the length of the procedure will vary. Afterward, the patient will be monitored in a recovery area and, once stable, will be discharged. Post-procedure care may include rest, activity limitations, medication, and follow-up to ensure the aneurysm remains sealed. Afterward, the doctor will advise on returning to normal activities.

Advantages of Being Treated at a Specialized Brain Aneurysm Clinic 

At a specialized brain aneurysm clinic, patients have access to a full spectrum of care from neurointerventional radiologists and specialists. Dr. Manish Taneja is one of the few dual-trained and certified neurointerventional and peripheral vascular interventionists in practice in Singapore. Patients will receive comprehensive equipment for imaging and intervention, and personalized care plans and long-term monitoring.

Because these procedures require specialised training and experience, choosing the right doctor plays an important role in treatment outcomes. Learn how to evaluate your options and choose a specialist you can trust.

How Neurointerventional Radiology Saves Lives

Neurointerventional radiology significantly improves stroke outcomes and saves lives. According to studies, patients receiving timely treatment have a greater chance of independent functioning 90 days post-stroke in a significant portion of patients, significantly better than those treated with tPA alone, and patients have less risk of complications. 

Understanding who performs minimally invasive treatment is one part of the decision-making process. Learn how doctors decide between monitoring, minimally invasive treatment, and surgery.

Neurointerventional radiology is a powerful tool in modern brain aneurysm care, and everyone should ask questions and seek specialized help.  If you or a loved one has been diagnosed with a brain aneurysm, consult our brain aneurysm specialist, Dr. Manish Taneja, at our specialized brain aneurysm clinic in Singapore to explore safe, effective treatment options.

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.
