Aneurysm Stenting

Minimally Invasive Brain Aneurysm Treatment in New Jersey

When you’re diagnosed with a brain aneurysm, the news can feel overwhelming and frightening. An aneurysm is a weakened, bulging area in the wall of a brain artery that can potentially rupture, causing life-threatening bleeding in the brain. The good news is that modern medicine offers highly effective treatment options that can prevent rupture and protect your long-term health. 

At New Jersey Brain and Spine, our fellowship-trained neurointerventionalists specialize in advanced endovascular aneurysm repair, including aneurysm stenting — a minimally invasive technique that has revolutionized how we treat complex brain aneurysms.

Understanding Brain Aneurysms: Why Treatment Matters

A brain aneurysm forms when a weak spot in an arterial wall balloons outward, creating a thin-walled sac filled with blood. While many people live with unruptured aneurysms without knowing it, the critical concern is rupture risk. When an aneurysm ruptures, it causes subarachnoid hemorrhage, which can be fatal and cause permanent disability in many survivors.

Several factors influence rupture risk, including aneurysm size, location, shape, growth over time, family history or personal history of rupture, and lifestyle factors like smoking and uncontrolled hypertension.

The goal of treatment is to prevent rupture while preserving normal blood flow through the parent artery. This is where aneurysm stenting becomes a game-changer for many patients, particularly those with complex aneurysms that are challenging to treat with traditional methods.

What is Aneurysm Stenting?

Aneurysm stenting is a minimally invasive endovascular procedure that uses a specialized mesh tube (stent) to support the treatment of brain aneurysms. The stent is placed inside the parent artery across the aneurysm neck, where it serves multiple critical functions: providing structural support for coil placement in the aneurysm sac, redirecting blood flow away from the aneurysm, creating a scaffold that promotes healing and eventual sealing of the aneurysm, and preventing coils from protruding into the parent artery.

This neurointerventional surgery technique is performed through a catheter inserted into an artery, which is then navigated through the vascular system to reach the brain. Unlike traditional surgical clipping that requires opening the skull, aneurysm stenting is performed entirely from within the blood vessels, making it truly minimally invasive.

There are several types of stents used in aneurysm treatment, including conventional stents that provide support for coiling, flow diverter stents that redirect blood flow away from the aneurysm, and intracranial stents designed specifically for the unique characteristics of brain vessels. The choice of stent depends on your aneurysm’s specific characteristics and your individual anatomy.

Aneurysm Stenting: When is This Approach Right for You?

Not every aneurysm requires stenting, and determining the optimal treatment approach requires careful evaluation by experienced neurointerventional specialists. At New Jersey Brain and Spine, we use advanced imaging and multidisciplinary consultation to recommend the most appropriate treatment for each patient’s unique situation.

Ideal Candidates for Aneurysm Stenting Include:

• Wide-necked aneurysms: When the aneurysm neck (the opening into the aneurysm) is wide relative to the aneurysm dome, coils alone may protrude into the parent artery. A stent provides the support needed to keep coils safely within the aneurysm while maintaining normal blood flow.
• Complex aneurysm shapes: Aneurysms with irregular geometry, multiple lobes, or fusiform (circumferential) configuration often benefit from stent assistance during coiling or may be treated with flow diversion alone.
• Large or giant aneurysms: Aneurysms larger than 10mm (large) or 25mm (giant) may require stenting to achieve adequate treatment, as coiling alone might not provide sufficient aneurysm occlusion.
• Previously treated aneurysms: Aneurysms that have recurred or incompletely treated by previous coiling may benefit from stent-assisted re-treatment.
• Aneurysms at branch points: Some aneurysms occur where arteries branch, making treatment challenging. Stents can be positioned to preserve both branches while treating the aneurysm.

When Other Treatments May Be Preferred:

Surgical clipping may be better for certain aneurysms with favorable anatomy for open surgery, younger patients who want to avoid long-term antiplatelet medication, or cases where endovascular access is challenging. Simple coiling without stenting may be sufficient for small, narrow-necked aneurysms with favorable anatomy. Your neurointerventional team will discuss all options and recommend the approach that offers you the best chance for successful treatment with minimal risk.

The Aneurysm Stenting Procedure: What to Expect

Understanding the step-by-step process of aneurysm stenting can help reduce anxiety about the procedure. At our New Jersey practice, we perform these procedures in state-of-the-art neuroangiography suites equipped with the most advanced imaging technology.

Before the Procedure

You’ll undergo comprehensive imaging including high-resolution MRI, CT angiography, and diagnostic cerebral angiography to precisely characterize your aneurysm. Blood tests will assess kidney function and clotting ability. You’ll typically be started on antiplatelet medications (such as aspirin and clopidogrel) several days before the procedure to prevent blood clots from forming on the stent. Fasting for 6-8 hours before the procedure is required.

During the Procedure

The procedure is performed under general anesthesia in most cases, though some patients may have conscious sedation. The procedure typically takes a few hours depending on aneurysm complexity and anatomy. A catheter is carefully navigated through your arterial system up to the brain vessels.

Once positioned near the aneurysm, a microcatheter is advanced through the first catheter and guided precisely to the aneurysm location. The stent is then deployed across the aneurysm neck, expanding to fit the artery wall and create a supportive scaffold. If coiling is performed, another microcatheter is navigated through or alongside the stent into the aneurysm sac, and platinum coils are inserted to fill the aneurysm and promote clotting.

Throughout the procedure, continuous neuromonitoring and imaging ensure optimal stent placement and aneurysm treatment. 

Benefits of Minimally Invasive Brain Aneurysm Treatment

Aneurysm stenting offers significant advantages over traditional surgical approaches, making it an attractive option for appropriate candidates throughout New Jersey and beyond.

Key Benefits Include:

• Minimally invasive approach
• Typically shorter recovery time
• Reduced surgical trauma
• Access to deep or complex aneurysms 
• Lower complication rates for many aneurysm types

Understanding Risks and Potential Complications

Like all medical procedures, aneurysm stenting carries risks that must be carefully weighed against the risk of leaving the aneurysm untreated. However, when performed by experienced neurointerventionalists, serious complications are uncommon.

Potential Risks Include:

• Stroke
• Bleeding
• Contrast reaction
• Stent thrombosis
• Incomplete aneurysm treatment
• Artery injury or dissection

At New Jersey Brain and Spine, our complication rates are consistently below national averages, reflecting our team’s extensive experience and commitment to technical excellence in neurointerventional surgery.

Recovery and Aftercare: What Happens After Aneurysm Stenting

Recovery from endovascular aneurysm repair typically follows a predictable course, though individual experiences vary based on aneurysm complexity and whether complications occur.

Hospital Stay and Initial Recovery

Most patients remain hospitalized for a couple of days after aneurysm stenting for observation and neurological monitoring. During this time, you will be assessed regularly for any signs of complications, including changes in strength, sensation, vision, or speech. Your blood pressure will be carefully managed to optimize healing while protecting the treated aneurysm. 

Medication Management

Perhaps the most critical aspect of post-procedure care is antiplatelet therapy. You’ll typically take two antiplatelet medications (usually aspirin and clopidogrel) for a few months after stenting to prevent blood clots from forming on the stent. After this period, most patients continue aspirin indefinitely. Compliance with these medications is absolutely essential. 

Some patients also take medication to manage blood pressure, reduce headaches, or prevent seizures, depending on individual circumstances. Never adjust or stop any medications without consulting your neurointerventional team.

Activity Restrictions

For the first week after aneurysm stenting you may be instructed to avoid heavy lifting, strenuous exercise, or bending at the waist. Most patients can return to light work within a couple of weeks and resume normal activities including exercise after 2-4 weeks, with medical clearance. 

Follow-Up Imaging

Regular imaging is essential to monitor treatment success and detect any aneurysm recurrence early. This allows us to ensure the aneurysm remains adequately treated without requiring repeat catheter angiography in most cases. If concerns arise on non-invasive imaging, catheter angiography may be performed for more detailed evaluation.

Long-Term Lifestyle Considerations

Managing risk factors is crucial for preventing new aneurysms and protecting overall vascular health. This includes controlling blood pressure, quitting smoking (the most important modifiable risk factor), maintaining healthy cholesterol levels, managing diabetes, exercising regularly, and maintaining a healthy weight.

Many patients ask whether they can fly, undergo MRI scans, or pass through metal detectors after stent placement. Modern neurovascular stents are MRI-compatible and won’t trigger metal detectors. Air travel is generally safe once you’ve recovered from the procedure. Always inform medical professionals about your stent when undergoing imaging or other procedures.

If you have risk factors for aneurysms — including family history of aneurysms or subarachnoid hemorrhage, polycystic kidney disease, connective tissue disorders, or history of smoking and hypertension — discuss screening with your physician.

If you’ve been diagnosed with an unruptured aneurysm, prompt evaluation by a neurointerventional specialist is essential. While not all aneurysms require immediate treatment, expert assessment helps determine whether treatment is recommended and, if so, which approach offers you the best outcomes.

Warning signs that should prompt immediate medical attention include sudden, severe “thunderclap” headache (the worst headache of your life), neck stiffness, vision changes, loss of consciousness, seizures, nausea and vomiting with severe headache, or confusion and altered mental status. These symptoms could indicate aneurysm rupture and require emergency evaluation.
