Introduction to Brain Aneurysm Flow Diversion with Stents

Brain aneurysms, also known as cerebral aneurysms, are potentially life-threatening medical conditions that demand immediate treatment when they occur. Aneurysm treatments have advanced significantly as medical science and technologies have improved. In previous decades, open surgery was a catch-all solution for all patients who needed attention. Now doctors can utilize minimally invasive procedures such as flow diversion and stenting to heal your body. This article will explain what these procedures entail, the recovery timeline after the surgery, and the potential risks of this approach.

What Do I Need to Know Before? 

A brain aneurysm is a weakness in the wall of a brain artery that causes a blood vessel to balloon or bulge. Unruptured brain aneurysms can lead to numbness, visual disturbances, numbness or pain on one side of your face, and a drooping eyelid. If the aneurysm is left untreated, the blood vessel can grow to press up on the surrounding areas of the brain or eventually rupture. This results in more severe issues such as intense headaches, extreme sensitivity to light, seizures, an altered mental state, neck stiffness, and a loss of consciousness.

The possibility of suffering from a brain aneurysm is impacted by several factors such as hypertension (high blood pressure), family history, smoking and drug use, age, gender, or a head injury. Doctors will conduct exams to assess the shape and location of the aneurysm. They may also put you on medication in preparation for the procedure.

Brain Aneurysm Flow Diversion Procedure

Flow diversion is a minimally invasive method of care in which a surgeon uses a catheter to place a stent (a flexible mesh tube) into the blood vessel where an aneurysm has formed without entering the aneurysm sac. A doctor makes an incision in your groin and puts the catheter through the cut. The catheter, which narrows the deeper it goes into your body, is guided towards the aneurysm with X-ray technology. The stent is available in a range of sizes depending on the size of the aneurysm.

Once the stent is in place, the blood flow is immediately rerouted away from the aneurysm. This removes pressure from the aneurysm, making it less likely to rupture. New cells will then grow on the stent, eventually sealing the aneurysm and healing the blood vessel.

Awareness Can Reduce Brain Aneurysm Fatalities

Your knowledge can be a lifeline. Discover how a heightened focus on brain aneurysms empowers individuals to recognize brain aneurysm symptoms before it’s too late.

Reasons For Having a Brain Aneurysm Flow Diversion Procedure

Flow diversion procedures are a preferable option for treating brain aneurysms because of these advantages over other surgeries:

  • Increased safety – Newer techniques in stents for endovascular methods means doctors do not have to enter the actual aneurysm. Since flow diversion doesn’t require this action, patients can have more confidence that there is a smaller chance of complications stemming from this surgery.
  • Shorter recovery – While other procedures result in lengthy recovery time, most patients who undergo flow diversion surgery can go home the next day and potentially return to their regular daily routine in a week.
  • Less recurrence – Flow diversion also results in a much lower chance of a patient developing another aneurysm. Reoperation rates are listed at about 3% in most studies.
  • Less radiation exposure – Patients receive a much higher dose of radiation from other treatment options than from a flow diversion procedure.
  • Lower costs – Lastly, flow diversion procedures are more affordable than other endovascular treatments.

 

Recovery After Flow Diverter Stent for Brain Aneurysm

After the procedure is finished, the patient is taken to a recovery room to monitor for potential side effects. Potential side effects may include:

  • A stroke
  • Bleed
  • Blood vessel damage
  • Visual problems
  • Cognitive issues
  • Headaches
  • Infections
  • Blood clots
  • Seizures
  • Coma

If you don’t have any side effects, you may be able to go home within a couple of days. It’s normal to have tenderness or bruising around the incision area. If you have excess pain after the procedure, your doctor may recommend some medication to provide relief.

Once you return home, it’s important to avoid exercising or lifting anything heavy until your doctor deems you physically ready to do so. You should also keep the catheter site as dry as possible and abstain from soaking it until it is healed. You can shower a day or two after the procedure, but pat the incision dry. Most patients can resume normal activities within a week of the procedure. Your doctor and medical team will monitor the aneurysm site regularly over the next year.

Flow Diverter Risks & Alternatives

Is a Flow Diverter Safe?

All surgical procedures confer some type of risk before but almost all aneurysms can be treated with endovascular approach previously not possible safely and effectively. Flow diverters have been proven to be safe ways to treat unruptured aneurysms of various sizes. Multiple studies show that major side effects are extremely rare, as are the chances of surgery-related death.

Why Do You Need a Brain Stent?

In addition to brain aneurysms, stents are also used for intracranial stenosis (a narrowing of blood vessels in the brain). The most common cause of this condition is atherosclerosis, a buildup of plaque in the arteries. If enough plaque blocks the artery, then a blood clot could develop and lead to a stroke.

Stents are not the only way to treat a brain aneurysm. Doctors could monitor the situation with medications for blood pressure, pain, or seizure prevention. More invasive treatments like endovascular coiling and surgical clipping are also available. Learn more in detail about other brain aneurysm treatment options. Endovascular surgery is far less invasive with faster recovery times and under interventional radiology, this is enabling quicker surgery and recovery time for many of today’s medical complications.

Put Brain Aneurysm on Your Health Radar

 

Did you experience the worst headache of your life? Could it be a brain aneurysm that ruptures, which means bleeding in the brain? Thoughts could be racing through your mind. Then what is the difference between unruptured (a weak or thin spot on an artery in the brain that balloons) or ruptured brain aneurysm? If you’re wondering, then the Supreme Vascular and Interventional Clinic is here to help. It’s important to look out for the tell-tale brain aneurysm symptoms, signs, causes, and risk factors.

Dr. Manish Taneja has been performing brain aneurysm treatments since 1995 from surgical clipping to latest minimally invasive procedures. Each patient is unique as is the size and location of the aneurysm. Your brain has different conditions to treat the aneurysm and artery vessel walls of a blood vessel in the brain. This calls for personalised brain aneurysm treatment depending on your symptoms, family, history, medication, and more. A simple 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.
