Application of the flow diverter stent was a safe and effective treatment with high success rate (96.3%) and low complication (3.7%).
A brain stent is a minimally invasive procedure that doctors use to treat brain aneurysms. Although the procedure is fairly new, there are generally good outcomes. One study using a specific type of stent showed that it fully diverted blood flow away from the aneurysm in 92.1% of people by 36 months after the surgery.
observed a 7.4% morbidity and 4.6% mortality in 216 patients treated with stents. In the series by Mocco et al. of 141 patients with 142 intracranial aneurysms underwent 143 stent deployments led to 5% technical complications. Procedure-related morbidity and mortality rates were 8.8% and 2%, respectively.
A previous study, the WEAVE trial, showed a low 2.6% stroke and death rate within the first few days of the procedure in patients received the Wingspan stent for intracranial atherosclerotic disease. The current study yielded a long-term 8.5% total one-year stroke and death rate.
General complications include infection, allergic reactions, stroke, seizure, and bleeding. Complications related to an endovascular procedure include: Blood clots: clots can form inside the catheter, on the coils or stents, or in the parent vessels.
Most patients who have cerebral angioplasty and stent are able to resume their normal activities within a few days to a week.
Rerouting the blood flow takes pressure off the aneurysm so it's less likely to rupture. In time, new cells grow on the stent, sealing the aneurysm and healing the vessel.
Along with these two critical components, follow your cardiologist's advice and take your prescribed medicines on time to manage your blood pressure, diabetes, and cholesterol. As a result, even after implanting stents in three major coronary arteries, if correctly controlled, you can live a long life.
Usually, patients stay overnight and return home the day after the procedure. Some may even go home the same day. The amount of time that you stay in the hospital will depend on if there were any difficulties during the procedure and how well the catheter insertion site is healing.
Stroke Safety
The latest study followed a group of stented patients for one year. The results showed a nearly 4% reduction in strokes and fatalities from a previous study using medical therapy alone, according to Michael Alexander, MD, director of the Cedars-Sinai Neurovascular Center.
One can go back to their normal routine within 2 to 3 days after undergoing the procedure, depending on the doctors' recommendations. However, patients who undergo this procedure must ensure they follow the above-mentioned lifestyle changes to lead a long and healthy life after stent placement.
artery wide open, you will need to have a follow up angiography test 6 months after placement. Further imaging is typically done after another 6 months with future studies considered at that time if needed. Having a stent does not create any complications with having X-rays, angio studies, or CT scans.
The short-term mortality rate is between 8.7% (one week after treatment, during the hospitalisation period), and 18.4% (after three months). One year after the vascular event, this figure reaches 22.9% and, five years later, 29%.
You will feel more tired than usual for several weeks after surgery. You may be able to do many of your usual activities after 4 to 6 weeks. But you will probably need 2 to 3 months to fully recover. For 6 weeks, it is important to avoid strenuous activity and heavy lifting.
The doctor may have placed a small tube, called a stent, in the artery. Your groin or wrist may have a bruise and feel sore for a few days after the procedure. You can do light activities around the house. But don't do anything strenuous until your doctor says it is okay.
Stent placement procedure
Typically, you're awake during your stent placement because it's a minimally invasive procedure.
Even though stents are generally safe to use, sometimes complications may occur during and after the stenting procedure. Complications are usually observed in people who have had previous surgeries to treat blocked arteries or who are affected with chronic diseases such as heart failure, kidney disease, or diabetes.
The results showed no difference in risk of heart attack or death compared to drug therapy, even for patients with severe ischemia.
As you get up after lying down, bring your head up slowly. This can prevent headaches or dizziness. You can wash your hair 2 to 3 days after your surgery. But do not soak your head or swim for 2 to 3 weeks.
Cognitive dysfunction is a frequent complication of an aneurysm or the surgery to repair it. The aneurysm and the surgery may cause physical changes to brain tissue and can lead to diffuse cognitive deficits, including problems with attention, memory, executive functioning, and information processing.
It will take 3 to 6 weeks to fully recover. If you had bleeding from your aneurysm this may take longer. You may feel tired for up to 12 or more weeks. If you had a stroke or brain injury from the bleeding, you may have permanent problems such as trouble with speech or thinking, muscle weakness, or numbness.
Most people with brain aneurysms do not have close family members with this condition. But a landmark study found that 1 in 5 people with a brain aneurysm has a family history of them.
