Arteriovenous malformations (AVMs) are improper artery-to-vein connections, usually in the brain or spine. The surgery requires making a small incision near the AVM, sealing the surrounding arteries and veins to prevent bleeding, and then surgically removing the AVM.
Your health care physician will assess your symptoms and perform a physical exam to determine if you have a brain AVM. Visit the best multispecialty hospital in Yeshwanthpur for tests and diagnosis.
Diagnosis of Arteriovenous malformations (AVMs)
AVM in the brain can be diagnosed using one or more tests. Neuroradiologists typically perform imaging examinations. There are various possible treatments for brain AVM. The primary goal of treatment is to prevent haemorrhage, but seizures and other neurological consequences may also be addressed.
The best treatment for your illness is determined by the age, health, and the size and location of the brain AVM. Pharmaceuticals may be used to treat AVM-related symptoms such as headaches or seizures.
Treatments and Procedure
There are mainly three methods of surgery that are adopted in such scenarios-
If the AVM in the brain has bled or is in an easily accessible location, brain surgery to remove the AVM may be advised. In this treatment, the surgeon temporarily eliminates a portion of the skull to allow access to the AVM.
The doctor seals the AVM with special clips and carefully separates it from surrounding brain tissue using a high-powered microscope. The surgeon next reconnects the skull bone and closes the scalp incision.
Resection is usually performed when the AVM can be removed without causing bleeding or seizures. AVMs in deep brain regions are more likely to cause difficulties. In certain circumstances, your doctor may suggest alternative therapy. Looking for Arteriovenous Malformation (AVM) surgery Treatment in Yeshwanthpur, visit Manipal Hospitals.
Endovascular embolization (EVE)
A catheter is placed into an artery in the leg or wrist and threaded through blood arteries to the brain using X-ray imaging in this technique.
The catheter is inserted into one of the arteries feeding the brain AVM. To block the artery and restrict blood flow into the AVM, the surgeon injects an embolising agent, such as tiny particles, a glue-like substance, microcoils, or other materials.
Endovascular embolization is less invasive than traditional surgery. It can be done on its own. However, it is frequently used before other surgical procedures to make them safer. It accomplishes this by lowering the size of the brain AVM or the risk of bleeding.
Radiosurgery with stereotactic accuracy (SRS)
This procedure destroys the AVM with precisely focused radiation. Because there are no incisions into the body, it is not surgery in the traditional sense.
SRS, on the other hand, directs a large number of highly targeted radiation beams at the AVM in order to damage the blood vessels and create scarring. Following therapy, the scarred AVM blood vessels gradually clot off over 1 to 3 years.
This technique is best suited for small AVMs that are difficult to remove with traditional surgery and have not produced a life-threatening bleed.
