Inside your body, blood flows through tiny tubes called blood vessels. Sometimes, these tubes get all twisted and messy in one spot — that’s called an AVM, or Arteriovenous Malformation. It can cause problems, such as headaches or even bleeding, if not treated.
To fix it, doctors use a special method called Endovascular Embolisation. This method repairs the AVM from within the body, eliminating the need for large incisions.
First, the doctor helps you fall asleep so you won’t feel anything. Then, they gently slide a soft, thin tube into a blood vessel, usually in your leg. Using pictures on a screen, they guide the tube to the location of the AVM.
When the tube is in the correct position, the doctor inserts a small amount of special material, such as glue or soft plugs, to block the twisted vessels. This prevents blood from flowing in the wrong direction and helps prevent further complications. Once the AVM is blocked off, the doctor slowly removes the tube, and you rest in the hospital to recover.
This way, your blood flows more efficiently, and the risk of serious issues, such as bleeding, decreases.
Endovascular embolisation reduces blood flow to an AVM, which is an abnormal tangle of blood vessels in the brain or spinal cord. This helps prevent rupture or bleeding. It can be done alone or as prep for surgery or radiosurgery. The procedure lowers the risk of hemorrhagic stroke and neurological damage. It's essential if the AVM is deep, hard to reach, or considered high-risk.
Get medical help if you have ongoing headaches, seizures, sudden weakness, or unexplained neurological symptoms. An AVM might be discovered during imaging for other issues. If you are diagnosed, a neurosurgeon or interventional radiologist can determine if embolisation is suitable. Early treatment lowers the risk of severe bleeding or stroke.
Preparation involves detailed imaging of the brain, such as MRI, CT angiography, or cerebral angiogram, to identify the AVM’s size, location, and blood flow pattern. You may need to fast before the procedure and temporarily stop certain medications. Blood tests and an anesthesia evaluation will also take place. The care team will explain possible risks and get your informed consent.
During embolisation, a catheter is inserted through a small cut in the groin or wrist and guided to the AVM using imaging. A liquid embolic agent, like glue or Onyx, is injected to block the abnormal vessels. The aim is to slow or stop blood flow to the AVM. Afterwards, the catheter is removed, and a bandage is placed on the site.
The procedure usually takes 1.5 to 3 hours, depending on the complexity and location of the AVM. Most hospital stays last 1 to 2 days, but some patients may go home the same day. Doctors will monitor you for several hours after the procedure to check your neurological function. Recovery time varies based on your condition and the extent of treatment.
- Stroke or temporary neurological deficits
- Vessel rupture or bleeding
- Reaction to contrast dye or embolic material
- Infection or issues at the groin site
- Incomplete embolisation that may need follow-up treatments
- Lowers the risk of bleeding from the AVM
- Makes surgery or radiosurgery safer
- It is less invasive compared to open brain surgery
- Leads to shorter recovery times
- Can ease seizures or symptoms in some cases
Recovery requires rest and monitoring for signs of complications like headaches, weakness, or speech problems. Most patients can resume light activity within a few days, but follow-up imaging is necessary to confirm whether the embolisation was successful. Depending on treatment goals, further therapies like radiosurgery or repeat embolisation may be scheduled. Following post-op care is essential for better outcomes.
Success rates vary based on the AVM's size, location, and complexity. Embolisation alone cures AVMs fully in about 10 to 20% of cases, but it works very well when combined with other treatments. It significantly reduces the risk of bleeding and improves surgical outcomes. Advances in embolic materials and imaging techniques have led to increased success rates and enhanced safety over time.
