How long is the recovery time after embolization?

Recovery varies but is generally quicker than traditional surgery, with most patients returning to normal activities within a few days to weeks.

Will I need to stay in the hospital after the procedure?

Typically, a short hospital stay is required for monitoring, often 1-2 days.

What is AVM embolization?

AVM embolization is a minimally invasive procedure where a special glue-like substance or particles are injected into the AVM's feeding arteries to block blood flow and shrink or eliminate the malformation.

Why is AVM embolization performed?

AVM embolization is performed to reduce the risk of bleeding (hemorrhage), seizures, stroke, and other neurological problems associated with AVMs. It can be used alone or as a pre-treatment before surgery or radiation therapy.

How is AVM embolization performed?

A catheter is inserted into an artery (usually in the groin) and guided to the AVM's feeding arteries using real-time X-ray imaging (angiography). Embolic material is then injected to block the abnormal connections.

What are the risks of AVM embolization?

Risks include stroke, bleeding, infection, allergic reaction to contrast dye, groin hematoma, vasospasm, and neurological deficits. The risk level varies depending on the AVM's size, location, and the patient's overall health.

How do I prepare for AVM embolization?

Preparation typically involves a physical exam, blood tests, imaging scans (MRI/CT scan), and potentially stopping certain medications (like blood thinners). You will need to fast before the procedure and follow specific instructions from your doctor.

What can I expect after AVM embolization?

After embolization, you'll typically stay in the hospital for observation. You may experience pain or discomfort at the catheter insertion site or related to the embolization. Follow up imaging is usually schedule to evaluate the results

How effective is AVM embolization?

The effectiveness of AVM embolization varies depending on the AVM's characteristics. In some cases the AVM can be fully removed and in other repeated embolizations may be needed. It is often effective in reducing the size of and the risk of rupture.

Are there alternatives to AVM embolization?

Alternatives to AVM embolization include microsurgical resection (surgical removal), stereotactic radiosurgery (radiation to shrink the AVM), and conservative management (monitoring without intervention), depending on the specific AVM.

Transforming Lives with Embolization of AVM

Embolization is a minimally invasive procedure used to treat arteriovenous malformations (AVMs), which are abnormal tangles of blood vessels connecting arteries and veins. This treatment involves inserting a catheter into the blood vessels leading to the AVM and injecting materials to block the abnormal vessels. The primary goal is to reduce blood flow to the AVM, alleviate symptoms, and prevent complications such as bleeding or stroke. Embolization can be used alone or in conjunction with other treatments like surgery or radiosurgery.

The typical steps involved in Embolization of AVM

Consultation and Imaging: Initial assessment with MRI or angiography to locate the AVM.
Anesthesia: Patient is given local or general anesthesia.
Catheter Insertion: A catheter is inserted through a small incision, usually in the groin.
Guidance to AVM: The catheter is guided to the AVM using imaging techniques.
Embolic Agent Injection: A material (glue, coils, particles) is injected to block the abnormal vessels.
Monitoring: Continuous monitoring to ensure the AVM is adequately treated.
Post-Procedure Care: Observation and follow-up imaging to check for success and monitor for complications.
