Treatment of Arteriovenous Malformations

At the outset, it must be stated that we can treat arteriovenous malformations very well and in the vast majority of cases, we can improve the quality of life of the patient significantly. Treatment will usually consist of embolization, surgery or a combination. Decisions are usually made by our multidisciplinary team.

Embolization is a procedure whereby, through an artery, a catheter is advanced until it reaches the site of the disease. At this point, a substance or particles are placed within the nidus or center of the AVM until the degree of shunting is reduced or it has been eliminated. Using percutaneous (across skin) access, substances can also be used to block the venous system of the AVM. This is usually followed within 24 – 48 hours by surgical resection.
