What is the treatment for an arteriovenous fistula?
Less dangerous lesions may be simply observed and monitored. However, when there is evidence of brain swelling and venous aneurysms are present, the fistula should be treated. The main treatment method is endovascular surgery. During this procedure, the angiographer navigates a catheter into the arteries and veins in the head and precisely identifies the fistula. It is then obliterated using particles or glue. Occasionally, this treatment alone will not cure the fistula. Microsurgery (state-of-the-art surgery performed with specialized instruments and powerful microscopes) is then used to expose the fistula and disconnect the abnormal communication. At Lahey Clinic, we have extensive experience and worldwide recognition in treating these lesions. Our multidisciplinary cerebrovascular team evaluates each individual case. After careful consideration, an individualized treatment plan is developed.
