N eurosurgeons and neuroradiologists have tried different types of embolization to treat nonresectable cerebral arteriovenous malformations (AVM's). The variety of techniques used shows that there is no clear consensus about the best method of embolization. Luessenhop and his co-workers did pioneer work, and in 1960 published their first results of embolization of cerebral AVM's with plastic or steel emboli, 8 with a follow-up review 15 years later. 7 The factors governing successful embolization of cerebral AVM's with spheres or particles injected in the

C urrently available treatment options for cerebral arteriovenous malformations (AVMs) include observation, radiosurgery, and conventional surgery, the last two with or without endovascular treatment. Surgery provides an immediate cure with no threat of bleeding after a successful excision, although the risk of perioperative complications is relatively high. Radiosurgery is considered to be a relatively safe procedure, but there is still a significant risk of radiation necrosis. It also takes some time before the nidus is completely obliterated, and meanwhile

Interim report on the radiosurgical treatment of cerebral arteriovenous malformations

The influence of size, dose, time, and technical factors on obliteration rate

Yoshihiro Yamamoto, Robert J. Coffey, Douglas A. Nichols and Edward G. Shaw

R adiosurgery was first used to treat patients with cerebral arteriovenous malformations (AVMs) in Sweden in the 1970s. 13–15 Although some radiosurgical series have shown that obliteration rates were higher for small AVMs treated with 20 Gy or more to the margin, 1–4, 12, 13 other authors have reported nearly equal obliteration rates for medium-sized and larger lesions. 7, 9 We compared the angiographic obliteration rates, the time course of angiographic changes, and the clinical outcome in a series of radiosurgically treated patients with AVMs larger than

Cerebral arteriovenous malformations

Indications for and results of surgery, and the role of intravascular techniques

Alfred J. Luessenhop and Louis Rosa

D uring the past decade there has been greater interest in surgical management of cerebral arteriovenous malformations (AVM's) because of more frequent and earlier diagnosis, successful application of microsurgical techniques for deeper critically located lesions, continuing innovations in intravascular techniques, 2, 3, 5, 6, 10, 15, 28, 31, 36, 37 and better understanding of the anatomy and hemodynamics of these lesions. 14, 16, 20, 27, 29, 34, 38 However, important problems persist. These include the need for: 1) a more accurate formulation of the natural

I n 1960 a rationale for surgical embolization of certain inoperable cerebral arteriovenous malformations (AVM) was first described. We now use the term “surgical embolization” rather than the term “artificial embolization.” 14 We have used this technique, with slight modifications, for more than 15 years. 14 It became evident that many cerebral lesions also require embolization by way of the external carotid arteries; this experience encouraged us to extend the technique to include various vascular lesions and tumors located solely in the distribution of

T his study was undertaken to evaluate the usefulness of preoperative embolization in patients undergoing surgical resection of cerebral arteriovenous malformations (AVM's). The advent of microsurgical techniques has allowed neurosurgeons to undertake the resection of more formidable cerebrovascular malformations and has fostered the evolution of preoperative endovascular therapy. Endovascular embolization of cerebral AVM's is now an accepted adjunct to surgical therapy. However, the indications for endovascular therapy are still being clarified. The

I n a prior report based upon experience with over 250 cases, it was projected that approximately 50% of all cerebral arteriovenous malformations (AVM's) can be surgically obliterated or resected with a mortality and morbidity less than the natural course. 3 An additional 25% might be managed by an intravascular approach alone or combined with surgery, or, when the AVM's are small and deep, by irradiation alone. 1, 6 For the remaining patients, however, there has been no established treatment or proven effectiveness. Many of these heretofore untreatable

It is with great pleasure that we present this Neurosurgical Focus video supplement on supratentorial cerebral arteriovenous malformations (AVMs). We were privileged to view a remarkable number of outstanding videos demonstrating current state-of-the-art management of brain AVMs using endovascular and microsurgical modalities. Careful and critical review was required to narrow down the submitted videos to a workable volume for this supplement, which reflects the excellent work being done at multiple centers with these lesions.

This issue consists of videos that represent modern microsurgical and neuroendovascular techniques for the treatment of supratentorial cerebral AVMs. The videos demonstrate cutting-edge therapies as well as standard ones, which will be valuable to both novice and expert neurointerventionists and neurosurgeons. We are honored to be involved with this project and proud of its content and expert authors. We believe you will enjoy the video content of this supplement and hope that it will raise the collective expertise of our community of AVM surgeons.
