We report on the predictors of seizure presention in unruptured brain arteriovenous malformations (AVMs). Between 1999 and 2008, 302 consecutive patients with AVMs were referred to our institution for endovascular treatment. Seventy-four patients (24.5%) experienced seizures without hemorrhage before treatment. We tested for statistical associations between angioarchitectural characteristics and seizure presentation. When we compared the 74 patients with seizures without hemorrhage with the 228 patients who did not experience seizures initially (total of 302 patients), male sex, cortical AVM location, AVM size of more than 3 cm, superficial venous drainage and presence of varices in the venous drainage were statistically associated with seizures (P=0.016, P=0.002, P=0.022, P=0.005, and P=0.022, respectively). Posterior fossa and deep locations and coexisting aneurysms were statistically associated with no seizures. The angioarchitectural characteristics of AVM associated with seizure presentation include male sex, cortical AVM location, AVM size of more than 3 cm, superficial venous drainage and presence of varices in the venous drainage.

Abstract Arteriovenous malformations (AVMs) of the brain represent unique challenges for treating physicians. Although these lesions have traditionally been treated with surgical resection alone, advancements in endovascular and radiosurgical therapies have greatly expanded the treatment options for patients harboring brain AVMs. Perhaps no subspecialty within neurosurgery has seen as many advancements over a relatively short period of time as the endovascular field. A number of these endovascular innovations have been designed primarily for cerebral AVMs, and even those advancements that are not particular to AVMs have resulted in substantial changes to the way cerebral AVMs are treated. These advancements have enabled the embolization of cerebral AVMs to be performed either as a stand-alone treatment, or in conjunction with surgery or radiosurgery. Perhaps nothing has impacted the treatment of brain AVMs as substantially as the development of liquid embolics, most notably Onyx and n-butyl cyanoacrylate. However, of near-equal impact has been the innovations seen in the catheters that help deliver the liquid embolics to the AVMs. These developments include flow-directed catheters, balloon-tipped catheters, detachable-tipped catheters, and distal access catheters. This article aims to review some of the more substantial advancements in the endovascular treatment of brain AVMs and to discuss the literature surrounding the expanding indications for endovascular treatment of these lesions.

Transvenous Approach

Ruptured cerebral arteriovenous malformations (AVMs) usually require treatment to avoid re-bleeding. Depending on the angioarchitecture and center strategy, the treatment can be surgical, endovascular, radiosurgical or combined methods. The classic endovascular approach is transarterial, but sometimes it is not always applicable. The transvenous approach has been described as an alternative for the endovascular treatment of small AVMs when arterial access or another therapeutic method is not possible. This approach can be considered when the nidus is small and if there is a single draining vein. We present a technical note on a transvenous approach for the treatment of a ruptured AVM in a young patient.

ABSTRACT:The common vascular anomalies of cerebral aneurysm and arteriovenous malformation may exist independently, or together as part of a closely related hemodynamic pairing. Resection or embolization of an AVM may be followed by a decrease in local blood flow, and lead to regression of a suitably situated proximal aneurysm. However, aneurysms located outside the angioarchitecture of the AVM, which remain flow-unrelated to the malformation, will likely not regress, and may in fact enlarge. Two cases are presented which demonstrate these vascular relationships, in order to better understand the regional hemodynamics of these anomalies prior to surgical or endovascular treatment planning.
