Endovascular occlusion of pial arteriovenous macrofistulae usingpCANvas1 and adenosine-induced asystole to control nBCAinjection

摘要

BackgroundIn large-caliber pial macrofistulae (pMF), the combination of high blood flow velocity and large efferent artery diameter makes control over the endovascular vessel occlusion difficult and may result in the inadvertent venous passage of occlusive devices or embolic agents.
