Endovascular embolization of the swine rete mirabile with Eudragit-E 100 polymer.
BACKGROUND AND PURPOSE Both adhesive and nonabrasive embolic agents are available for arteriovenous malformation (AVM) embolization. The purpose of this study was to evaluate a novel ethanol-based nonadhesive liquid embolic material in a swine AVM model. MATERIALS AND METHODS Eudragit (copolymer of methyl and butyl methacrylate and dimethylaminoethyl methacrylate) was dissolved in 50% ethanol...
متن کاملEndovascular Embolization of Brain Arteriovenous Malformations with Eudragit-E
Eudragit-E was originally developed as a non-adhesive liquid embolic material in the late 1990s and is a copolymer of methyl and butyl methacrylate and dimethylaminoethyl methacrylate that is dissolved in ethanol and iopamidol. This material has been used for endovascular embolization of brain arteriovenous malformations (AVMs) for some time but is currently not widely used. Because safety and ...
متن کاملCarotid rete mirabile associated with subarachnoid hemorrhage.
A 47-year-old man presented with carotid rete mirabile manifesting as subarachnoid hemorrhage (SAH). Computed tomography showed SAH, and angiography disclosed an abnormal vascular network around the petrous and cavernous portions of the internal carotid artery. Single photon emission computed tomography (SPECT) with technetium-99m methyl cysteinate dimer revealed reduced regional cerebral blood...
متن کاملCollagen microbeads: experimental evaluation of an embolic agent in the rete mirabile of the swine.
PURPOSE To evaluate the histologic and angiographic effects of collagen microbeads as an embolic agent in the swine rete mirabile. METHODS Human collagen particles (380 +/- 100 microns) of spheroidal shape and smooth surface were used to embolize the rete mirabile in five swine. Control angiograms and pathologic examinations were obtained immediately and sequentially from 3 to 35 days after e...
متن کاملA pediatric case of carotid rete mirabile.
BACKGROUND Carotid rete mirabile (CRM) is a physiological network between the external carotid and internal carotid systems in lower mammals. Very rarely, these arterial channels are observed in humans. CASE DESCRIPTION We describe a 13-year-old girl with CRM who presented with acute hemiplegia after an operation for Dieulafoy's ulcer, a submucosal vascular anomaly of the stomach. Angiogram r...
