Embolization of intramedullary arteriovenous malformations of the spinal cord.
Intramedullary spinal cord arteriovenous malformation (AVM) can be a devastating disease. It is not usually amenable to surgery without producing severe neurologic deficit. Previously, the risk of cord ischemia was considered a contraindication to therapeutic embolization. Three patients with intramedullary spinal cord AVMs were examined and treated using polyvinyl alcohol foam, mixed with Gelf...
متن کاملElectrophysiological signs of arteriovenous malformations of the spinal cord.
A characteristic pattern of electrophysiological changes was found in 24 patients with confirmed spinal cord arteriovenous malformations (AVMs). The AVMs were limited to the thoracic cord in seven, involved the conus and the cauda equina in 10, and involved all levels in six. Of the patients, 88% had at least one definite electrophysiological abnormality: nerve conduction studies showed abnorma...
متن کاملSpinal arteriovenous malformations.
Spinal arteriovenous malformations originate probably by a detention in the normal evolution of the embryonic vessels. By unknow reasons, and about the end of the first month of the embryonic life, the normal differentation toward arteries, veins and capillaries fails, and non-differentiated vesseIs persist in the adult life, mantaining the anatomic and physiologic characteristics of the embryo...
متن کاملSpinal arteriovenous metameric syndrome: angioarchitecture and their prognosis.
The term “spinal arteriovenous metameric syndrome” (SAMS) is relatively new and is derived from craniofacial arteriovenous metameric syndrome (CAMS), which was introduced to designate a rare form of vascular malformation involving both brain and face. SAMS includes all spinal vascular malformations of nonhereditary genetic metameric origin, affecting not only the central nervous system (spinal ...
متن کاملSpinal arteriovenous metameric syndrome: clinical manifestations and endovascular management.
BACKGROUND AND PURPOSE SAMS is a rare form of SCAVM. We discuss the clinical presentation, endovascular management, and outcome of this disease in our series. MATERIALS AND METHODS Retrospective review was performed in patients with SCAVM and SAMS who underwent angiography with intent to treat at our institution from 1980 to 2010. RESULTS One hundred forty-eight SCAVMs were identified, and ...
