Spinal arteriovenous malformations: Is surgery indicated?

Spinal 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...

Parkes Weber syndrome and spinal arteriovenous malformations.

We read with great interest the article written by Alomari et al, and agree with the authors that Klippel-Trenaunay syndrome is not associated with spinal cord AVM. However, in their discussion, in relationship to spinal cord AVM with Parkes Weber syndrome, they comment briefly that “Spinal AVM has not been reported to be a feature of Parkes Weber syndrome.” Here, we demonstrate a case of Parke...

Embolization of spinal arteriovenous fistulae, spinal arteriovenous malformations, and tumors of the spinal axis.

Indications The indications for embolization of spinal cord AVMs include all symptomatic patients with lesions that can be cured; adjuvant therapy before surgery/radiosurgery; and palliative therapy when total obliteration is not practical and the patient suffers from progressive neurologic deficit or high risk of hemorrhage (associated aneurysm or pseudoaneurysm, previous hemorrhage) or when p...
