Vascular malformations and hemangiomas of the canine spinal cord.
An arteriovenous malformation and two hemangiomas in the canine spinal cord were found in three dogs. The malformation was ventral, extramedullary and largely subdural. Chronic hypoxia, consequent upon the shunt, had led to extensive local edema, necrosis and hemorrhage at T13-L1. Prominent intramedullary perivascular fibrosis, mineralization and obliteration were the presumed consequences of t...
متن کاملSpinal vascular malformations
• Vascular supply of the spinal cord is by anterior spinal artery in the median fissure and 2 posterior spinal arteries supplemented by medullary branches of intervertebral artery. The intervertebral artery gives s dural and medullary branches. The dural branches persist through life, however, the majority of medullary arteries involute and by adult life only 6-10 medullary arteries persist. Th...
متن کاملEmbolization of spinal cord vascular malformations via the anterior spinal artery.
During a 3 year period, 21 patients with spinal cord vascular malformations involving the anterior spinal artery were treated by embolization through this artery. Of four cases of extramedullary arteriovenous fistula, two patients embolized at an early stage showed excellent results, whereas results were mediocre in two patients who were paraplegic at embolization. Of 17 cases of intramedullary...
متن کاملMR angiography of spinal vascular malformations.
PURPOSE To determine the potential and limitations of MR angiography in the evaluation of spinal vascular malformations. METHODS Eleven consecutive patients with spinal vascular malformations proved with spinal selective arteriography underwent two-dimensional phase-contrast MR angiography. RESULTS Abnormal vessels within the spinal canal were identified with MR angiography in 10 patients. ...
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...
