posterior cervical Spinal Cord Infarction following vertebral artery dissection
Neurology, 1997Co-Authors: Christina Bergqvist, H I Goldberg, Olafur Thorarensen, Shawn J BirdAbstract:There are only two reported cases of unilateral posterior cervical Spinal Cord Infarction as a result of vertebral artery dissection. We describe the first reported case of bilateral posterior Spinal Cord Infarction caused by vertebral artery dissection.

cervical Spinal Cord Infarction after cervical spine decompressive surgery
World Neurosurgery, 2014Co-Authors: Samuel Kalb, Saeed Fakhran, Bruce L Dean, Jeffrey S Ross, Randall W Porter, Udaya K Kakarla, Paul Ruggieri, Nicholas TheodoreAbstract:Objective To report five patients who underwent cervical decompressive surgeries and developed persistent postoperative neurologic deficits compatible with Spinal Cord Infarctions and evaluate causes for these rare complications. Methods The clinical courses and imaging studies of five patients were retrospectively analyzed. Imaging findings, types of surgeries, vascular compromise or risk factors, hypotensive episodes, intraoperative somatosensory evoked potentials, concomitant brain Infarctions, and clinical degree and radiographic extent of Spinal Cord Infarction were studied. The presence of Spinal Cord Infarction was determined by clinical course and imaging evaluation. Results All five patients had antecedent cervical Cord region vascular compromise or generalized vascular risk factors. Four patients developed hypotensive episodes, two intraoperatively and two postoperatively. None of the four patients with hypotensive episodes had imaging or clinical evidence of concomitant brain Infarctions. Conclusions Neuroimaging evaluation of Spinal Cord Infarction after decompressive surgery is done to exclude Spinal Cord compression, to ensure adequate surgical decompression, and to confirm Infarction by imaging. Antecedent, unrecognized preoperative vascular compromise may be a significant contributor to Spinal Cord Infarction by itself or in combination with hypotension.

a case of Spinal Cord Infarction following lumbar transforaminal epidural steroid injection mr imaging and angiographic findings
American Journal of Neuroradiology, 2009Co-Authors: E M Lyders, P P MorrisAbstract:SUMMARY: Spinal Cord Infarction following lumbar transforaminal epidural steroid injection is a rare and devastating complication. We describe the case of a 55-year-old woman who developed Spinal Cord Infarction following right L2-3 transforaminal epidural injection, diagnosed on the basis of clinical and MR imaging findings. Spinal angiography demonstrated occlusion of the right L2 segmental artery with reconstitution of the radicular branch from collaterals. The artery of Adamkeiwicz could not be demonstrated and was presumably occluded by the steroid injection.

hemi Spinal Cord Infarction due to vertebral artery dissection in congenital afibrinogenemia
Neurology, 2004Co-Authors: Helmut Laufs, S Weidauer, C Heller, M Lorenz, Tobias NeumannhaefelinAbstract:Isolated ischemia of the cervical Spinal Cord is an uncommon but increasingly recognized complication of vertebral artery dissection (VAD). The authors report a young patient with congenital afibrinogenemia, who developed VAD with extensive unilateral Spinal Cord Infarction, probably caused by local compression of Spinal radicular feeders at their origin by vertebral artery hematoma.
