“…Therefore, the space between the transverse processes is small, and the vertebral isthmus can appear like a straight fissure. 22,23 With the transverse approach, a reliable definition of the lamina, however, is the key for the localization of the zygapophyseal joint space and the adjacent neuroforamen. In contrast to this approach, our technique does not rely on depiction of the vertebral lamina but on the intertransverse ligament.…”

BACKGROUND AND PURPOSE:Injection therapies play a major role in the treatment of lower back pain and are to date performed mainly under CT or fluoroscopic guidance. The benefits of US-guided instillation procedures have been shown in many studies. We conducted this study to simplify an US-guided approach to the lumbar spinal nerves and to assess the feasibility and preliminary accuracy by means of CT and anatomic dissection.

“…This is provided by an anastomotic network formed by the anterior and posterior spinal arteries in the thoracolumbar region. 4 However, in the lower thoracic region the anterior spinal artery is less collateralized, and thus spinal cord blood supply is more dependent to the fl ow of the artery of Adamkiewicz. Furthermore, hypogastric blood fl ow deterioration can add to the development of spinal cord ischemia because of impairment of the artery of Adamkiewicz's perfusion.…”

“…A similar phenomenon could also have occurred in the perimedullary area or on the cord, as seen in Cases 2 and 3. Physiological arteriovenous shunts found in the cauda equina, which are thought to be a second-line venous drainage system, 29 have not been documented in cervical spinal nerve roots.…”

Object The authors previously reported a case of complex arteriovenous fistula (AVF) at C-1 with multiple dural and spinal feeders that were linked with a common medullary venous channel. The purpose of the present study was to collect similar cases and analyze their angioarchitecture to gain a better understanding of this malformation. Methods Three such cases, affecting 2 males and 1 female in their 60s who had presented with hematomyelia (2) or progressive myelopathy (1), were treated surgically, and the operative findings from all 3 cases were compared using digital subtraction angiography (DSA) to determine the angioarchitecture. Results The C-1 and C-2 radicular arteries and anterior and posterior spinal arteries supplied feeders to a single medullary draining vein in various combinations and via various routes. The drainage veins ran along the affected ventral nerve roots and lay ventral to the spinal cord. The sites of shunting to the vein were multiple: dural, along the ventral nerve root in the subarachnoid space, and on the spinal cord, showing a vascular structure typical of dural AVF, that is, a direct arteriovenous shunt near the spinal root sleeve fed by one or more dural arteries and ending in a single draining vein, except for intradural shunts fed by feeders from the spinal arteries. In 2 cases with hemorrhagic onset the drainer flowed rostrally, and in 1 case associated with congestive myelopathy the drainer flowed both rostrally and caudally. Preoperative determination of the shunt sites and feeding arteries was difficult because of complex recruitment of the feeders and multiple shunt sites. The angioarchitecture in these cases was clarified postoperatively by meticulous comparison of the DSA images and operative video. Direct surgical intervention led to a favorable outcome in all 3 cases. Conclusions A high cervical complex AVF has unique angioarchitectural characteristics different from those seen in the other spinal regions.
