It contributes to the posterior spinal artery. (lecturio.com)
And, to boot, there is a large posterior spinal artery coming off from left T8, across from fistula. (neuroangio.org)
More complex fistulas can have both anterior spinal and posterior spinal artery supply, such as this diagram below. (neuroangio.org)

Anterior cord syndrome can be caused by occlusion of the anterior spinal artery or by trauma, which results in disc herniation and bone fragments disrupting the spinal cord. (lecturio.com)
In the recently published case report by Haynes et al, intraarticular thrombolysis with tissue plasminogen activator (t-PA) in combination with verapamil and an antiplatelet agent (Eptifibatide) was performed for acute occlusion of the anterior spinal artery in a 52-year-old patient. (fortunejournals.com)

It arises from branches of the vertebral arteries and courses along the anterior aspect of the spinal cord. (wikipedia.org)

The anterior spinal artery arises bilaterally as two small branches near the termination of the vertebral arteries. (wikipedia.org)
Blood flows from the anterior spinal artery into medullary branches of the intradural vertebral arteries, and subsequently into segmental radiculomedullary arteries. (medscape.com)
The blood flow to the posterior spinal arteries originates from intradural vertebral arteries, which are from medullary segments of the posterior inferior cerebellar arteries and segmental radiculopial arteries. (medscape.com)

It is a radicular artery that contributes to the anterior spinal artery below T8. (lecturio.com)
The radicular LBP caused by spinal stenosis is probably related to the inhibition of normal nerve root vascular flow with resultant nerve root nutrition, nerve root edema, and nerve root dysfunction. (medscape.com)
In summary, clinical practice and animal research suggest that radicular pain is the result of inflammation of the nerve root in the epidural space provoked by leakage of disk material, compression of the nerve root vasculature, and/or irritation of dorsal root ganglia from spinal stenosis. (medscape.com)
Blood flow to the lower portion of the spinal cord (T8-L3) is supplied by a large radicular artery with somewhat variable positioning, termed the Artery of Adamkiewicz. (medscape.com)
Up to eight radicular arteries are established during development and supply the anterior spinal artery, the largest of which is the artery of Adamkiewicz between T9 and T11. (biomedcentral.com)
Mid-thoracic levels are most vulnerable to ischemia (for example, as a result of thrombosis) as there is only one radicular artery supplying the anterior spinal artery in this region, and sparse anastomoses. (biomedcentral.com)
Pathophysiologically, sDAVFs are characterized by a low-flow abnormal connection between an anterior or posterior radiculomeningeal arterial branch and a medullary or radicular vein. (neurosurgicalatlas.com)

Hematomyelia more commonly involves the cervical rather than thoracic or lumbar spinal cord. (medscape.com)
The anterior spinal artery has only a few feeder arteries in the upper cervical region and one large feeder (the artery of Adamkiewicz) in the lower thoracic region. (msdmanuals.com)
Because collateral circulation for the anterior spinal artery is sparse in places, certain cord segments (eg, those around the 2nd to 4th thoracic segments) are especially vulnerable to ischemia. (msdmanuals.com)
Note that the spinal cord level doesn't line up precisely with the corresponding vertebrae, especially caudal to the thoracic spine. (emcrit.org)

The pial surface and superficial regions of the spinal cord are drained by radial veins and the coronal venous plexus. (medscape.com)
Whereas arterial occlusion in the spinal region quickly becomes symptomatic by neurological deficits, venous outflow obstruction may be clinically unnoticed for much longer and usually manifests as a slowly progressive neurological deficit. (fortunejournals.com)
The pathogenesis of sDAVFs is yet to be fully elucidated, conversely to their intracranial counterparts, in which dural venous thrombosis and neoangiogenesis contribute to the abnormal recanalization of the primitive direct connections between the arteries and veins around the major dural venous sinuses. (neurosurgicalatlas.com)
There are four recognized pathophysiologic mechanisms for the presentation of spinal cord vascular anomalies: 1) venous hypertension, 2) vascular steal syndrome, 3) subarachnoid hemorrhage, and 4) intraparenchymal hemorrhage (hematomyelia). (neurosurgicalatlas.com)
Focal or global venous hypertension is the most important mechanism for symptomatic presentation of dorsal spinal dAVFs. (neurosurgicalatlas.com)
The dural fistula becomes symptomatic as a result of spinal venous congestion, and not because the fistula directly involves a spinal cord artery. (neuroangio.org)

The dentate ligament is a long flange of whitish, mostly pial tissue that runs along both lateral margins of the spinal cord between the dorsal and ventral rootlets (see Fig 6-2 ). (neupsykey.com)
As the ventral and dorsal roots (on each side) at each segmental level converge to become a spinal nerve, they are enclosed in sleeves of arachnoidal and dural tissue (see Fig 6-2 ). (neupsykey.com)

Acute spinal cord ischemia syndrome (ASCIS) is predictably due primarily to pathology in the anterior spinal artery, its feeders or its branches. (biomedcentral.com)
The classic presentation for anterior spinal artery ischemia or infarct is sensory deficits in the following pattern: distal to the lesion, pain and temperature are lost bilaterally (owing to the involvement of anterolateral spinothalamic tracts), but light touch, vibration and position sense are preserved (owing to sparing of dorsal columns). (biomedcentral.com)

Spinal Intradural Fistula (a.k.a. (neuroangio.org)
When a fistula develops between any artery supplying the spinal cord and a spinal cord vein, it is called an intradural (pial) fistula. (neuroangio.org)

3 This location is favored because the agents can be injected into the anterior epidural space, i.e. the inflammatory site between the back of the herniated intervertebral disc and the anterior nerve root dural sleeve and the risk of decreasing dura mater puncture, as the injection needle goes through the border of the lateral upper intervertebral foramen.
