A series of >300 studies (see reference 1) documented no or low rates of neurological and systemic complications with no neurological complication, <1% systemic complications and 1% rate of groin haematomas.
Left T8 supply to high flow spinal cord AVM, large nidus, superiorly draining veins reach to craniospinal junction (not shown), and inferiorly to the thoracolumbar region. Lateral view shows the arterial supply to enter the nidus anteriorly, AP shows it reaches the midline.
