Project Description

This illustration depicts anastomoses of the vertebral artery (VA) that are relevant to VA sacrifice, which involves embolizing the VA with metallic microcoils across multiple cervical levels. In this case, the VA was sacrificed to reduce blood flow to an osteoblastoma. The anastomoses (red labels) from the suboccipital artery of Salmon, ascending cervical, and deep cervical arteries may recanalize the VA after sacrifice. The transverse and spinous processes, vertebral pedicles, and dura are sectioned to reveal the spatial relationships of the arterial supply (bold italic labels) of the spinal cord to the VA, which must be considered during VA sacrifice to avoid spinal cord damage.
