Spinal angiography

Spinal angiography is a method that uses water-soluble iodine and other contrast agents to inject into the subarachnoid space, and then performs X-rays or CT in time to show the lesions. The needle is usually inserted in the lumbar 3-4 or lumbar 4-5 space, and the contrast medium is slowly and continuously injected after the cerebrospinal fluid flows out. Applicable to lumbar spinal canal occupying lesions, disc herniation, spinal canal stenosis, spinal canal deformity, spinal degenerative lesions, etc. Special attention should be paid to those who are allergic to iodine, infection at the puncture site, and acute bleeding in the spinal canal.
