Lumbar spinal angiography is one of the effective methods to diagnose lesions in and around the lumbar spinal canal and spinal cord, but is invasive, has certain complications, and carries certain risks. Also known as myelography, lumbar spinal angiography is an important examination method to diagnose intravertebral space-occupying lesions and spinal cord lesions by injecting a contrast agent (usually water-soluble iodine) into the vertebral canal through a lumbar puncture, and observing under fluoroscopic vision how the contrast agent fills and circulates in the canal. Spinal canalography itself is an invasive and traumatic operation, and therefore, has certain complications. A few people may experience headache, fever, vomiting, and aggravation of existing symptoms within a few days after a vertebral angiogram, with varying degrees of severity. Those with mild symptoms do not need to be treated, and most of them can be relieved naturally; for those with more severe symptoms, symptomatic treatment such as painkillers and hormone therapy can be given. As the spinal myelography needs to inject contrast agent into the spinal cord cavity, the contrast agent may cause anaphylaxis, infection, spinal cord arachnoid adhesion and other risks, and in severe cases, it may cause paralysis or death of the patient, so it is forbidden for people who are allergic to iodine, infection at the puncture site, acute bleeding in the spinal canal and other people when choosing the test. If you need to do lumbar spinal imaging test patients, it is recommended to go to a regular hospital, active cooperation to reduce the adverse effects of the test.
