Spinal arteriovenous malformation (AVM) is an abnormal tangle of blood vessels in the spinal cord. It can cause a range of symptoms, including back pain, weakness, numbness, and paralysis.
The treatment for spinal AVM depends on several factors, including the size and location of the malformation, as well as the patient’s symptoms and overall health. Decision of treatment is made after accessing risk-benefit ratio.
One treatment option for spinal AVM is embolization, which involves injecting a substance into the abnormal blood vessels to block blood flow and reduce the risk of bleeding. This may be done prior to surgery to reduce the risk of bleeding during the procedure, or as a standalone treatment for patients who are not candidates for surgery.
Surgery may also be an option for spinal AVM, particularly if the malformation is located in a surgically accessible area. During the procedure, the surgeon will remove the abnormal blood vessels to prevent bleeding and improve symptoms.
Radiation therapy may also be used to treat spinal AVM, although it is typically reserved for patients who are not candidates for embolization or surgery.
The specific treatment plan for spinal AVM will vary depending on the individual case. Your Interventional Radiologist will work with you to develop a treatment plan that is tailored to your specific needs and circumstances.
