The investigators' goal is to compare the efficacy of three different management strategies (sacral neuromodulation, botulinum toxin, M receptor antagonist) in treating consistent OAB in patients with SVMs after surgery.

Spinal Vascular malformations (SVMs) are complex neurosurgical lesions and account for 3%-4% of all intradural spinal cord mass lesions, which can influence the function of bladder. The investigators' goal is to compare the efficacy of three different management strategies (sacral neuromodulation, botulinum toxin, M receptor antagonist) in treating consistent OAB (Overactive Bladder) in patients with SVMs after surgery.

Inclusion Criteria:

• •Patient diagnosed with spinal vascular diseases including Intradural arteriovenous malformation,Intradural arteriovenous fistula,Dural arteriovenous fistula,Extradural arteriovenous malformation,Paravertebral arteriovenous malformation,Paravertebral arteriovenous fistula,cobbs' syndrome,and other spinal arteriovenous metameric syndromes involve the spinal cord.

  • patient not received surgical or interventional treatment before
  • patient with normal cardiac, renal and hepatic function
  • patient capable of understanding the content of the patient information / Informed Consent Form
  • patient willing and able to participate in the registry
  • patients have consistent OAB after surgery

Exclusion Criteria:

• •patient received surgical treatment or interventional treatment before

  • patient is pregnant
  • patient allergic to iodine
  • patient unable to complete follow-up
  • patient with cerebral lesions
  • patient with other spinal lesions
  • patient with cardiac, renal or hepatic dysfunction
