Digital Subtraction Angiography (DSA) – Spinal

What is Spinal DSA?

Digital Subtraction Angiography (DSA) – Spinal is a specialized, minimally invasive imaging technique used to visualize the blood vessels of the spine in great detail. By using contrast dye and advanced X-ray technology, DSA provides high-resolution images that help detect vascular abnormalities, such as spinal AVMs (arteriovenous malformations), fistulas, or tumors affecting spinal blood flow.

This procedure “subtracts” pre-contrast images from contrast-enhanced images, offering a clearer view of spinal vasculature without interference from surrounding bone or tissue.

When is Spinal DSA Recommended?

Spinal DSA is often advised when patients present with:

  • Unexplained chronic back pain with neurological deficits

  • Sudden onset of limb weakness or paralysis

  • Signs suggestive of spinal vascular malformations or tumors

  • Recurrent spinal hemorrhages

  • Suspicion of spinal dural AV fistula or AVMs

  • Spinal cord ischemia or infarction

It plays a crucial role in diagnosis when MRI/MRA findings are inconclusive or require vascular confirmation.

Treatment Role of Spinal DSA

Spinal DSA is both a diagnostic and pre-therapeutic tool. It allows:
  • Accurate localization and characterization of spinal vascular lesions
  • Planning for endovascular treatment or surgery
  • Guidance for embolization therapy in vascular malformations
  • Pre-surgical vascular road mapping
  • Assessment of post-treatment outcomes or complications
