Cerebral DSA is a minimally invasive angiography test that uses a contrast dye and high-speed X-ray imaging to produce detailed pictures of the arteries and veins in the brain. The “subtraction” technique removes bones and surrounding tissue from the images, leaving only clean, high-precision images of blood vessels.
Cerebral DSA provides clear, real-time visualization of brain arteries and veins for accurate diagnosis and treatment planning.
Cerebral DSA is considered the gold standard investigation for evaluating brain blood vessels and detecting abnormalities responsible for stroke, bleeding, or neurological symptoms.
- Brain aneurysms
- Arteriovenous malformations (AVMs)
- Arteriovenous fistulas (AVFs)
- Carotid or vertebral artery stenosis
- Vasculitis and cerebral venous thrombosis
- Ischemic stroke and tumor vascularity
Why Is Cerebral DSA Done?
Cerebral DSA is performed for accurate diagnosis, treatment planning, and guidance of advanced neurovascular procedures.
Cerebral DSA helps diagnose aneurysms, AVMs, AVFs, carotid or vertebral artery stenosis, vasculitis, cerebral venous thrombosis, ischemic stroke, and tumor vascularity.
It is performed before aneurysm coiling, AVM or AVF embolization, carotid stenting, and neurosurgical procedures.
Cerebral DSA guides mechanical thrombectomy for stroke and various embolization procedures with real-time imaging.
Under local anesthesia, a catheter is inserted via the femoral or radial artery, guided to brain-supplying vessels, contrast is injected, and high-speed X-ray images are captured in real time.
Patients with unexplained severe headaches, stroke or TIA symptoms, suspected aneurysm or AVM, carotid disease, abnormal CT/MRI angiography, or those planned for brain surgery or endovascular treatment.
