The most common indications for a DSA are:
- investigating a suspected cerebral or spinal vascular disease (e.g., aneurysms, vascular malformations, fistulas, tumors, etc.)
- preoperative planning
- postoperative check to evaluate the surgical result
DSA is often not the first step when investigating vascular diseases, but it is nonetheless an essential one. Often, the method is indispensable for reliably detecting or excluding a diagnosis.
At the USZ, we perform angiography mostly on an outpatient basis and under local anesthesia.
