DSA angiography helps detect early vascular abnormalities and accurately identify damaged vascular locations. DSA angiography is currently considered the "gold standard" in diagnostic imaging techniques for vascular diseases.

DSA is a diagnostic imaging method that combines X-rays and digital processing. When taking a DSA, the patient must insert instruments into the groin, where bleeding or hematoma may occur. Therefore, during a DSA, the patient must lie still for 24 hours.
