Is cerebral angiography necessary?

Cerebral angiography, which uses digital silhouette angiography to show the entire circulation of cerebral vessels from arteries to veins, is a reliable means of diagnosing cerebrovascular diseases and provides sufficient imaging evidence for the treatment of other brain diseases. Therefore, if a professional neurologist recommends cerebral angiography, it should be considered without contraindications. However, angiography is an invasive examination after all, and complications are common, such as hematoma at the puncture site, vascular dissection, thrombosis, vascular perforation, vascular wall injury, etc.
