What percentage of patients experience major complications from cerebrovascular angiography?

Cerebrovascular angiography, while generally a safe procedure, does carry a risk of complications. Major complications, which can include neurological deficits, vascular injuries, and significant bleeding, occur in a small percentage of patients. The rate of major complications from cerebrovascular angiography is often cited around 1%. This statistic underscores that while the procedure is crucial for diagnosing and treating cerebrovascular diseases, it is important to weigh the benefits against the risks.

The other percentages represent lower rates, which do not align with the established understanding of complication rates associated with this specific procedure. Thus, 1% not only reflects a common consensus in the literature but also provides a reasonable estimate of the potential complications faced by patients undergoing cerebrovascular angiography.
