Using QDSA technology to assess cerebrovascular diseases

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to create a prospective cohort of patients with cerebrovascular diseases, utilizing the Quantitative Digital Subtraction Angiography (QDSA) platform to analyze hemodynamic parameters. By integrating DSA features, clinical data, and follow-up information, the study seeks to validate the clinical utility of QDSA in preoperative evaluations and surgical planning. The research will track patient outcomes over time, focusing on the natural history of the disease, risk factors, and treatment efficacy, ultimately aiming to enhance clinical decision-making in cerebrovascular conditions.
