Brief Summary

Cerebrovascular diseases pose a major global public health challenge, characterized by exceptionally high mortality and disability rates, with their pathogenesis closely linked to hemodynamic abnormalities. The quantitative digital subtraction angiography (QDSA) analysis platform, leveraging its advantages of vessel modeling-free operation, high computational efficiency, and DSA-equivalent sensitivity, has emerged as a novel hemodynamic assessment method with significant clinical potential. This study aims to establish a cerebrovascular disease cohort incorporating QDSA parameters to systematically validate the clinical value of this technology in preoperative evaluation and surgical planning, thereby providing evidence-based insights for optimizing diagnostic and therapeutic strategies.

Outcome Measures

Primary Outcomes (1)

  • Symptomatic stroke or death

    Stroke is defined as a clinically symptomatic event (any new focal neurological deficit, seizure, or new-onset headache) that is associated with imaging findings of hemorrhage or infarction. Hemorrhage is defined as fresh intracranial blood on head computed tomography (CT) or magnetic resonance imaging (MRI), or in the cerebrospinal fluid. Infarction is defined as a new ischemic lesion on cranial CT or MRI (diffusion-weighted, T2-weighted, or fluid-attenuated inversion recovery MRI).

    After treatment (max 10 years)

Secondary Outcomes (1)

  • Neurological status (modified Ranking Scale score)

    After treatment (max 10 years)

Study Arms (1)

Testing populations

Patients with cerebrovascular disease can be evaluated for quantitative hemodynamic characteristics using QDSA.

Device: QDSA (Quantitative Digital Subtraction Angiography)

Interventions

QDSA is a quantitative analysis technology based on DSA, used to assess hemodynamic characteristics and provide critical data support for the diagnosis and treatment of cerebrovascular diseases.

Study Population

Patients with cerebrovascular disease can be evaluated for quantitative hemodynamic characteristics using QDSA.

You may qualify if:

  • Cerebrovascular diseases diagnosed and assessed by DSA for related risks and treatment options.
  • The DSA acquisition protocol complies with the standard procedure.
  • DSA images must include complete anteroposterior and lateral views.
  • Raw data must be available in DICOM format.
  • Image quality and pixel resolution must support data analysis.
  • Patients must undergo regular follow-ups.

You may not qualify if:

  • Cerebrovascular diseases not diagnosed or risk-assessed using DSA.
  • Patients with DSA image quality insufficient for image analysis and processing.
  • Severe organ diseases with an expected survival period of less than 2 years.
  • Inability to cooperate with treatment and follow-up.
  • Participation in other clinical trials within the past 6 months.
  • Other conditions deemed by the investigator as unsuitable for participation in this trial.
