Imaging, Intervention, and Workflow in Acute Ischemic Stroke: The Calgary Approach

Area of Science:

• Neurology
• Interventional Cardiology
• Vascular Surgery

Background:

• Acute ischemic stroke due to proximal anterior circulation artery occlusion is a leading cause of disability.
• Traditional treatments have limitations in restoring blood flow effectively.
• Recent clinical trials have investigated advanced treatment modalities.

Purpose of the Study:

• To review the results of recent clinical trials on endovascular treatment for acute ischemic stroke.
• To explore the heterogeneity in trial methodologies, including imaging, workflow, and device selection.
• To provide recommendations for optimizing patient selection and intervention strategies.

Main Methods:

• Focused review of five recent clinical trials.
• Analysis of eligibility criteria, imaging techniques, workflow, and endovascular devices used.
• Case study approach to illustrate the patient journey from evaluation to intervention.

Main Results:

• Endovascular treatment demonstrated significantly higher rates of favorable functional outcomes compared to standard care.
• A satisfactory safety profile was observed for endovascular treatment.
• Variations in trial eligibility criteria and methodologies were noted across studies.

Conclusions:

• Endovascular treatment is a highly effective option for acute ischemic stroke with proximal anterior circulation artery occlusion.
• Standardizing imaging and workflow protocols may further enhance treatment efficacy.
• Streamlined evaluation and intervention strategies are crucial for appropriate patient selection and timely treatment.
