Intracranial mechanical recanalization and fibrinolysis using a single hyperglide balloon microcatheter. Technical...

Area of Science:

• Neurology
• Interventional Radiology
• Vascular Surgery

Background:

• Acute ischemic stroke due to middle cerebral artery occlusion is a leading cause of disability.
• Timely reperfusion is critical for improving outcomes in acute stroke.
• Endovascular therapy offers a direct approach to restoring blood flow.

Purpose of the Study:

• To evaluate the efficacy of a combined endovascular technique for acute middle cerebral artery blockages.
• To assess the feasibility of using a single microcatheter for both mechanical and chemical interventions.
• To determine the impact of this combined approach on procedure duration.

Main Methods:

• Mechanical recanalization using stent retrievers or aspiration catheters.
• Intra-arterial chemical fibrinolysis administration.
• Concurrent or sequential application of both techniques via a single microcatheter.
• Assessment of procedural success and time.

Main Results:

• Successful recanalization was achieved in a high percentage of cases.
• The combined approach using a single microcatheter was technically feasible.
• Significant reduction in overall procedure time compared to separate applications.

Conclusions:

• Endovascular treatment for acute middle cerebral artery blockages may necessitate both mechanical and chemical approaches.
• Utilizing a single microcatheter for combined mechanical recanalization and chemical fibrinolysis is an effective strategy.
• This integrated method streamlines the endovascular procedure, shortening treatment time.
