Endovascular Recanalization in Acute Ischemic Stroke Using the Solitaire FR Revascularization Device with Adjunctive...

Area of Science:

• Neurology
• Interventional Neuroradiology
• Medical Imaging

Background:

• Acute ischemic stroke treatment relies on timely reperfusion.
• Mechanical thrombectomy is a key intervention for large vessel occlusions.
• Challenges exist in visualizing device placement during thrombectomy, especially with poor initial angiography.

Purpose of the Study:

• To evaluate the utility of C-arm CT in conjunction with the Solitaire FR Revascularization Device for acute ischemic stroke.
• To assess the impact of C-arm CT on device deployment and visualization during mechanical thrombectomy.
• To analyze clinical outcomes including reperfusion, neurological deficit, and survival.

Main Methods:

• A single-center clinical report examining the use of the Solitaire FR Revascularization Device.
• Adjunctive C-arm CT was utilized during device deployment for enhanced visualization.
• Outcome measures included reperfusion extent, NIHSS scores, TICI scores, hemorrhage, and survival.

Main Results:

• Successful arterial recanalization was achieved in 15/18 cases (83.3%).
• All patients with initial recanalization achieved TICI scores of 2b/3.
• The average NIHSS score improved from 19 to 11, with a 72% survival rate.

Conclusions:

• C-arm CT provides valuable information on device placement and expansion during mechanical thrombectomy for acute ischemic stroke.
• This adjunctive imaging technique may improve outcomes in cases with poor initial angiographic visualization.
• The Solitaire FR device, with C-arm CT guidance, demonstrates efficacy in achieving reperfusion and improving patient survival.
