Mechanical thrombectomy for acute stroke with the alligator retrieval device

Area of Science:

• Neurology
• Interventional Neuroradiology
• Vascular Surgery

Background:

• Acute ischemic stroke requires rapid recanalization for improved patient outcomes.
• Endovascular devices are crucial for safe and effective thrombus removal.
• The Alligator retrieval device, initially for foreign body retrieval, is explored for its potential in stroke treatment.

Purpose of the Study:

• To evaluate the efficacy and safety of the Alligator retrieval device for thrombus removal in acute ischemic stroke.
• To assess the recanalization rates and patient outcomes following treatment with the Alligator device.

Main Methods:

• A retrospective case series of seven patients with acute ischemic stroke treated with the Alligator retrieval device.
• Intra-arterial therapy was administered using the Alligator device for thrombus extraction.

Main Results:

• Successful thrombus retrieval was achieved in 5 out of 7 patients.
• Good to excellent recanalization was observed in the majority of successful retrievals.
• Complete or near-complete recanalization occurred in 5 out of 7 patients.
• Three patients had a good outcome at 3 months, while three patients died within 30 days.

Conclusions:

• The Alligator retrieval device demonstrated success in thrombus removal for acute ischemic stroke patients.
• The device appears more effective in proximal occlusions within straight arterial segments.
• The Alligator retrieval device may be a valuable tool for intra-arterial stroke management in carefully selected cases.
