Summary
Rescuing detached Solitaire devices during mechanical thrombectomy for ischemic stroke is feasible and effective. Different stent retrievers demonstrated comparable success rates and times without complications.
Area of Science:
- Endovascular therapy
- Neurointerventional radiology
- Stroke treatment
Background:
- Mechanical thrombectomy with Solitaire devices is standard for large vessel occlusion ischemic stroke.
- Inadvertent detachment of Solitaire devices is a feared complication with poor outcomes.
Purpose of the Study:
- To assess the feasibility and effectiveness of rescuing detached Solitaire devices.
- To evaluate different stent retrievers for Solitaire device retrieval in a porcine model.
Main Methods:
- Solitaire FR devices were deployed in the porcine axillary artery.
- Three different stent retrievers (Trevo ProVue, EmboTrap II, 3D) were used for rescue maneuvers.
- Rescue rates, time, and complications were assessed for 24 rescue attempts.
Main Results:
- 100% success rate for stentectomy (retrieval) of detached Solitaire devices.
- Comparable rescue times across all tested stent retrievers.
- No complications such as migration, vasospasm, or dissection were observed.
Conclusions:
- Stentectomy using various stent retrievers is a feasible and effective method for retrieving detached Solitaire devices.
- Trevo ProVue, EmboTrap II, and 3D revascularization devices showed similar efficacy and safety profiles.
