Solitaire salvage: a stent retriever-assisted catheter reduction technical report

Area of Science:

• Endovascular neurosurgery
• Cerebrovascular diseases
• Interventional neuroradiology

Background:

• Endovascular treatment of giant aneurysms presents significant challenges, particularly in achieving distal access for catheter reduction.
• Anatomical complexities often render standard techniques unsafe or infeasible for these complex lesions.

Observation:

• The use of adjunctive devices for catheter reduction is established, but the Solitaire stent-retriever offers potential advantages.
• A novel "Solitaire salvage technique" was developed to address difficulties in catheter reduction within giant aneurysms.

Findings:

• The described Solitaire salvage technique successfully enabled catheter reduction within a giant aneurysm in three patient cases.
• This method proved effective, safe, and more efficient compared to alternative approaches, particularly after standard techniques failed.

Implications:

• The Solitaire salvage technique provides a valuable alternative for complex endovascular aneurysm treatment.
• While costly, it represents a viable, efficient, and safe option for challenging giant aneurysm cases when other methods are unsuitable.
