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

Area of Science:

• Neurosurgery
• Interventional Radiology
• Vascular Surgery

Background:

• Endovascular management of giant aneurysms presents significant challenges.
• Standard techniques often fail due to complex anatomy and difficulty achieving distal access for catheter reduction.

Purpose of the Study:

• To describe a novel "Solitaire salvage technique" for endovascularly managing giant aneurysms.
• To evaluate the safety, efficacy, and efficiency of this technique in reducing a looped catheter within an aneurysm.

Main Methods:

• The Solitaire stent-retriever was utilized as an adjunctive device to achieve distal anchor points.
• Catheter reduction maneuvers were performed within the aneurysm sac.
• The technique was applied in three challenging clinical cases.

Main Results:

• Successful reduction of a looped catheter within the aneurysm was achieved in all three treated cases.
• The Solitaire salvage technique demonstrated effectiveness and safety.
• Compared to other methods, it was found to be more efficient.

Conclusions:

• The Solitaire salvage technique provides a viable and effective option for complex endovascular aneurysm treatment.
• While expensive, it is recommended when standard maneuvers are unsuccessful.
• This method enhances the safety and efficiency of managing challenging giant aneurysms.
