Temporary Stent-Assisted Coil Embolization as a Treatment Option for Wide-Neck Aneurysms

Area of Science:

• Neurosurgery
• Interventional Radiology
• Vascular Neurology

Background:

• Simple coil embolization is often insufficient for wide-neck aneurysms.
• Stent-assisted coiling stabilizes coils but requires long-term antiplatelet therapy.
• Temporary stent-assisted coiling offers an alternative for wide-neck aneurysm treatment.

Purpose of the Study:

• To retrospectively analyze the effectiveness and safety of temporary stent-assisted coiling.
• To evaluate this technique in a larger patient cohort than previously reported.

Main Methods:

• Retrospective analysis of patients undergoing endovascular aneurysm treatment between 2010-2015.
• Inclusion of 33 patients treated with temporary stent-assisted coiling for incidental or acutely ruptured aneurysms.

Main Results:

• Sufficient aneurysm occlusion achieved in 97.1% of cases.
• Successful stent retrieval in 94% of procedures.
• Complications occurred in 14.7% of patients, with only one complication specific to the technique.

Conclusions:

• Temporary stent-assisted coiling is an effective treatment for wide-neck aneurysms.
• The safety profile is comparable to traditional stent-assisted coiling and balloon remodeling techniques.
