Endovascular coil retrieval using a TrevoProVue stentriever

Area of Science:

• Neurosurgery
• Interventional Neuroradiology
• Vascular Surgery

Background:

• Cerebral aneurysms are treated with coil embolization, a procedure that carries risks.
• Complications such as coil migration can occur, necessitating retrieval.

Observation:

• During a cerebral aneurysm embolization, a framing coil detached prematurely.
• The dislodged coil migrated into the anterior cerebral artery and pericallosal artery.
• Standard retrieval devices (Microsnare) were unsuccessful.

Findings:

• A Trevo ProVue retrievable stent was utilized for foreign body retrieval.
• Successful retrieval of the dislodged coil was achieved using the stent.
• No adverse events were reported during the retrieval process.

Implications:

• This case demonstrates a novel application of retrievable stents for neurovascular foreign body removal.
• The Trevo ProVue stent offers a viable solution for complex coil retrieval scenarios.
• This technique may improve safety and outcomes in endovascular procedures.
