Endovascular coil retrieval using a TrevoProVue stentriever

Area of Science:

• Neurosurgery
• Interventional Neuroradiology
• Vascular Neurology

Background:

• Cerebral aneurysms require endovascular treatment, often involving coil embolization.
• Complications such as coil detachment and migration can occur during these procedures.
• Retrieval of migrated coils presents a significant technical challenge.

Observation:

• During coil embolization of a cavernous internal carotid artery aneurysm, a framing coil detached and herniated into the anterior and pericallosal arteries.
• Standard retrieval devices, including Microsnare snares, were unsuccessful in removing the displaced coil.
• A Trevo ProVue retrievable stent was employed as a novel retrieval tool.

Findings:

• The Trevo ProVue stent successfully ensnared and retrieved the herniated coil.
• The retrieval procedure was completed without any adverse events or complications.
• This represents a successful application of a retrievable stent for foreign body removal in the cerebrovasculature.

Implications:

• This case demonstrates a new, effective technique for managing coil migration during aneurysm embolization.
• Retrievable stents offer a viable option for foreign body retrieval in challenging neurovascular scenarios.
• This approach may improve patient safety and procedural outcomes in interventional neuroradiology.
