Summary
Coil migration during embolization is a critical complication. The Solitaire stent, typically used for stroke treatment, was successfully employed to retrieve a dislodged embolization coil from the internal carotid artery.
Area of Science:
- Endovascular neurosurgery
- Cerebrovascular intervention
- Medical device innovation
Background:
- Coil migration during embolization procedures presents an emergency requiring immediate intervention.
- Ruptured giant aneurysms, particularly in the ophthalmic segment of the internal carotid artery (ICA), pose significant treatment challenges.
Observation:
- A case of subarachnoid hemorrhage in a 71-year-old female due to a ruptured giant ophthalmic segment ICA aneurysm is presented.
- During endovascular embolization, a coil migrated distally within the internal carotid artery.
Findings:
- The dislodged coil was successfully retrieved using the self-expanding Solitaire AB stent.
- This demonstrates the Solitaire stent's utility beyond its primary indication for mechanical thrombectomy.
Implications:
- The Solitaire stent offers a viable and effective option for retrieving migrated coils during embolization.
- This case highlights the adaptability of neurointerventional devices for managing unexpected complications.
