Summary
Intracranial stents combined with coil embolization offer benefits for treating complex brain aneurysms. While generally safe and effective, potential complications like neurological deterioration and aneurysm recurrence require careful consideration.
Area of Science:
- Neurosurgery
- Interventional Neuroradiology
- Vascular Neurology
Background:
- Intracranial aneurysms pose significant risks, necessitating advanced treatment modalities.
- Stent-assisted coil embolization is an emerging technique for complex intracranial aneurysms.
Observation:
- This study evaluated the outcomes of 10 patients with intracranial aneurysms treated with intracranial stents and coil embolization.
- Ten lesions, including broad-based and dissecting aneurysms in various locations, were treated.
- Angiographically satisfactory results were achieved in all 10 treated lesions.
Findings:
- Intracranial stent placement was technically successful in 10 out of 13 attempted cases.
- Two patients experienced permanent neurological deterioration post-procedure.
- Aneurysm recurrence occurred in two cases, managed successfully with repeat embolization or parent vessel occlusion.
Implications:
- Intracranial stents can be a valuable adjunct to coil embolization for complex aneurysms.
- The procedure offers mechanical, hemodynamic, and visual advantages.
- Careful patient selection and monitoring are crucial due to potential complications.
