Summary
Flexible metallic stents may induce spontaneous thrombosis in saccular intracranial aneurysms. This minimally invasive approach offers a potential alternative to traditional treatments for complex brain aneurysms.
Area of Science:
- Neurosurgery
- Interventional Neurology
- Vascular Medicine
Background:
- Surgical and endovascular treatments for broad-based intracranial aneurysms are complex.
- Flexible metallic stents facilitate coil placement for aneurysm treatment.
- Extracranial artery evidence suggests spontaneous aneurysm thrombosis post-stenting.
Observation:
- This case report details three patients with saccular intracranial aneurysms.
- Aneurysm thrombosis was observed solely after stent placement.
- No additional coil packing was performed in these cases.
Findings:
- Stent placement alone, without coil embolization, led to aneurysm thrombosis in all three patients.
- This suggests a potential mechanism for aneurysm occlusion mediated by stenting.
- Successful thrombosis was achieved in saccular intracranial aneurysms.
Implications:
- Flexible metallic stents may represent a standalone treatment for select intracranial aneurysms.
- This approach could offer a less invasive alternative to conventional methods.
- Further research is warranted to explore stent-induced thrombosis for aneurysm treatment.
