Insights
Coronary stents effectively restored blood flow in chronically occluded intracranial vertebral arteries and external carotid artery stenosis. Intracranial artery stenting is viable for specific cases of chronic total occlusion or external compression.
Area of Science:
- Neurology
- Interventional Cardiology
- Vascular Surgery
Background:
- Intracranial artery stenting is infrequently reported.
- Stenosis in intracranial arteries can result from chronic total occlusion or external compression.
- Few studies have explored the use of coronary stents for intracranial applications.
Purpose of the Study:
- To evaluate the efficacy of coronary stents in treating intracranial arterial stenosis.
- To assess the feasibility of using coronary stents in chronically occluded intracranial vertebral arteries.
- To determine the indications and limitations of intracranial artery stenting.
Main Methods:
- Coronary stents were utilized in cases of chronically occluded intracranial vertebral artery.
- Stenting was performed for internal carotid artery stenosis caused by external force.
- Patient outcomes were assessed based on blood flow restoration.
Main Results:
- Successful restoration of good blood flow was achieved in treated patients.
- Coronary stents proved effective in managing complex intracranial arterial lesions.
- The study demonstrated the potential of stenting for specific types of intracranial stenosis.
Conclusions:
- Stenting is a viable option for intracranial arterial stenosis due to chronic total occlusion or external compression.
- Careful patient selection is crucial, requiring specific anatomical criteria for successful intracranial stenting.
- Further research is warranted to fully understand the long-term outcomes and challenges of intracranial stenting.
Summary:
There have been few reports of stenting in the intracranial arteries.We used coronary stents in the chronically occluded intracranial vertebral artery and stenosis of internal carotid artery by the external force, and good blood flow were resumed. Stenosis in the intracranial arteries is also a good indication for stent placement when it is due to chronic total occlusion or artery compression by external force. But stent placement in the intracranial arteries has some problems. Stent placement in the intracranial artery is indicated only when the site of stent placement has a diameter of 3 mm or more, is a relatively linear portion of the vertebrobasilar artery or the internal carotid artery proximal to the C3 segment, and does not branch off perforating arteries or is already completely occluded.
