Insights
Intracranial angioplasty with coronary stents shows promise for stenosis treatment. However, a case of basilar artery stenosis demonstrated rapid re-stenosis and vessel rupture during stent-assisted angioplasty, highlighting potential complications.
Area of Science:
- Neurology
- Interventional Cardiology
- Vascular Surgery
Background:
- Intracranial artery stenosis poses a significant risk for stroke.
- Stent-assisted angioplasty is increasingly used for intracranial stenosis.
- Complications and long-term outcomes require further investigation.
Purpose of the Study:
- To report a rare case of basilar artery stenosis.
- To investigate the complications of stent-assisted angioplasty in this context.
- To analyze pathological findings following a procedure failure.
Main Methods:
- A case of basilar artery stenosis was treated with balloon angioplasty.
- The patient experienced rapid re-stenosis and underwent stent-assisted angioplasty.
- Autopsy was performed to examine the vessel pathology.
Main Results:
- Simple balloon angioplasty led to rapid re-stenosis.
- Stent-assisted angioplasty resulted in vessel rupture.
- Autopsy revealed vessel wall disruption and elastic lamina defects at the stent site.
Conclusions:
- While stent-assisted angioplasty is a viable option for intracranial stenosis, this case highlights potential severe complications.
- Rapid re-stenosis and vessel rupture can occur, necessitating careful patient selection and procedural monitoring.
- Pathological findings underscore the importance of understanding vessel wall response to stenting in the intracranial circulation.
Summary:
Intracranial artery angioplasty utilizing coronary stent is now widely tried as an effective alternative for treating intracranial artery stenosis, and several successful result of stent-assisted angioplasty for intracranial artery were reported. Authors experienced a case of the basilar artery stenosis, in which re-stenosis progressed rapidly after simple balloon angioplasty and resulted in vessel rupture during stent-assisted angioplasty. Pathological result achieved by autopsy showed vessel wall disruption at the stent and multiple interruptions and defect of elastic laminar.
