Summary
Intracranial angioplasty is a feasible treatment for severe stenosis, but carries risks. Complications include vasospasm and stroke, requiring careful patient selection and management.
Area of Science:
- Neurology
- Interventional Neuroradiology
Background:
- Severe intracranial stenosis poses a significant risk of stroke.
- Percutaneous transluminal angioplasty (PTA) is an endovascular technique used to open narrowed cerebral arteries.
Purpose of the Study:
- To review the experience and complications of intracranial angioplasty (PTA).
Main Methods:
- A review of 10 patients who underwent intracranial PTA between 1993 and 1996 for stenosis of 75% or greater.
- Targeted vessels included internal carotid, middle cerebral, basilar, and vertebral arteries.
Main Results:
- Technical success was achieved in 80% of cases (8 out of 10 patients).
- Complications included vasospasm (5 patients), leading to stroke in 2 patients.
- Arterial dissection and compromise of perforating vessels were also associated with stroke in 2 patients.
Conclusions:
- Intracranial PTA is technically feasible for treating severe stenosis.
- Risks include vasospasm, arterial trauma, and compromise of perforating vessels, necessitating careful consideration.
