Summary
Primary stenting offers a safe and effective alternative for treating severe basilar artery stenosis when medical therapy fails. This endovascular approach avoids preliminary balloon angioplasty, achieving excellent outcomes in refractory cases.
Area of Science:
- Neurology
- Interventional Cardiology
- Vascular Surgery
Background:
- Symptomatic high-grade basilar artery stenosis poses a significant stroke risk.
- Medical therapy is often insufficient for refractory cases.
- Endovascular interventions are considered for severe stenosis.
Observation:
- Two patients with symptomatic, medically refractory basilar artery stenosis underwent endovascular stenting.
- The stenting procedure was performed successfully without prior balloon angioplasty.
- No procedural or periprocedural complications were observed.
Findings:
- Excellent angiographic results were achieved post-stenting.
- Both patients remained asymptomatic and neurologically intact at follow-up (mean 6.5 months).
- Primary stenting demonstrated high efficacy and safety.
Implications:
- Primary stenting of the basilar artery is a viable alternative to balloon angioplasty.
- This technique is suitable for patients refractory to medical management.
- It offers a treatment option for patients with contraindications to anticoagulation.
