[Internal carotid artery pseudoaneurysm and stenosis: treatment with stents and coils]

Area of Science:

• Vascular Surgery
• Interventional Neurology
• Endovascular Therapy

Background:

• Cerebrovascular diseases, including internal carotid artery (ICA) stenosis and pseudoaneurysms, pose significant risks.
• Post-dissection pseudoaneurysms of the ICA present complex management challenges.
• Endovascular approaches are increasingly utilized for cerebrovascular interventions.

Observation:

• A 45-year-old male presented with left hemiparesis.
• Angiography revealed right ICA occlusion, left ICA stenosis, and a pseudoaneurysm.
• The patient underwent endovascular treatment for the left ICA lesion.

Findings:

• An uncovered metallic stent was successfully deployed via a femoral approach.
• Coil embolization was performed through the implanted uncovered stent.
• The pseudoaneurysm was effectively excluded, and the stenosis was addressed.

Implications:

• Percutaneous implantation of an uncovered carotid stent followed by through-stent embolization is a viable endovascular strategy.
• This technique appears safe and effective for managing complex ICA stenosis with pseudoaneurysm.
• The method demonstrated no risk of coil migration, suggesting a favorable safety profile.
