Endovascular treatment for cerebral aneurysms using stents

Area of Science:

• Neurosurgery
• Interventional Radiology
• Vascular Neurology

Background:

• Intracranial aneurysms pose significant risks, necessitating effective treatment strategies.
• Endovascular stent placement combined with coil embolization is a recognized therapeutic approach.

Purpose of the Study:

• To evaluate the outcomes of intracranial aneurysms treated with endovascular stent placement.
• To assess the safety and efficacy of this combined endovascular technique.

Main Methods:

• Retrospective analysis of 69 patients with 76 intracranial aneurysms treated over six years.
• Utilized stent placement with coil embolization for most aneurysms; stent alone for select cases.
• Outcome assessment via Glasgow Outcome Scale (GOS) and follow-up angiography.

Main Results:

• 74 aneurysms treated with 79 stents; 90.5% received combined therapy.
• Complete occlusion achieved in 43 aneurysms (63.2%) with progressive thrombosis in 19.4%.
• Favorable long-term outcome (GOS 4 or 5) in 92.8%; procedure-related mortality was 7.2%.

Conclusions:

• Endovascular stent placement is a valuable adjunct to coil embolization for complex intracranial aneurysms.
• The combined technique demonstrates a high rate of favorable long-term outcomes and acceptable safety profile.
• This approach offers a promising treatment option for challenging cerebrovascular lesions.
