Intravascular treatment for cerebral aneurysms

Area of Science:

• Neurosurgery
• Interventional Radiology
• Vascular Neurology

Background:

• Aneurysms pose significant risks, necessitating effective treatment options.
• Endovascular techniques offer minimally invasive approaches for aneurysm management.

Purpose of the Study:

• To evaluate the efficacy of metallic coil embolization for intrasaccular and parent artery occlusions.
• To assess the outcomes, including occlusion rates, morbidity, and mortality, of this endovascular treatment.

Main Methods:

• Retrospective analysis of 142 aneurysm treatments.
• Procedures included selective intrasaccular occlusions and parent artery occlusions.
• Metallic coils were used for embolization.

Main Results:

• Intrasaccular occlusion was attempted in 109 cases, with 93 of 96 achieving total or subtotal occlusion.
• Parent artery occlusion was attempted in 33 cases (25 giant ICA aneurysms, others vertebral artery aneurysms), achieving occlusion in 30.
• Six ischemic symptoms were noted in the parent artery occlusion group.

Conclusions:

• Metallic coil embolization demonstrates a high occlusion rate for aneurysms.
• The endovascular approach shows low morbidity and mortality, proving its efficacy.
• This treatment is effective for various aneurysm types, including giant ICA and vertebral artery aneurysms.
