Initial experience of coiling cerebral aneurysms using the new Comaneci device

Area of Science:

• Neurosurgery
• Interventional Neuroradiology
• Medical Devices

Background:

• Cerebral aneurysms pose significant risks, often treated with endovascular coiling.
• Conventional balloon-assisted coiling can carry risks such as parent artery occlusion and thrombosis.
• A need exists for safer, effective adjuncts in aneurysm coiling procedures.

Observation:

• The Comaneci device was evaluated as a temporary bridging device for cerebral aneurysm coiling.
• Three patients underwent treatment using the Comaneci device for various aneurysm types.
• The device aims to provide benefits similar to balloon remodeling without parent artery occlusion risks.

Findings:

• Excellent occlusion was achieved in all three treated cerebral aneurysms.
• The Comaneci device maintained vessel patency throughout the procedures.
• One patient experienced a distal middle cerebral artery clot, managed with aspirin and resulting in minor neurological deficits.

Implications:

• The Comaneci device demonstrates potential for safe and effective cerebral aneurysm occlusion.
• It may offer advantages over traditional balloon-assisted coiling by mitigating risks of parent artery compromise.
• Further investigation is warranted to establish the long-term efficacy and safety of this innovative device.
