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 requires parent artery occlusion, risking thrombosis.
• The Comaneci device is an innovative temporary bridging device designed for cerebral aneurysm coiling.

Observation:

• The Comaneci device was used in three patients undergoing cerebral aneurysm coiling.
• Two patients presented with acute ruptured posterior communicating aneurysms.
• One patient was electively treated for a carotico-ophthalmic aneurysm.

Findings:

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

Implications:

• The Comaneci device demonstrates potential for safe and effective cerebral aneurysm occlusion.
• It offers advantages over traditional balloon remodeling by avoiding parent artery occlusion.
• This technology may alleviate time pressure and reduce thrombosis risk in endovascular procedures.
