Placement of a Pipeline Embolization Device: 2-Dimensional Operative Video.

Area of Science:

• Endovascular neurosurgery
• Cerebrovascular disease management
• Medical device innovation

Background:

• Traditional treatments for large internal carotid artery (ICA) aneurysms, such as carotid sacrifice or clipping, had significant limitations.
• Endovascular coil embolization alone was often ineffective for aneurysms causing mass effect, leading to coil compaction and enlargement.

Purpose of the Study:

• To demonstrate the efficacy of flow diversion in treating complex internal carotid artery (ICA) aneurysms.
• To provide a step-by-step visual guide of the flow diversion procedure for a recurrent cavernous ICA aneurysm.

Main Methods:

• Flow diversion using a stent to redirect blood flow away from the aneurysm.
• Treatment of a large recurrent cavernous internal carotid artery (ICA) aneurysm in a 72-year-old male.

Main Results:

• Flow diversion effectively diverts flow from the aneurysm, promoting thrombosis and shrinkage.
• Addresses limitations of previous treatments by alleviating mass effect and preventing coil compaction.

Conclusions:

• Flow diversion represents a significant advancement in treating wide-neck, large, and giant internal carotid artery (ICA) aneurysms.
• It offers a superior alternative to historical treatments by promoting aneurysm occlusion and symptom resolution.
