Fenestrated clips for internal carotid artery aneurysms. Technical note.

Area of Science:

• Neurosurgery
• Vascular Surgery
• Medical Device Innovation

Background:

• Internal carotid artery (ICA) aneurysms often present unique anatomical challenges.
• Existing aneurysm clips may not be optimally designed for the posterolateral protrusion common in ICA aneurysms.

Purpose of the Study:

• To introduce a newly developed fenestrated aneurysm clip specifically engineered for internal carotid artery (ICA) aneurysms.
• To evaluate the initial safety and applicability of this novel clip in clinical settings.

Main Methods:

• Development of a fenestrated aneurysm clip with laterally deviating occluding blades.
• Application of the clip in a series of seven patients diagnosed with ICA aneurysms.

Main Results:

• The fenestrated clip was successfully applied in all seven patients.
• The application of the clip was deemed safe in the studied patient cohort.

Conclusions:

• The novel fenestrated aneurysm clip is a potentially safe and effective device for treating internal carotid artery (ICA) aneurysms.
• The clip's design addresses the specific anatomical characteristics of ICA aneurysms, facilitating safer application.
