Fenestrated Angled Clip with Upward Curved Blade for Ophthalmic Segment Aneurysms: Technical Note

Abstract

A minor modification of Sugita's fenestrated angled aneurysm clip allows complete neck clipping, especially for the ophthalmic segment aneurysms (suprasellar and paraclinoid variants). The blade of this clip is curved upward to just fit the medial-to-lateral bend of the internal carotid artery (C3-C2 portion), where the aneurysm neck is located. Since it is not rare to be unable to clip the aneurysm neck properly with the existent style of clip due to the presence of surrounding structures and the bend of the parent artery (both anterior-to-posterior and medial-to-lateral), this simple modification by curving the blade of Sugita's fenestrated angled aneurysm clip might be particularly useful for the complete aneurysm neck clipping of the ophthalmic segment aneurysms.
