?Kissing? bilateral large carotid-ophthalmic aneurysms

Abstract

A case of unruptured bilateral large carotid-ophthalmic aneurysms, which appear to be adjoining and "kissing" each other when visualized by three-dimensional computed tomographic angiography (3-D CTA), is reported. Although bilateral carotid-ophthalmic aneurysms are not rare, bilateral large ones are quite rare, and direct imaging of "kissing aneurysms" of this portion has not been reported. Since 3-D CTA is becoming a useful tool for the diagnosis of cerebral aneurysms, we propose that these and similar bilateral large carotid-ophthalmic aneurysms are good candidates for the term "kissing aneurysms".

Bilateral Ophthalmic Segment "Kissing" Aneurysms Presenting With Subarachnoid Hemorrhage. Case Report.

“…Eight studies have described kissing aneurysms. 1,[5][6][7][8][11][12][13] The ipsilateral internal carotid artery is the most common origin of kissing aneurysms. The detailed clinical features of kissing aneurysms have recently been reviewed elsewhere.…”

“…2,3,13) However, bilateral ophthalmic segment aneurysms touching each other (kissing aneurysms) are extremely rare, with only one previous case of unruptured, large bilateral ophthalmic segment``kissing'' aneurysms. 1) Here, we report a case of bilateral ophthalmic segment``kissing'' aneurysms manifesting as subarachnoid hemorrhage. The closely situated, bilateral aneurysms necessitated a modified surgical strategy and had to be clipped concurrently, because it was not possible to determine which aneurysm had bled.…”

Endovascular Treatment of "Kissing Aneurysms" at the Anterior Communicating Artery

“…Kissing aneurysms can be defined as two anatomically adjacent aneurysms of different origin arteries, with the walls partially, pressed together 1,2,6,8,9,11) . In the circle of Willis, these aneurysms are quite rare and 0.2% incidence was reported by Yasargil 12) .…”

“…In the circle of Willis, these aneurysms are quite rare and 0.2% incidence was reported by Yasargil 12) . These kissing aneurysms have been treated either with separate neck clipping 1,2,6,9,11) , or endovascular treatment 3,7,8,10) . We report a case of subarachnoid hemorrhage (SAH) due to kissing aneurysms of AcomA that were treated by endovascular coil embolization successfully.…”

Kissing Aneurysms at the Junction of the Internal Carotid Artery and the Ipsilateral Duplicate Anterior Choroidal Arteries-Case Report-

“…The incidence of kissing aneurysms is approximately 0.1-3% in large aneurysm series. 2,4,12) The internal carotid artery (ICA) is the most common site of kissing aneurysms, [2][3][4]12) followed by the bilateral carotid-ophthalmic arteries, 1) the anterior communicating artery (bilateral A 1 -A 2 junctions), 11) the bilateral distal anterior cerebral arteries, 5,9) and the fenestrated proximal basilar artery. 7) All 14 previously reported cases of kissing aneurysms of the ipsilateral ICA consisted of an aneurysm located at the junction of the ICA and the posterior communicating artery, and another at the junction of the ICA and the anterior choroidal artery.…”
