    Abstract:
    Intracranial kissing aneurysms, arising either from the same artery or from 2 adjacent arteries at similar locations, are rare.1,2 The internal carotid artery is most frequently involved; kissing aneurysms rarely affect the distal anterior cerebral artery (DACA). By dint of the close proximity of the aneurysm fundus, these aneurysms can pose unique operative challenges.3,4 A highly fragile aneurysm dome with a high intraoperative rupture rate is a unique management challenge in DACA aneurysms.5 The stakes are higher when there is an aneurysm rupture in the setting of kissing DACA aneurysms requiring an anterior interhemispheric approach. The negotiation of a tight interhemispheric fissure in between the bridging veins and prevention of a premature aneurysm rupture at a narrow space become vital in these situations. Video 1 highlights the surgical steps of clipping bilateral kissing DACA aneurysms in a 60-year-old woman. This surgical video highlights the microneurosurgical nuances of opening a tense interhemispheric fissure and maneuvers for prevention of a premature aneurysm rupture. These nuances are quintessential in the successful surgical clipping of kissing DACA aneurysms. The patient in Video 1 presented with an acute subarachnoid hemorrhage with severe headache of sudden onset and nuchal rigidity (World Federation of Neurological Surgeons grade II). Both aneurysms were located at the A3-A4 junction and successfully clipped through a right-sided anterior interhemispheric approach. She made a satisfactory postoperative recovery (modified Rankin Scale score of 1 at 6-week follow-up and 0 at 6-month follow-up) with an excellent angiographic outcome.
