Purpose: Kissing aneurysms (KAs) are caused by the rare incidence of two aneurysms with different cervixes mutually contacting each other, with craniotomy surgical clipping having been reported as difficult. The objective was to investigate the treatment outcome of single-stage coil embolization using an Enterprise stent for internal carotid artery KA.
Materials and Methods: The subjects consisted of three cases and six aneurysms (women: two cases, age: 42–70 years old, average: 55.7 years old) that underwent single-stage coil embolization using an Enterprise stent. Localization of the aneurysms was as follows: internal carotid artery-ophthalmic arterial bifurcation and internal carotid artery (C3): one case; internal carotid artery-posterior communicating arterial bifurcation and anterior choroidal arterial bifurcation: two cases; wherein, the maximum aneurysm diameter was 2.8–7.6 mm (average: 5.1 mm). The technical success rate, the presence of perioperative complications, the degree of embolus follow-up cerebral angiography after treatment (4–6 months, average: after 4.7 months), and more than 3 years follow-up contrast-enhanced magnetic resonance angiography (after 3.4–4.1 years, average: after 3.7 years) were assessed.
Results: Coil embolization was successful in all cases, with no observation of perioperative complications. Upon follow-up angiography, complete occlusion (CO) was observed in all three cases and six aneurysms.
Conclusion: The initial treatment outcome of single-stage coil embolization for carotid KA using an Enterprise stent was good.
