Abstract
Recent advances in neuroradiological techniques have increasingly improved the diagnosis rate for very small aneurysms, particularly with the widespread use of three‑dimensional cerebral angiography. However, the treatment of very small aneurysms remains a considerable challenge for neurosurgeons. Endovascular coiling has emerged as a potential treatment option for intracranial aneurysms. The aim of the present study was to evaluate the safety and efficacy of Solitaire AB stent‑assisted coiling embolization for the treatment of ruptured very small intracranial aneurysms. This retrospective study included nine consecutive patients with ruptured very small intracranial aneurysms (≤3 mm) that underwent Solitaire AB stent‑assisted coiling embolization. The aneurysms were located in the ophthalmic branch of the internal carotid artery (n=2), the posterior communicating branch of the internal carotid artery (n=4), the top of the basilar artery (n=1) and the middle cerebral artery (n=2). Solitaire AB stents were successfully implanted in all nine patients. Of the nice individuals, six patients exhibited complete occlusion at Raymond grade I and three patients exhibited occlusion at Raymond grade II. No aneurysm rupture was observed during the surgery. During the follow‑up period of 8‑13 months, no intracranial hemorrhage occurred. A total of seven patients underwent follow‑up digital subtraction angiography at 5‑10 months post‑intervention. No recurrence of the aneurysms and no stenosis or occlusion of the parent arteries was observed. Therefore, Solitaire AB stent‑assisted coil embolization was demonstrated to be a safe and effective treatment for ruptured very small intracranial aneurysms. The long‑term efficacy of this technique may be improved by increasing the packing density around the aneurysmal neck and improving the hemodynamics.
