Abstract
OBJECTIVE: This study aimed to investigate the safety of endovascular thrombectomy in acute ischemic stroke with preexisting intracranial aneurysms. METHODS: Patients with acute ischemic stroke due to large-artery occlusion combined with intracranial aneurysms, who received endovascular treatment, were analyzed retrospectively, and the procedure-related data were recorded. RESULTS: Among the 124 patients who suffered acute large-artery occlusion and received endovascular recanalization therapy, intracranial aneurysms were found in seven patients (5.6%). All the seven patients achieved successful recanalization, except one patient who suffered subarachnoid hemorrhage due to the rupture of aneurysm during the procedure. CONCLUSIONS: The prevalence of preexisting cerebral aneurysms in patients with acute ischemic stroke is high, leading to a procedure-related rupture risk. Endovascular treatment devices must be used carefully in these patients, especially when the aneurysms are located within the area where the procedure is performed.
