Endovascular interventional embolization in pregnancy-related acute large vessel occlusive stroke: an analysis of 3 cases and literature review / 中华神经医学杂志

ABSTRACT

Objective:To explore the feasibility and safety of endovascular interventional embolization in pregnancy-related acute large vessel occlusive stroke.Methods:Three patients with pregnancy-related acute large-vessel occlusive stroke accepted endovascular interventional embolization in Department of Neurology, Jining First People's Hospital from November 2017 to June 2021 were chosen; their clinical data and treatment efficacy were retrospectively analyzed.Results:Two patients were in early pregnancy and one was in puerperium; they were with acute anterior circulation large vessel occlusion, including one with occlusion of the M1 segment of the right middle cerebral artery, one with occlusion of the ophthalmic segment of the left internal carotid artery, and one with occlusion of the traffic segment of the left internal carotid artery; cardiogenic embolism was considered, and the risk factors for embolism included unclosed foramen ovale ( n=1), rheumatic heart disease ( n=1), and atrial fibrillation ( n=1); embolization was performed by catheter aspiration in one patient and stenting in two patients; all vessels were well re-canalized with modified thrombolysis in cerebral infarction (mTICI) 3; two patients had a good prognosis 90 d after embolization (mRS scores of 0 and 2) and one had a poor prognosis (mRS scores of 4); no surgical complications occurred. Conclusion:Endovascular interventional embolization after individualized evaluation may be a safe and effective approach for patients with pregnancy-related acute large vessel occlusive stroke.
