Abstract：A 45-year-old male patient was admitted due to a 10-day history of paroxysmal chest pain,which worsened approximately 3 hours before presentation.The patient had a 7-year history of hypertension without regular treatment.Initial electrocardiogram indicated an acute ST-segment elevation myocardial infarction(STEMI)involving the inferior and posterior walls.Coronary angiography revealed complete occlusion of the left circumflex artery(LCX),and percutaneous coronary intervention(PCI)was performed with successful stent placement.Approximately 10 hours post-PCI,the patient suddenly developed drowsiness,right-sided hemiparesis and aphasia,indicating a possible acute ischemic stroke.Brain imaging confirmed occlusion of the left internal carotid artery and middle cerebral artery.Given the recent coronary intervention and contraindications to thrombolysis,emergency mechanical thrombectomy was performed,achieving successful recanalization.Postoperatively,the patient showed significant neurological recovery with improved right-sided muscle strength.This case underscores the importance of vigilance for cerebrovascular complications following coronary stenting,and emphasizes the critical role of multidisciplinary collaboration and timely intervention in improving patient outcomes.
