The incidence of tandem occlusion of the internal carotid artery accounts for about 20% of patients with large vessel occlusion of the anterior circulation in acute ischemic stroke. The low rate of recanalization by intravenous thrombolysis in AIS due to internal carotid artery tandem occlusion, the poor establishment of collateral circulation within a short time, and the complex pathogenesis often suggest a poor prognosis for patients. Mechanical thrombectomy (MT) is beneficial for the opening of intracranial large vessel occlusion with internal carotid artery tandem occlusion, there are many problems regarding the emergency management of carotid artery occlusion or stenosis after mechanical thrombectomy, and there are currently no standardized treatment recommendations;The sequential approach to the management of carotid tandem occlusion, the timing of carotid stenting, and the use of antiplatelet agents remain controversial. The current state of research on carotid tandem occlusion is analyzed in the literature to promote clinical understanding of endovascular treatment for patients with acute ischemic stroke due to carotid tandem occlusion.展开更多

We here report a case of a tandem embolism, and the anatomy of the aortic arch was complex.Direct carotid artery incision and thrombectomy can not only prevent the escape of the carotid embolus but also save time during establishment of the thrombectomy access.CASE SUMMARY The patient was a 70-year-old man. He was admitted to hospital due to sudden inability to speak and inability to move his right limb for 3 h. Imaging confirmed a diagnosis of a tandem embolism in the left carotid artery with left M1 occlusion.Carotid artery incision thrombectomy combined with stent thrombectomy was performed. The operation was successful, and 24 h later the patient was conscious and mentally competent but had motor aphasia. His bilateral limb muscle strength level was 5, and his neurologic severity scores score was 2.CONCLUSION Carotid artery incision thrombectomy combined with stenting for carotid artery plus cerebral artery tandem embolization is clinically feasible. For patients with a complicated aortic arch and an extremely tortuous carotid artery, carotid artery incision can be chosen to establish the interventional path.展开更多
