The patient was admitted with unsteady gait and slurred speech for twelve hours, which had worsened over the preceding seven hours. Extracranial magnetic resonance angiography revealed no visualization of the bilateral vertebral arteries or the basilar artery. To further evaluate, digital subtraction angiography was performed, showing tandem lesions of the left vertebrobasilar artery. Emergency mechanical thrombectomy combined with stent implantation was performed. The patient was discharged in stable condition after treatment. Acute ischemic stroke caused by vertebrobasilar artery occlusion carries a high rate of morbidity and mortality. However, the incidence of vertebrobasilar tandem occlusion and the efficacy of endovascular treatment remain controversial. The underlying pathogenesis is most commonly related to atherosclerosis. Some patients initially present with vertigo, nausea, vomiting, or ataxia, while motor strength of the limbs may remain intact. With plaque rupture and recurrent embolization, patients may develop quadriplegia, impaired consciousness, or cardiopulmonary failure, which can be life-threatening. Here, we report a case of ischemic stroke caused by vertebrobasilar tandem lesions and provide a brief review of the literature. The aim is to improve clinicians’ understanding of this condition and to offer insight into the diagnosis and treatment of mild stroke resulting from vertebrobasilar occlusion.收起
