Mechanical thrombectomy is a safe and effective treatment in patients with acute ischemic stroke caused by large vessel occlusions. However, in rare cases, the procedure may be challenging due to the composition of the embolus. We describe a case of a mechanical thrombectomy with the Embolus Retriever with Interlinked Cage (ERIC) device in a patient with an acute ischemic stroke due to calcified cerebral emboli in the middle cerebral artery. The procedure was done after a failed recanalization attempt with manual aspiration thrombectomy. An 82-year-old woman presented to the emergency department with a sudden onset of right-sided weakness. A computed tomographic angiography showed left middle cerebral (M1 branch) calcified emboli. After the administration of an intravenous thrombolytic agent, the patient was transferred to the angiographic suite for a mechanical thrombectomy. After failure to recanalize the vessel with manual aspiration thrombectomy, successful recanalization was achieved via mechanical thrombectomy using the ERIC device. Mechanical thrombectomy with an ERIC device can be a useful option in cases of acute ischemic stroke caused by calcified cerebral emboli.
机械取栓术对于由大血管闭塞引起的急性缺血性卒中患者而言是一种安全有效的治疗方法。然而，在罕见情况下，由于栓子的成分，该手术可能具有挑战性。我们描述了一例使用带有互连笼的栓子回收器（ERIC）装置对一名因大脑中动脉钙化脑栓子导致急性缺血性卒中的患者进行机械取栓的病例。该手术是在手动抽吸取栓术再通尝试失败后进行的。一名82岁女性因突发右侧肢体无力就诊于急诊科。计算机断层血管造影显示左侧大脑中动脉（M1分支）钙化栓子。在静脉注射溶栓药物后，患者被转至血管造影室进行机械取栓。在手动抽吸取栓术未能使血管再通后，通过使用ERIC装置进行机械取栓成功实现了再通。对于由钙化脑栓子引起的急性缺血性卒中病例，使用ERIC装置进行机械取栓可能是一种有用的选择。
