We present a case of tandem stenosis of the great vessels (cervical internal carotid artery [ICA] and brachiocephalic trunk ostium [BTO]) treated with stenting and balloon angioplasty of both lesions under flow arrest. A 70-yr-old woman with a history of hypertension, hyperlipidemia, coronary artery disease, and previous strokes presented with recurrent transient ischemic attacks of the left upper and lower extremities over the last 6 mo. She underwent right cervical endarterectomy (CEA) 16 yr prior. Neurological examination was unremarkable. Carotid Doppler ultrasonography revealed severely increased velocities of the right ICA. Cervical magnetic resonance angiography demonstrated 80% right ICA stenosis and 50% BTO stenosis. Digital subtraction cerebral angiography showed 80% right ICA stenosis and 70% BTO stenosis. The patient was not a candidate for standard carotid artery stenting because the BTO precluded endovascular access or for CEA because of the previous CEA; therefore, direct carotid access and flow reversal was an alternative. Under general anesthesia and systemic heparinization, the patient underwent right carotid artery surgical exposure. Under flow reversal using the Enroute System (Silk Road Medical, Sunnyvale, California), anterograde right ICA stenting angioplasty and retrograde BTO stenting and angioplasty were performed. Successful revascularization of the right ICA and BTO was obtained. No procedure-related complications occurred. The patient was discharged home 2 d postprocedure, neurologically intact. Direct carotid access with flow reversal is a safe and effective therapeutic alternative for patients with ICA (or common carotid artery) stenosis who cannot undergo CEA or when endovascular access from the aortic arch is not possible. Patient consent was obtained prior to performing the procedure. Institutional board approval is not required for the report of a single case.
我们报告一例大血管串联狭窄(颈内动脉[ICA]和头臂干开口[BTO])的病例,该病例在血流阻断下对两个病变均进行了支架置入和球囊血管成形术治疗。一名70岁女性,有高血压、高脂血症、冠状动脉疾病和既往中风病史,在过去6个月出现左上肢和下肢反复发作的短暂性脑缺血发作。她在16年前接受了右侧颈动脉内膜切除术(CEA)。神经系统检查无异常。颈动脉多普勒超声显示右侧ICA血流速度严重增加。颈部磁共振血管造影显示右侧ICA狭窄80%,BTO狭窄50%。数字减影脑血管造影显示右侧ICA狭窄80%,BTO狭窄70%。该患者不适合标准的颈动脉支架置入术,因为BTO妨碍了血管内通路,也不适合CEA,因为既往已行CEA;因此,直接颈动脉入路和血流逆转是一种替代方法。在全身麻醉和全身肝素化下,患者接受了右侧颈动脉手术暴露。在使用Enroute系统(Silk Road Medical,加利福尼亚州桑尼维尔)进行血流逆转的情况下,进行了右侧ICA顺行支架置入血管成形术和BTO逆行支架置入及血管成形术。成功实现了右侧ICA和BTO的血管再通。未发生与手术相关的并发症。患者术后2天出院,神经系统完好。对于不能接受CEA或无法从主动脉弓进行血管内通路的ICA(或颈总动脉)狭窄患者,直接颈动脉入路和血流逆转是一种安全有效的治疗选择。在进行该手术之前已获得患者同意。报告单个病例无需机构委员会批准。
