Extracranial-intracranial arterial bypass procedures provide important augmentation of collateral circulation to cortical areas rendered potentially ischemic by therapeutic occlusion of major branches of the circle of Willis. Although the case studies reported to date in general reflect positively on this use of the bypass procedure, this report of a patient who failed to tolerate acute middle cerebral artery occlusion despite the presence of a patent superficial temporal-middle cerebral artery branch anastomosis points up several of the practical and theoretical limitations of this therapeutic approach. Certain modifications of the timing of the bypass procedure, the selection of donor and recipient arteries, and the mechanics of intracranial arterial occlusion may allow a wider application of extracranial-intracranial arterial bypass in this therapeutic setting.
颅外-颅内动脉搭桥手术能显著增强侧支循环，为因治疗性闭塞 Willis 环主要分支而可能出现缺血的皮质区域供血。尽管迄今为止报道的病例研究总体上对搭桥手术的这种应用持肯定态度，但本报告中的一名患者，尽管存在颞浅动脉-大脑中动脉分支吻合通畅的情况，却仍无法耐受急性大脑中动脉闭塞，这凸显了这种治疗方法在实际应用和理论方面的一些局限性。对搭桥手术时机、供体和受体动脉的选择以及颅内动脉闭塞机制进行某些调整，可能会使颅外-颅内动脉搭桥手术在这种治疗场景中得到更广泛的应用。
