Abstract

Abstract An 86-year-old woman with initially asymptomatic severe right common carotid artery stenosis had frequent transient left hemiparesis 2 years after the initial diagnosis. Magnetic resonance angiography and three-dimensional computed tomography angiography demonstrated short-segment occlusion of the right carotid bifurcation with significant circumferential calcification, while magnetic resonance imaging demonstrated no ischemic lesions. No collateral blood flow through the anterior communicating artery and posterior communicating artery was observed. A bridging bypass from the distal common carotid artery to the proximal cervical internal carotid artery using a saphenous vein graft was made. There were no ischemic symptoms following the procedure. Bridging bypass using the short saphenous vein graft might be useful for short-segment common carotid artery occlusion.
短隐静脉搭桥治疗症状性颈总动脉闭塞1例
摘要一名86岁女性,最初无症状的严重右侧颈总动脉狭窄,在初次诊断后2年出现频繁的短暂性左侧偏瘫。磁共振血管造影和三维计算机断层血管造影显示右侧颈动脉分叉短段闭塞伴明显的周向钙化,而磁共振成像显示未见缺血性病变。前交通动脉和后交通动脉未见侧支血流。使用隐静脉移植物从颈总动脉远端到颈内动脉近端进行桥接搭桥。手术后无缺血性症状。短隐静脉移植物桥接旁路可能对短段颈总动脉闭塞有用。
