摘要

59 岁的男性患者在过去 20 天内曾四次出现右眼一过性、无痛性视力下降,但都自行缓解。三年前,患者被诊断为口咽鳞癌,接受了六个周期的化疗和放疗。核磁共振脑血管造影显示,右颈内动脉弥漫性长段管壁增厚,管腔狭窄,无急性梗死或出血;后经四血管DSA证实。他接受了右颈内动脉血管成形术,术中使用了切割球囊和远端保护装置,随后进行了支架植入术。随访期间,患者恢复良好,没有再发作。因此,晕厥可能是颈动脉狭窄的一种表现,尤其是在放疗后,这类患者可以通过颈动脉血管成形术和支架植入术进行治疗。

Amaurosis Fugax Due to Radiationinduced Carotid Stenosis Treated by Carotid Artery Stenting
59-year-old male had four episodes of transient, painless vision loss in right eye in the last 20 days which had resolved spontaneously. Three years ago, patient had been diagnosed with oropharyngeal squamous cell carcinoma, which had been treated with six cycles of chemotherapy and radiotherapy. MRI brain angiogram showed diffuse long segment wall thickening of Right Internal Carotid Artery with luminal narrowing with no acute infarct or haemorrhage; which was later confirmed by four vessel DSA. He was treated with Right Carotid Artery angioplasty with a cutting balloon while using a distal protection device, followed up by stenting. The patient recovered well on follow-up and there were no further episodes. Thus, amaurosis fugax may be a presentation of carotid artery stenosis, especially after radiotherapy and such patients can be treated by carotid angioplasty and stenting.
