Abstract

Two carotid ophthalmic artery aneurysms with incorporation of the artery into the neck were referred for endovascular assessment. Temporary balloon occlusion at the aneurysm neck was performed in an attempt to assess the adequacy of collateral flow to the retina. During inflation, the patients reported visual deterioration that resolved upon deflation, which indicates that collateral blood flow was insufficient. The patients were referred for surgical clipping to ensure preservation of the ophthalmic artery.

摘要

两名伴有颈内动脉眼动脉动脉瘤且动脉被纳入瘤颈的患者被转诊进行血管内评估。在动脉瘤颈部进行了临时球囊闭塞,试图评估视网膜侧支血流的充足性。在球囊充气过程中,患者报告视力恶化,放气后视力恢复,这表明侧支血流不足。患者被转诊进行手术夹闭以确保眼动脉的保留。
