Abstract

Purpose: We report the case of a 28-year-old man who developed Elschnig spots after stenting for an internal carotid artery dissection using optical coherence tomography angiography.

Methods: This was a case report.

Results: The patient developed a visual field defect in the left eye immediately after endovascular stenting for left internal carotid artery dissection. Fundus examination revealed white lesions and numerous mottled orange-red lesions in the posterior pole and midperiphery of the left eye. Indocyanine green angiography revealed mottled hypofluorescein areas in the early and late stages, coinciding with the orange-red lesions. Optical coherence tomography angiography showed flow void areas in the choriocapillaris layer, consistent with the orange-red lesions, which were diagnosed as Elschnig spots associated with choroidal circulatory failure. The spots disappeared approximately 2 months after surgery, and the flow void on optical coherence tomography angiography also disappeared.

Conclusion: We report a case of Elschnig spots associated with transient choroidal circulatory failure after stenting for internal carotid artery dissection. Optical coherence tomography angiography detected improved circulation at the level of the choriocapillaris with the disappearance of Elschnig spots.

一例颈内动脉夹层支架置入术后使用光学相干断层扫描血管造影术观察到的Elschnig斑点。

目的：我们报告一例28岁的男性患者，他在使用光学相干断层扫描血管造影术（OCTA）进行颈内动脉夹层支架植入术后出现Elschnig斑点。方法：病例报告。结果：患者在左颈内动脉夹层血管内支架置入术后立即出现左眼视野缺损。眼底检查显示，左眼后极和中周边有白色病变和大量斑点橙红色病变。吲哚青绿血管造影术显示早期和晚期有斑驳的低荧光素区域，与橙红色病变相吻合。OCTA显示脉络膜毛细血管层有流动空隙区，与橙红色病变一致，被诊断为与脉络膜循环衰竭相关的Elschnig斑点。术后约2个月，斑点消失，OCTA上的流动空隙也消失了。结论：我们报告了一例颈内动脉夹层支架置入术后并发短暂性脉络膜循环衰竭的Elschnig斑点。OCTA检测到绒毛膜毛细血管水平的循环改善，Elschnig斑点消失。
