外伤性颈动脉海绵窦瘘的眼上静脉彩色多普勒超声表现

Color Doppler ultrasonography of superior ophthalmic vein in traumatic carotid cavernous fistula

目的 探讨外伤性颈动脉海绵窦瘘（CCF）的超声表现和诊断价值.方法 2007年1月至2008年12月本院就诊的颅脑外伤患者10例,其中9例经数字减影血管造影确诊为CCF患者,对患者眶部彩色多普勒超声进行回顾性分析,总结其特点.结果 9例CCF患者均显示眼上静脉迂曲扩张、眼上静脉反向血流及动脉化血流频谱,扩张的眼上静脉管径在2.2～5.0 mm.结论 彩色多普勒超声诊断外伤性CCF经济、无创、准确,可作为首选的诊断方法.

Objective To investigate the presentation and diagnostic value of ultrasonography in traumatic carotid cavernous fistula （CCF）. Methods A total of 10 patients treated in our hospital between January 2007 and December 2008 were enrolled in this study. Among these patients, 9 were confirmed to have CCF by DSA. The characteristics of color Doppler ultrasonography in the orbit were retrospectively analyzed. Results All of the 9 cases showed dilated superior ophthalmic vein （SOV）, reverse flow in the SOV and arterialized flow spectrum. The diameter of dilated superior ophthalmic vein was 2.2 to 5.0 mm.Conclusion Color Doppler ultrasonography is cost-effective, non-invasive and accurate, and thus can be a first choice in diagnosis of CCF.
