标准化A/B超诊断眼眶血管性病变的价值

目的：探讨标准化A／B超在诊断眼眶血管性病变中的价值。方法：对145例眼眶血管性病变患者行标准化A／B超检查。结果：在145例血管性病变中海绵状血管瘤79例，静脉血管瘤19例，淋巴管瘤15例，婴儿型血管瘤5例，静脉曲张12例，颈动脉海绵窦瘘15例（经数字减影血管造影证实）。标准化A／B超的阳性诊断率为98.6%，假阴性为1.4%。结论：标准化A／B超对眼眶血管性病变可作出较准确诊断。B超主要用于对病变形状、位置、病变与周围结构关系的显示，而A超优点在于对病变内部结构和组织学结构、声衰减的判断及定量测量。A／B超联合使用可获得最佳诊断效果。

Study of standardized A/B ultrasonography for diagnosis of orbital vascular lesions

Objective To study the application of standardized A/B ultrasonography for the orbital vascular lesions. Methods Standardized A/B ultrasonography was performed on orbital vascular lesions of 145 cases. Results The orbital vascular lesions included the cavernous hemangiomas in 79 cases, venous hemangiomas 19 cases, lymphangiomas 15 cases, infantile hemangiomas 5 cases, varix 12 cases and carotid-cavernous sinus fistula 15 cases. The positive rate of standardized A/B scans was 98.6 %, false negative 1.4 %.Conclusions Standardized A/B ultrasonography can make accurate diagnosis for orbital vascular lesions. B-mode ultrasonography mainly shows the shape, location and the relation to normal orbital structure, but A-mode ultrasonography is more accurate in internal reflectivity of lesions, and sound attenuation and quantitative. Combined B-mode and A-mode ultrasonography is more effective for diagnosis of orbital vascular lesions.
