上肢深静脉回流障碍暨上腔静脉综合征的超声诊断

目的 探索上肢深静脉回流受阻暨上腔静脉综合征（SVCS）患者的病因、病理改变、在超声和临床上的表现。方法 对5年来该病变10例患者作了回顾性的分析和总结。结果 10例患者中7例为SVCS，其中4例由右上肺恶性肿瘤引起，3例由右上、中纵隔恶性肿瘤引起。10例中2例因安装起搏器后导管置留于右锁骨下静脉而诱发血栓形成，1例为不明原因右腋静脉血栓形成。结论 超声声像图结合彩色和频谱多普勒能对病程演进和疗效评价提供有价值的信息。

Ultrasonic Diagnosis in Upper Extremity Deep Venous Flow Obstruction and Superior Vena Cava Syndrome

Objective To explore the pathogeny, pathology, ultrasonic and clinical expression of upper extremity deep venous flow obstruction and superior vena cava syndrome. Methods Retrospective analysis and summarize the disease changes of 10 cases in recent 5 years. Results 7 patients of 10 cases were superior vena cava syndrome, in which 4 cases caused by upper right lung malignant tumor, 3 cases caused by upper and media mediastinal malignant tumor. 2 patients of 10 cases were found thrombosis in right subclavian vein caused by duct of artificial pacemaker. The left 1 patient was no reason thrombosis in right axillary vein. Conclusion Ultrasonography combine with color and spectral Dopper image can evaluate the clinical development and therapeutic efficiency, which is a useful and effective non invasive examination.
