Superior vena cava syndrome (SVCS) groups all the signs secondary to the obstruction of superior vena cava drainage and the increase in the venous pressure in the territories upstream. There are two major causes of SVCS: malignant, dominated by bronchopulmonary cancer, and benign, often secondary to the presence of poorly positioned implantable venous devices. CT scan is the key examination for the exploration of SVCS. It specifies the characteristics of the stenosis, its aetiology and detects collateral venous routes. Scannography reconstructions provide a true map of the obstacle, indispensable in planning the endovascular treatment.
上腔静脉综合征 (SVCS) 是指所有因上腔静脉引流受阻和上游静脉压力增加而引起的征象。SVCS 有两个主要病因：恶性，主要由支气管肺癌引起；良性，通常继发于位置不当的植入式静脉装置。CT 扫描是探索 SVCS 的关键检查。它可明确狭窄的特征、病因，并发现侧支静脉通路。扫描重建提供了障碍物的真实图谱，对于血管内治疗的计划至关重要。
