The absence of the inferior vena cava is a rare congenital anomaly. Currently its diagnosis is based on non-invasive imaging techniques (computerised axial tomagraphy and nuclear magnetic resonance). In most cases, it constitutes a casual finding upon practising these image tests unrelated to this congenital anomaly. In the symptomatic patients, the complaints associated are secondary to venous insufficiency and/or deep vein thrombosis. Recently the congenital absence of inferior vena cava has been described as a risk factor of deep vein thrombosis in young patients. We present a case of congenital absence of inferior vena cava that was admitted in our hospital because of pulmonary thromboembolism.
下腔静脉缺如是一种罕见的先天性异常。目前其诊断基于非侵入性成像技术（计算机断层扫描和核磁共振）。在大多数情况下，它是在进行这些与该先天性异常无关的影像检查时偶然发现的。有症状的患者，相关主诉继发于静脉功能不全和/或深静脉血栓形成。最近，先天性下腔静脉缺如被描述为年轻患者深静脉血栓形成的一个危险因素。我们报告一例因肺血栓栓塞入住我院的先天性下腔静脉缺如病例。
