先天性下腔静脉缺失（AIVC）是一种罕见的血管缺陷，通常被报道为偶然发现。由于压缩b超不能检测到AIVC，因此低估了DVT患者AIVC的存在。通过计算机断层扫描，我们在5年的时间里诊断了4例特发性DVT的年轻患者的AIVC。根据同一时期我们地区30岁以下DVT患者的发生情况，我们估计年轻DVT患者中约有5%存在AIVC。计算机断层扫描或血管造影应用于诊断特发性深静脉血栓的年轻患者。
Congenital absence of the inferior vena cava (AIVC) is a rare vascular defect, commonly reported as a fortuitous finding. The presence of AIVC in patients with DVT is underestimated because AIVC cannot be detected by compression B-mode ultrasonography. By use of computed tomography, we diagnosed four cases of AIVC in young patients with idiopathic DVT over a 5 year period. Based on the occurrence of DVT in patients below 30 years In our area during the same period, we estimate that AIVC is present in about 5% of cases of DVT in young patients. Computed tomography or angiography should be used for the diagnosis of idiopathic DVT in young patients.
