Abnormal development of the inferior vena cava is a relatively rare condition. We report the case of a 47-year-old woman presenting with an absent infrarenal segment of the inferior vena cava revealed by recurring episodes of gross hematuria. This entity probably resulted from perinatal acquired thrombosis rather than from a congenital anomaly and is associated with compensatory dilation of collateral venous pathways. This extremely rare hemorrhagic presentation is presumably caused by rupture of small dilated renal or vesical veins. Ignorance of this atypical presentation can lead to erroneous or delayed diagnoses.
下腔静脉发育异常是一种相对罕见的病症。我们报告了一例47岁女性病例,该患者反复出现肉眼血尿,检查发现其肾下段下腔静脉缺如。这种情况可能是围产期获得性血栓形成所致,而非先天性异常,并且与侧支静脉通路的代偿性扩张有关。这种极为罕见的出血表现可能是由扩张的肾静脉或膀胱静脉小分支破裂引起的。对这种非典型表现的忽视可能导致错误诊断或诊断延误。
