Congenital anomalies of the inferior vena cava (IVC) are very rare and extremely diverse, reflecting the complexity of the embryological development of these structures. The variants must be differentiated from pathology, particularly lymphadenopathy, on imaging studies as their presence can affect surgical and interventional procedures in retroperitoneum. We describe two patients with renal cell carcinoma of left kidney and left IVC.
First patient was taken up for left radical nephroureterectomy. During surgery the existence of a transposed left IVC was demonstrated. The second case is a fifty-four-year-old man; abdomen and pelvic CT-scan with coronal maximum intensity projection reconstruction showed a 7 cm heterogeneously enhancing neoformation involving the left kidney with intraparenchymal hematoma and a transposed left IVC.
Preoperative detection of congenital IVC anomalies can prevent morbidity. Once diagnosed, appropriate care must be taken during the operation to expose and define the anatomic anomaly and protect it from injury.
下腔静脉（IVC）先天性异常非常罕见且极为多样，反映了这些结构胚胎发育的复杂性。在影像学研究中，必须将这些变异与病变，尤其是淋巴结病区分开来，因为它们的存在会影响腹膜后手术和介入操作。我们描述了两名患有左肾细胞癌和左IVC的患者。
首例患者接受了左根治性肾输尿管切除术。手术中证实存在左IVC移位。第二例是一名54岁男性；腹部和盆腔CT扫描及冠状面最大强度投影重建显示，一个7厘米的不均匀强化新生物累及左肾，伴有肾实质内血肿和左IVC移位。
术前检测先天性IVC异常可预防并发症。一旦确诊，手术期间必须采取适当措施暴露并明确解剖异常，防止其受到损伤。
