Congenital anomalies of the inferior vena cava (IVC) are rare, but recognized, causing deep venous thrombosis. We present a case of a 50-year-old patient with trauma who suffered an intracranial hemorrhage secondary to a fall while on anticoagulation for deep vein thromboses. Venous return from the lower extremities was determined to be through dilated lumbar venous collaterals into the azygous and hemiazygous systems. A second interesting anatomic finding was a hypoplastic left kidney.
先天性下腔静脉（IVC）异常罕见，但已被认识到可导致深静脉血栓形成。我们报告一例50岁的创伤患者，该患者在因深静脉血栓接受抗凝治疗期间摔倒继发颅内出血。下肢的静脉回流经扩张的腰静脉侧支汇入奇静脉和半奇静脉系统。另一个有趣的解剖学发现是左肾发育不全。
