Absence of the entire inferior vena cava was diagnosed by venography, computer tomography and ultrasonography in a 13-year-old boy, who had had dilated superficial abdominal veins since birth. An extensive collateral circulation was found from the left femoral vein, right common iliac vein and the kidneys, through deep abdominal veins, to the azygos vein and superior vena cava. Surgical treatment of this rare abnormality was neither necessary nor advisable.
一名13岁男孩自出生以来腹部浅静脉扩张，通过静脉造影、计算机断层扫描和超声检查诊断为下腔静脉完全缺如。发现存在广泛的侧支循环，从左股静脉、右髂总静脉和肾脏，经腹部深部静脉，至奇静脉和上腔静脉。对这种罕见异常进行手术治疗既无必要也不可取。
