摘　　要：目的探讨胸腰段脊髓主要引流静脉回流异常与椎管内静脉高压发病的解剖基础。方法30具成人尸体采用加压灌注后从腹侧重点观察腰静脉、腰升静脉及奇静脉系来源、分布及瓣膜。结果腰静脉变异较大,腰静脉及交通支均未发现静脉瓣。奇静脉起自右腰升静脉,半奇静脉起自左腰升静脉,副半奇静脉收集左侧中、上部肋间后静脉的回流。结论腰静脉、腰升静脉和奇静脉系是脊髓胸腰段静脉回流的主要途径,其狭窄可造成脊髓静脉系的血液淤积,导致椎管内静脉压增高。Objective To investigate the relationship between intravenous hypertension myelopathy syndrome and the abnormality of the spinal veins, Methods The study was performed in 30 adults cadavers. The distributions, origins and valves of the lumbar veins, ascending lumbar veins and azygos veins were observed, The diameters of the above-mentioned veins were measured. Results The lumbar veins, where no valves were observed, were variable. Azygos vein originated from the right ascending lumbar vein and was drained into superior vena cava. Hemiazygos vein originated from left ascending lumbar vein, and collected the blood of left posterior intercostal veins and accessory hemiazygos vein, The lower segment of azygos vein and hemiazygos vein were drained into vena iliac communis and inferior vena cava. Conclusions The lumbar vein, ascending lumbar vein and azygos vein drain the venous blood of the thoracolumbar segment of the spinal cord, The narrow of them can produce the spinal veins congestion and the intravenous hypertension in the vertebral tube.
