摘要

後腹腔纖維化是一種不明原因之罕見疾病，其特徵為纖維化腫塊包圍脊椎周圍之結構。下腔靜脈阻塞引起下肢深部靜脈栓塞是一罕見之併發症。下腔靜脈阻塞合併下肢旁系循環之診斷，高轉速之電腦斷層已取代傳統之下腔靜脈攝影，因其近乎等向的資料取得及高解析度之冠狀及矢狀切面，容積再現技術對治療病人方式的選擇有很大的幫助。

並列摘要

Idiopathic retroperitoneal fibrosis is a rare disease of unknown etiology characterized by fibrous mass or plaque in the retroperitoneal area that envelops the paravertebral structures. Occlusion of inferior vena cava (IVC) and deep veins of the lower leg causes deep vein thrombosis (DVT), but is a rare complication. High speed multidetector computed tomography (MDCT) has the potential to replace traditional venography and conventional computed tomography in the evaluation of IVC occlusion, especially in the demonstration of collateral circulation of the lower trunk. It provides near-isotropic data, superior spatial resolution, corona and sagittal reconstruction, and 3 dimensional volumetric rendering information which would be helpful for the therapeutic intervention.
