目的：探讨多层螺旋 CT 血管造影（MSCTA）在睾丸动脉（TA）起源变异的影像表现，提高对该血管变异的认识，为睾丸病变的治疗提供帮助。方法：回顾性分析行全腹部及盆腔多层螺旋 CT 增强扫描的正常成年男性250例，采用容积重组（VR）血管生长技术（AV）进行血管重建，观察 TA 异位开口的发生率、起始血管及部位。结果：250例 TA 中共223例双侧 TA 显影，显影率89．2％（223/250），19．3％（43/223）异位开口。一侧开口异常41例，其中6．3％（14/223）异位开口于肾主动脉或分支，5．4％（12/223）异位开口于肾副动脉或分支，4．0％（9/223）异位开口于肾动脉水平上方腹主动脉前外侧壁，2．7％（6/223）异位开口于肠系膜下动脉水平下方腹主动脉前外侧壁；1例双侧开口异常，均开口于肾主动脉或分支；另1例右侧双支动脉供血。结论：采用 VR AV 最能清楚、准确、直观地显示 TA 的起源变异情况。
目的：探討多層螺鏇 CT 血管造影（MSCTA）在睪汍動脈（TA）起源變異的影像錶現，提高對該血管變異的認識，為睪汍病變的治療提供幫助。方法：迴顧性分析行全腹部及盆腔多層螺鏇 CT 增彊掃描的正常成年男性250例，採用容積重組（VR）血管生長技術（AV）進行血管重建，觀察 TA 異位開口的髮生率、起始血管及部位。結果：250例 TA 中共223例雙側 TA 顯影，顯影率89．2％（223/250），19．3％（43/223）異位開口。一側開口異常41例，其中6．3％（14/223）異位開口于腎主動脈或分支，5．4％（12/223）異位開口于腎副動脈或分支，4．0％（9/223）異位開口于腎動脈水平上方腹主動脈前外側壁，2．7％（6/223）異位開口于腸繫膜下動脈水平下方腹主動脈前外側壁；1例雙側開口異常，均開口于腎主動脈或分支；另1例右側雙支動脈供血。結論：採用 VR AV 最能清楚、準確、直觀地顯示 TA 的起源變異情況。

Objective:To investigate the multi-slice CT angiography (MSCTA)appearances of the origin of testicular artery (TA),in order to improve the understanding of that blood vessel anomaly,provides assistance for the treatment of testicular diseases.Methods:The whole abdominal and pelvic MSCTA of 250 healthy male adult subjects were analyzed ret-rospectively.Volume rendering (VR)and add vessel (AV)techniques were adopted for reconstruction of blood vessels,the incidence rate and location of TA origin were studied.Results:Of the 250 cases,bilateral TA could be assessed in 223 cases, with the displaying rate as 89.2% (223/250 cases).The incidence rate of abnormal origin was 19.3% (43/223 cases).41 cases had unilateral abnormal origin,with 6.3% (14/223 cases)had the abnormal opening located at renal artery or it's branches,5.4% (12/223 cases)opened at renal accessory arteries or their branches,4.0% (9/223 cases)opened at the an-terior-lateral wall of the abdominal aorta which was above the level of renal artery,and 2.7% (6/223 cases)opened at the anterior-lateral wall of the abdominal aorta below the level of inferior mesenteric artery.1 case had bilateral obnormal open-ings,located at renal arteries or their branches.Another 1 case had right side double arteries feeding.Conclusions:Abnormal TA origin can be clearly and precisely displayed by VR and AV techniques.
