摘　　要：目的探讨多层螺旋CT血管造影在下肢人工血管植入术后评价血管通畅与否的价值。方法 20例行下肢人工血管植入术后患者接受64层螺旋CT下肢血管造影检查,利用容积再现(VR)、多平面重组(MPR)、曲面重建(CPR)、最大密度投影(MIP)等多种后处理重组方法对人工血管进行评价。结果 20例下肢人工血管植入术后的患者人工血管位置及形态均显示清楚,其中5例管腔通畅,9例轻度狭窄,3例中重度狭窄,3例闭塞。结论多层螺旋CT血管造影可清晰地显示下肢人工血管的位置及形态,可以作为下肢人工血管随访评价的首要检查方法。Objective To evaluate the value of nmlti-slice spiral CT angiography（CTA） in following-up imaging of low extremity arteries after artificial vascular graft. Methods 64-slice spiral CT angiography was performed in 20cases with artificial vascular graft m the low extremity artery.hnages were analyzed on the basis of the transverse CT source data including volmne rendering（VR） and multiplanar reconstruction（MPR） and curved planar reconstruction（CPlK） and maximum intensity projection（MIP）. ,Results The site and configuration of artificial vessels of 20 case were clearly displayed,which met the requirement of diagnosis.20 cases with lower limb atherosclerosis,the transplanted vessels were keeping opening in 5,slight stenosis in 9,remarkable stenosis in 3 and obstruction in 3. Concluion 64-slice spiral CT angiography can clearly show the position and the conformation of the artificial vascular graft,which can be used as the primary inspection mehtod in follow-up study after artificial vascular graft in lower extremity.
