Abstract

Objective To evaluate the value of multi-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 in the low extremity artery.Images were analyzed on the basis of the transverse CT source data including volume rendering(VR) and multiplanar reconstruction(MPR) and curved planar reconstruction(CPR) 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. Conclusion 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.

Introduction

随着人们生活水平的改善和人口老年化的日益增加，下肢血管的各种疾病在日常的诊断中日益多见，其中以下肢动脉硬化为主要病因的下肢动脉栓塞更是威胁着很多患者的健康，而下肢人工血管搭桥、旁路移植在这方面很好的解决了病患的痛苦[1]，然而，随着时间的推移，人工血管的通畅程度成为了医患共同担心的问题。为此，寻找一种简单、有效、安全的方法进行人工血管植入术后的评价就有了重要意义。以往该病的影像诊断是通过DSA、彩超等方式进行，然而DSA为有创性检查，彩超分辨率低，检查价值有限。本研究在于探讨64层螺旋CT血管造影在下肢血管人工植入术后评价通畅程度的价值。
