摘　　要：目的　探讨忽略腔内血栓的MRA血管重建图像对评估腹主动脉瘤 (AAA)腔内隔绝术(EVE)的影响。方法　比较了 2 0 0 2年 1月至 10月 2 2例行EVE治疗的AAA重建图像与水平位图像的差异。结果　 2 2例AAAMRA水平图像中有 15例 (6 8.2 %)伴腔内血栓 ,可准确评估瘤颈。结论　发现腔内血栓对临床治疗的价值 ,提出了不能单纯依赖三维重建图像 ,应当结合水平位图像共同评估腹主动脉瘤。Objective To investigate the effect of pitfall MRA reconstruction imaging without intraluminal thrombus on endovascular exclusion for abdominal aortic aneurysm. Methods Comparing the MRA reconstruction imaging with the MRA cross-section imaging, all of 22 patients underwent endovascular exclusion from Jan 2002 to Oct 2002 were included. Results Intraluminal thrombus passessed the merit of clinical treatment, otherwise would mislead the evaluation of the procedure. Conclusions It is important to use MRA reconstruction imaging evaluating abdominal aortic aneurysm combining MRA cross-section imaging.
