彩超在腹主动脉瘤腔内隔绝术后的应用价值

目的：探讨彩色多普勒血流显像（CDFI）在腹主动脉瘤腔内隔绝术后的应用价值，方法：应用CDFI对18例行腹主动脉瘤腔内隔绝术的患者术后进行随访。结果：CDFI显示所有患者人造血管内血流通畅。6例患者术后后瘤腔内显示出异常血流，诊断为内漏。12例无内漏患者后瘤体内径随随访时间延长逐渐变小；6例内漏患者中，2例瘤体内径缩小，2例无明显变化，2例略增大，结论：CDFI可对腔内隔绝术后手术疗效进行准确判断。及时发现并发症，是术后随访的首选检查方法。

Application of color Doppler flow imaging after abdominal aortic aneurysm endovascular graft exclusion

Objective To evaluate the value of color Doppler flow imaging (CDFI) after abdominal aortic aneurysm endovascular graft exclusion.Methods Eighteen patients after abdominal aortic aneurysm endovascular graft exclusion were followed up by CDFI.Results In all follow up patients,CDFI displayed the vascular prostheses were patent.Six patients with abnormal flow in the aneurysm sac were diagnosed as endoleaks.The aneurysm diameter of twelve patients without endoleak reduced gradually along with increased follow up time.Of the six patients with endoleaks,the aneurysm diameters of two patients didn't change significantly,that of two reduced and two increased slightly.Conclusions CDFI can accurately assess the curative effect of abdominal aortic aneurysm endovascular graft exclusion and detect its complications in time,so that it is the first choice of follow up examination methods.
