目的 探讨彩色多普勒血流显像 (CDFI)在腹主动脉瘤 (AAA)腔内隔绝术术前的应用价值。方法应用CDFI对 32例AAA患者术前进行检测 ,主要检测内容包括瘤体的大小、瘤体近远端颈的长度、内径及双侧髂总动脉的内径 ;对瘤体、瘤颈及双侧髂总动脉的形态进行观察 ;判断患者行AAA腔内隔绝术的可行性。结果 术前超声诊断的特异性、敏感性均为 10 0 % ,2 3例行手术治疗的患者中 ,术前超声对 2 0例患者术式的选择作出了正确的判断 ,准确率达 86 .9%。结论 CDFI简便、无创 ,在腔内隔绝术前可对AAA进行准确的测量和正确评价 ,以判断手术的可行性
Objective To investigate the value of color Doppler flow imaging (CDFI) before endovascular exclusion of abdominal aortic aneurysm (AAA). Methods CDFI was used to detect 32 cases of AAA patients preoperatively. The main detection contents include the size of the tumor, the length of the proximal and distal neck of the tumor, the diameter of the neck and the diameter of the common iliac artery. The shape of the common iliac artery was observed; to determine the feasibility of AAA endovascular exclusion. Results The specificity and sensitivity of preoperative ultrasonography were 100%. Among the 23 patients undergoing surgical treatment, the preoperative ultrasound had correctly judged the surgical procedure of 20 patients with an accuracy of 86. 9%. Conclusions CDFI is simple and noninvasive, and can accurately measure and evaluate AAA before endovascular exclusion to determine the feasibility of surgery
