本研究的目的是确定腹主动脉瘤腔内修复后动脉瘤体积的变化。MethodsA共154例连续患者接受腹主动脉瘤腔内修复与美敦力AneuRx覆膜支架在斯坦福大学医院进行了评价。在平均15.8 ± 11.3个月的随访期内，对螺旋计算机断层扫描数据集进行了动脉瘤体积和正交最大直径的连续计算机测量，并根据横向计算机断层扫描图像手动测量了最大横向直径。主动脉髂动脉长度（肾下腹动脉起源）测量沿着正中管腔中心线和沿着the straight line.ResultsAneurysm体积增加后立即腔内修复术（从180.2 ± 69.9 mL到187.9 ± 71.6 mL; P <0.001），但正交和横向直径和髂动脉长度没有显着变化。在随访期间，平均体积降至171.9 ± 70.2 mL（P <0.05），直线和中心线髂髂动脉长度与术前值相比保持不变。总体而言，容量以1.7 ± 5.9 mL/mo的速率下降（P < .001）。在无内漏期间，减少率为3.2 ± 5.5 mL/mo（P <0.001），在有内漏期间，动脉瘤体积以2.0 ± 5.3 mL/mo（P <0.005）的速率增加，内漏类型之间无差异。横向和正交直径和体积的内漏预测值相似。Logistic回归分析显示，体积是最密切相关的存在endoleak.ConclusionAneurysm体积增加后立即腔内修复术。修复后，动脉瘤体积逐渐减小，髂动脉长度保持不变。体积变化与最大动脉瘤直径变化平行，其与内漏存在的相关性似乎并不明显更强。（J Vasc Surg 2002;36：305-9.）
ObjectiveThe purpose of this study was to define changes in aneurysm volume after endovascular repair of abdominal aortic aneurysm.MethodsA total of 154 consecutive patients who underwent endovascular repair of abdominal aortic aneurysm with the Medtronic AneuRx stent graft at Stanford University Hospital were evaluated. During a mean follow-up period of 15.8 ± 11.3 months, serial computerized measurements of aneurysm volume and orthogonal maximal diameter were performed on helical computed tomographic scan data sets and maximal transverse diameter was measured manually from transverse computed tomographic images. Aortoiliac length (renal to hypogastric artery origin) was measured along the median luminal centerline and along the straight line.ResultsAneurysm volume increased immediately after endovascular repair (from 180.2 ± 69.9 mL to 187.9 ± 71.6 mL; P < .001), but orthogonal and transverse diameter and aortoiliac length did not change significantly. During the follow-up period, mean volume decreased to 171.9 ± 70.2 mL (P < .05) and straight-line and centerline aortoiliac length remained unchanged from preoperative values. Overall, volume decreased at a rate of 1.7 ± 5.9 mL/mo (P < .001). During periods without endoleak, the rate of decrease was 3.2 ± 5.5 mL/mo (P < .001), and during periods with endoleak, aneurysm volume increased at a rate of 2.0 ± 5.3 mL/mo (P < .005), without a difference between types of endoleak. Predictive values for the presence of endoleak were similar for transverse and orthogonal diameter and volume. Logistic regression analysis showed volume to be most closely associated with the presence of endoleak.ConclusionAneurysm volume increases immediately after endovascular repair. After repair, aneurysm volume gradually decreases and aortoiliac length remains unchanged. Changes in volume parallel changes in maximal aneurysm diameter, and their association with the presence of an endoleak does not appear to be appreciably stronger. (J Vasc Surg 2002;36:305-9.)
