摘　要:目的分析高频超声（HFUS）检测膨体聚四氟乙烯（e-PTFE）材料包裹动脉瘤的声像图特点和血流变化情况,初步探讨超声技术在实验性动脉瘤包裹治疗术中的价值。方法应用HFUS检测e-PTFE包裹治疗犬颈部动脉瘤过程中不同时间于包裹动脉瘤腔、吻合口和载瘤动脉的内径、血流速度以及阻力指数并与未包裹侧动脉瘤模型相对照。结果HFUS可清晰地显示包裹动脉瘤大小、前后壁、夹层以及吻合口、瘤腔、载瘤动脉之血流动力学改变。e-PTFE片包裹治疗成功率为（7/8）87.50%,与数字减影血管造影（DSA）结果相互印证。结论e-PTFE对实验性梭形动脉瘤包裹治疗有较高的成功率,HFUS可作为影像学动态检测的最佳方法。[著者文摘]
