A cuffing technique and a standard interrupted suturing technique of microarteriorrhaphy were compared in the rat femoral artery. The comparison was based on hemodynamic variables, which were measured by 20-MHz pulsed ultrasound Doppler velocity meter (PUDVM) method. The hemodynamic variables included measured blood velocity and vessel lumen diameters, and calculated volumetric flows. Measurements were completed at 5-, 10-, and 20-minute intervals after vessel repair. Data from 26 experimental animals were suitable for analysis, with 15 animals in the standard repair group and 11 animals in the cuffed group. All variables were statistically similar prior to the surgical procedure, indicating that the study groups were appropriate for comparison. The measured lumen diameters were not statistically different at any time interval (P = .06). However, the velocities and the volumetric flow were statistically different (P less than .05) between groups at all time intervals. These values returned toward normal preoperative values over time. The cuffing technique used in this study was not as efficacious as the standard technique of microarteriorrhaphy, when evaluated by 20-MHz PUDVM-derived hemodynamic criteria.
在大鼠股动脉中，对一种套扎技术和标准的显微动脉缝合间断缝合技术进行了比较。该比较基于血流动力学变量，这些变量通过20兆赫脉冲超声多普勒测速仪（PUDVM）方法进行测量。血流动力学变量包括测量的血流速度和血管腔直径，以及计算的容积流量。在血管修复后的5分钟、10分钟和20分钟间隔完成测量。来自26只实验动物的数据适合进行分析，标准修复组有15只动物，套扎组有11只动物。在手术过程之前，所有变量在统计学上相似，表明研究组适合进行比较。在任何时间间隔，测量的管腔直径在统计学上没有差异（P = 0.06）。然而，在所有时间间隔，两组之间的速度和容积流量在统计学上有差异（P小于0.05）。这些值随时间恢复到术前的正常水平。当通过20兆赫PUDVM得出的血流动力学标准进行评估时，本研究中使用的套扎技术不如标准的显微动脉缝合技术有效。
