The purpose of this study was to compare interrupted and continuous suturing techniques in laboratory microarteriorrhaphy. The comparison was based on rat femoral artery hemodynamic variables, including blood velocities, lumen diameters, and calculated blood flow. These variables were calculated by an offline computer from Doppler frequency shifts that were measured by a 20-MHz pulsed ultrasonic Doppler velocity meter. No statistical difference was noted postoperatively between the interrupted and continuous techniques relative to any hemodynamic variable. Average blood flow after the interrupted (n = 12) and continuous (n = 12) techniques was 6.59 +/- 1.12 and 6.74 +/- 1.20 ml/min, respectively. The two microarteriorrhaphy techniques result in equal postoperative vessel hemodynamics in a laboratory model.
本研究的目的是在实验室微动脉缝合术中比较间断缝合法和连续缝合法。该比较基于大鼠股动脉血流动力学变量，包括血流速度、管腔直径和计算得出的血流量。这些变量由一台离线计算机根据20兆赫脉冲超声多普勒测速仪测量的多普勒频移计算得出。术后，间断缝合法和连续缝合法在任何血流动力学变量方面均未发现统计学差异。间断缝合法（n = 12）和连续缝合法（n = 12）术后的平均血流量分别为6.59±1.12毫升/分钟和6.74±1.20毫升/分钟。在实验室模型中，这两种微动脉缝合技术产生相等的术后血管血流动力学效果。
