The strength of various anastomotic techniques was examined in a canine model utilizing a strain gauge to determine the force required to disrupt single/double/multiple sutures placed at 1,2, and 3 mm depth of bite. Pull-out strength was found to be primarily a factor of the plane of preliminary arterial dissection, reflected as the amount of adventitia included in each bite; the depth of the suture was a lesser contributory factor. Pull-out strengths of complete vascular anastomoses were no stronger than their constituent single stitches. An optimal vascular anastomotic technique is therefore advocated.
在犬类模型中，利用应变仪检测了各种吻合技术的强度，以确定破坏置于咬合深度为1、2和3毫米处的单/双/多根缝线所需的力。发现拔出强度主要是初步动脉解剖平面的一个因素，表现为每次咬合中包含的外膜量；缝线深度是一个次要因素。完整血管吻合的拔出强度并不比其组成的单根缝线更强。因此，提倡一种最佳的血管吻合技术。
