The telescoping anastomotic technique was used for both anastomoses of vein grafts placed in the rat left epigastric vein in an effort to make the anastomosis easier and faster. Vein grafting in the right epigastric vein was completed using the conventional technique. The 20 rats with 20 left and 13 right vein grafts, which were patent at 3 weeks, were seen again 3 months postoperatively to compare the two techniques with regard to long-term stenosis and histological changes. Patency of the grafts 2 hr postoperatively was also compared between the two techniques in another 25 rats to eliminate the influence of recanalization on patency. All the vein grafts, which had been patent 3 weeks postoperatively, remained patent after 3 months and no statistically significant difference was found between the telescoping and conventional technique in the degree of stenosis. The vein grafts 2 hr postoperatively were all patent in both groups.
为使吻合更容易、更快，在大鼠左腹壁静脉植入静脉移植物的两次吻合中均采用了套叠吻合技术。右腹壁静脉的静脉移植采用传统技术完成。20只大鼠植入了20根左静脉移植物和13根右静脉移植物，术后3周时这些移植物均通畅，术后3个月再次观察，以比较两种技术在长期狭窄和组织学变化方面的情况。在另外25只大鼠中比较了两种技术术后2小时移植物的通畅情况，以消除再通对通畅的影响。所有术后3周通畅的静脉移植物在3个月后仍保持通畅，套叠技术和传统技术在狭窄程度上无统计学显著差异。两组术后2小时的静脉移植物均通畅。
