Forty-five end-to-side microvascular anastomoses were completed in rat carotid arteries of 0.7-0.8 mm diameter (anastomosing the distal end of the left common carotid to the side of the right common carotid). For comparison both 10-0 and 11-0 sutures were utilized in different anastomotic techniques: interrupted, direct-continuous, and diagonal-continuous sutures, plus total mural thickness vs. partial mural thickness (piercing only the adventitia and outer media, excluding the intima). Anastomoses were evaluated for patency and scanning electron microscopic appearance after 10 to 12 weeks. The results indicate complete patency in all anastomoses. Ultrastructural observations revealed nearly normal intimal appearance in the partial medial technique and only minimal evidence of intimal injury in the other techniques. It is concluded that 100% patency can be obtained regardless of suture size or anastomotic technique. The most important factor in anastomotic patency is the operator's technical skill.
在直径为0.7 - 0.8毫米的大鼠颈动脉上完成了45例端侧微血管吻合术（将左颈总动脉的远端与右颈总动脉的侧面吻合）。为了进行比较，在不同的吻合技术中使用了10 - 0和11 - 0缝线：间断缝合、直接连续缝合和斜向连续缝合，以及全壁厚度与部分壁厚度（仅穿透外膜和外中层，不包括内膜）。在10至12周后评估吻合口的通畅性和扫描电子显微镜外观。结果表明所有吻合口均完全通畅。超微结构观察显示，部分中层技术的内膜外观几乎正常，其他技术仅显示极轻微的内膜损伤迹象。得出的结论是，无论缝线尺寸或吻合技术如何，均可实现100%的通畅率。吻合口通畅的最重要因素是操作者的技术技能。
