In search of the "perfect" anastomosis.

摘要: Forty-five end-to-side microvascular anastomoses were completed in rat carotid arteries of 0.7-0.8 mm diameter (anastomosing the distal end left common to side right carotid). For comparison both 10-0 and 11-0 sutures utilized different anastomotic techniques: interrupted, direct-continuous, diagonal-continuous sutures, plus total mural thickness vs. partial (piercing only adventitia outer media, excluding intima). Anastomoses evaluated for patency scanning electron microscopic appearance after 10 12 weeks. The results indicate complete all anastomoses. Ultrastructural observations revealed nearly normal intimal medial technique minimal evidence injury other techniques. It is concluded that 100% can be obtained regardless suture size or technique. most important factor operator's technical skill.
