AB  - A series of 240 diode laser assisted end-to-end microvascular anastomoses (LAMA) 
      and conventional manual anastomoses (CMA) were performed in the left and right 
      common carotid of Wistar rats, respectively. In comparison with the two 
      anastomotic methods, optic and scanning electron microscopic examinations were 
      achieved from Day 0 to Day 210, in order to clarify the mechanism of media repair 
      after diode laser welding, especially the long-term results. In the LAMA group, 
      the cut vessel edges were welded without obvious thermal necrosis after laser 
      treatment. On Day 10, media repair was underlined by circular bulges 
      corresponding to the folds of cut vessel endings brought together. Inflammatory 
      cells were regularly scattered in the adventitia in the vicinity of the 
      anastomotic site, and were gaining ground intensively in the media by Day 20. At 
      this time, the parallel organization of elastic laminae disappeared while the 
      collagen network developed. On Day 120, irregular elastic fibres aggregated in 
      the anastomotic site. On Day 210, reconstituted elastic lamina was present. In 
      the CMA group, on Day 20, fibrotic repair appeared between cut vessel edges, and 
      the injury incorporated by sutures was important. The elastic laminae were not 
      reconstituted by Day 210 in any case. This microscopic study proves that the 
      long-term repair of diode LAMA facilitates media repair and prevents fibrotic 
      scarring of the media.
