[Experimental study on revascularization of subdermal vascular network thin flap].
OBJECTIVE
To investigate the survival mechanism of subdermal vascular network thin flap (SVNF).


METHODS
24 rabbits were divided into three groups, in which the SVNF, subdermal vascular network skin graft and the traditional random flap were created respectively. Tissue hyalinization technique was used to find out the differences of vascular architecture between the three groups at the 1st-7th day, and the 14th day postoperatively.


RESULTS
The results showed that the blood supply reestablished earlier in SVNF group than the other two groups.


CONCLUSIONS
There is a zone of rapid and intensive angiogenesis in the mid-part of SVNF known as "intermediary pedicle". This is the anatomic basis of the early pedicle division and superior survival ratio of SVNF.
