Abstract:
Objective To reveal the relationship between a certain ratio of the length to width of a slender narrow pedicle and random flap in survival area with an experimental study. Methods 25 pigs were randomly divided into 5 groups. The ratio of length to width of slender narrow pedicle in 5 groups was different and every ratio's slender narrow pedicle was carrying 5 different sizes of random flaps. In each group, these 5 flaps were created randomly in each pigs' bilateral back. The flaps were evaluated with the general observation, fluorescence examination, blood flow ECT test, and computerized analysis of survival area. Results When the ratio of the length to width of the slender narrow pedicle was constant, along with the flap area increased, the flap survival area also increased, but when the flap reached a certain area, the distal flap would develop necrosis, the flap survival area would not reduce; when the flap size remained unchanged, along with the ratio of the length to width of the slender narrow pedicle increased, the flap survival area was not affected, but, when the ratio of the length to width of the slender narrow pedicle increased to a certain limit, distal flap would lead to necrosis, and the flap survival area would reduce. Conclusion The slender narrow pedicle flap is a new and practical random flap. The pedicle of random flap can be designed as slender shape, and the ratio of pedicle width to flap length is far less than traditional ratio. Increasing the flap size or ratio of the length to width of a slender narrow pedicle in a certain extent will not lead to flap necrosis.
