[Experimental study on the role of the pedicle of the subdermal vascular network skin flap].

Objective: The experiment was to investigate the role of the pedicle of the subdermal vascular network skin flap.

Methods: Ten healthy white pigs, weighting from 20 to 25 kg were used. The subdermal vascular network skin flap and the traditional skin flap were designed and created on each side of the animal's flank. The traditional skin flap on the contralateral side of the flank was used as control. Flap survival was studied by gross observation and ECT examination of isotope distribution.

Results: There were significant differences between the two groups in mean survival length and area (P < 0.05). In both groups the radioactive isotope gathering is restricted proximally with a ratio of length to width of (1-1.5):1.

Conclusion: The presence of the pedicle of the subdermal vascular network skin flap makes no difference compared the traditional skin flap.
