| More Details: | Backgrounds The quantified relationship between perforator diameter and flap length can be supported, and the impact of different strategies of managements of a non-pedicled perforator with two major subfascial divisions on flap survival has never been explored. Materials and methods This study was divided into two parts. In Part I, 48 Sprague-Dawley rats underwent flap harvesting based on six perforators with a diameter gradient. Then, the flap length and perforator diameter were measured for establishment of an equation. In Part II, 32 rats underwent harvest of a transverse flap based on the right superficial epigastric perforator. In 16 rats the right intermediate iliolumbar perforator was severed in a distal-to-division approach, whereas, in the other 16 rats, it was severed with in a proximal-to-division approach. Necrosis rates and blood perfusion were also compared. Results The equation y = 13.02 × x + 2.29 could be established between the perforator diameter in the pedicle (x) and the flap length (y) that could be supported with R2=0.8963 and P < 0.001.The transverse flap with a distal-to-division management of the intermediate iliolumbar perforasome was weaker in perfusion and had a necrosis rate of 49±4%, whereas the flap with a proximal-to division management had a significantly stronger perfusion and a lower necrosis rate of 21±2% (P |
