Delineation the anatomy of posterior tibial artery perforator flaps using human cadavers with a modified technique.
Background: To delineate the distribution and course layer of the perforator vessels using a modified technique. Methods: Twelve perforator flaps were obtained from the crura of six fresh adult cadavers. The flaps were randomized into three groups ( n = 4 per group): the full-thickness flap group; t...

Methods: Twelve perforator flaps were obtained from the crura of six fresh adult cadavers. The flaps were randomized into three groups ( n = 4 per group): the full-thickness flap group; the deep fascia-free flap group, and the subcutaneous adipose layer-free group. The flaps were smoothened on a silk screen on a batten frame and the isolated flaps were perfused at a perfusion pressure of 140 mmHg for 10 min via the trunk of the posterior tibial artery. Perforator flaps were photographed using a digital camera and radiographed using a mammography device. The imaging data were processed by digital software system. Results: The mean number of the posterior tibial artery perforator was 4.17 ± 0.94. The three relatively constant perforators varied in the projection points as well as the diameter and the length. The vascular branches and courses of the perforators were clearly visible on the mammograms. Elimination of all the deep fascia or the subcutaneous adipose tissues in the distal portion had no significant impact on the blood supply of posterior tibial artery perforator flaps while the vascular areas of the artery perforators were significantly reduced after the subcutaneous adipose tissue was eliminated in the proximal portion. Conclusions: We developed an effective modified technique for delineating the vascular territory on perforator flaps of different thicknesses. Our results provide significant guidance for clinical surgeons by providing them with more detailed anatomical knowledge of perforator flaps. pubtype: Academic Journal doctype: Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
