Abstract:In the last decade perforator flaps have been used increasingly for different indications. Many regions may serve as donor site. In this respect the posterior thigh region (PTR) has been neglected as a potential donor site for many years. The purpose of this study was to provide complete mapping of perforators supplying the posterior thigh region. Twelve fresh cadaver thighs were prepared injecting diluted acrylic paint into the iliac artery. Thereafter the posterior thighs were dissected from medial to latera… Show more
“…20 The dominant blood supply of this anatomical area originates from the profunda femoris artery. 21 It runs distally and provides at least two perforators (85 percent of cases: three or more perforators) that are distributed evenly between the medial and lateral halves of the thigh.…”

“…Our earlier anatomical studies revealed longer and larger perforators in the posterior thigh region when compared with those in the anteromedial thigh region. 21,22 Previously reported average pedicle length of the PAP flap was 10.6 cm in a cadaveric study versus 9.9 cm in a clinical study ( Table 2). 19,20 In the current study, the average pedicle length was 11.0 cm.…”

“…In our initial experience, this original technique occasionally resulted in limited flap volume and caudal scar migration. Advancing on Allen's aforementioned work and our perforator studies of the leg, [21][22][23][24] we modified the PAP flap geometrically and applied it in a series of breast reconstruction cases.…”
“…In addition, Hupkens et al. (, ) described a way to harden acrylic paint by leaving the limb in dry air for 1 day, followed by freezing for the next 2 days and thawing it for 1 or 2 days.…”
Over the years, various vascular injection products have been developed to facilitate anatomical dissections. This study aimed to compare the most commonly used vascular injection products in fresh-frozen and formalin-embalmed cadaver specimens. An overview of the properties, advantages and limitations of each substance was given, and a comparison of vascular infusion procedures in both preservation methods was made. A literature search was performed in order to identify the most commonly used vascular injection products. Acrylic paint, latex, gelatin, silicone, Araldite F and Batson's No. 17 were selected for the study. One fresh-frozen and one embalmed cadaver forearm were infused with each injection product according to a uniform protocol. The curing time, skin- and subcutaneous tissue penetration, degree of filling of the arterial tree, extravasations, consistency of the injected vessels during dissection, and the costs of each injection fluid were noted. There was a large variation between the injection fluids in processing- and curing time, colour intensity, flexibility, fragility, elasticity, strength, toxicity and costs. All fluids were suitable for infusion. The penetration of injection fluid into the skin and subcutaneous tissue was significantly better in fresh-frozen specimens (P = 0.002 and P = 0.009, respectively), with significantly smaller branches casted (P = 0.004). Vascular infusion of fresh-frozen cadaver specimens results in a significantly better filled coloured arterial tree, enabling more detail to be achieved and smaller branches casted. The biomechanical properties of fresh-frozen soft tissues are less affected compared with formalin fixation. All the injection fluids studied are suitable for vascular infusion, but their different properties ensure that certain products and procedures are more suitable for specific study purposes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
