Abstract

Objective To construct a standard method of hierarchical anatomy and localization of perforating vessels based on digital anatomy technology, so as to provide reference for morphological research of perforating vessels. Methods Five donated adult fresh specimens were performed via systemic arterial: two of them with red latex-carboxymethyl cellulose suspension and the left three with lead oxide-red latex-carboxymethyl cellulose suspension. After specimen perfusion, the former was used for gross level anatomy, while the latter was scanned by multiple row spiral CT (MDCT), and then the image workstation (MIMICS, Materialise, Belgium) was used to establish a digital anatomical model of the flap, followed by gross hierarchical dissection. Results The blood vessels of the specimen are well filled, with continuous and smooth edges, and no cavitation or interruption. The subdermal vascular network, cutaneous nerves and their nutrient vascular chains were clearly visible. The main trunk of blood vessels, large and small branches of the three-dimensional image were clear, with stunning 3D effect and without tooth-like artifacts. Conclusions ① The three elements of digital early treatment are alkalization, temperature control and suspension ratio. ② The digital anatomical model of the flap established by Mimics can provide precise hierarchical anatomy and 3D tracking and positioning of the perforator.
