All surgical intervention need skin incision. Section of afferent vessels can cause skin necrosis. The knowledge of skin vascularization can be helpful for surgeons to avoid complications. The most important study on the arteries of the skin was performed in 1936 by Salmon. He performed dissection associated to radiography of the skin. This technique that was innovative at the time presented some limits and many questions remained unsolved. Thanks to the new imaging technology (Hight resolution CT scan) associated to the dissections of the specimens we can obtain more data about arteries of the skin. The aim of our study was to demonstrate the feasibility of guided CT scan dissections of the arteries of the skin. MATERIALS AND METHODS In 10 cadaver dissections of the lower extremity were performed. A barium sulfate suspension (Micropaque ® ) with colored liquid latex (25%: 75%) was injected under low pressure via femoral artery. Two days after the injection, a CT scan of the specimen was performed using a 64‐row MDCT (Lightspeed, General Electric Healthcare, Milwaukee, USA). Image processing and compilation of MDCT data were used to reconstruct the images in curvilinear two‐dimensional modes: multiplanar reconstruction (MPR) and voluminal surface three dimensional modes: maximum intensitity projection (MIP). As a second step we dissected the arteries and marked the skin vessels guided by the CT images MPR and MIP. RESULTS The CT scan of the legs allowed us to identify the principal arteries of the skin and to planify the dissection. The guided CT dissection allowed us to performed the dissections paying attention to the afferent arteries et to show the course of the vessels in order to avoid a bad manipulation of the specimens. CONCLUSIONS The guided CT scan dissections of the legs is faisable and can be helpful for the study of skin arterial network with 3D visualization of afferternt arteries.
