Abstract (original English)

Aim Fat transfer is commonly used to fill loss of volume in depressed scars caused by trauma, deep burns or surgery. The aim of the study is to investigate the degree of fat graft take through evaluation of the microcirculation of grafted autologous adipose tissue using contrast-enhanced ultrasonography. Patients and method From 2010 to 2012 at the Department of Plastic and Reconstructive Surgery of the Traumatological Center in Turin, a study population was selected from patients with surgical indications for autologous fat transfer for scar correction. For each surgical procedure patients underwent a clinical and sonographic evaluation before and after intervention (at 1 month and 3 months). Results Out of a total of 28 interventions, 24 showed a good result; defined as improvement of the scar, and confirmed by the presence of vascularization in the transplanted tissue. In 4 cases, there was a lack of blood supply at the first evaluation but an initial good clinical scar correction. The absence of blood vessels was confirmed at 3 months accompanied by complete resorption of the transferred fat with a failure of good clinical outcome. Conclusion Contrast-enhanced ultrasonography was able to evaluate the microvasculature of adipose tissue after fat transfer. Due to this characteristic, it allows to monitor and predict the take of adipose tissue and provide realistic and early i
