This study aims to demonstrate the clinical advantage of Nevelia\u00ae, an innovative collagen dermal template substitute (DS) in venous and arterial chronic ulcers treatment. 35 patients affected by chronic vascular ulcers with a mean area of 35.1 \u00b1 31.8 cm2 were treated with DS followed by autologous dermal epidermal graft (DEG). Follow-up was performed at 7-14-21 and 28 days after DS implant and 7-14-21 and 28 days after DEG. At 28 days after DEG, the mean values of Manchester Scar Scale was of 1.8 \u00b1 0.7 for skin color, 1.6 \u00b1 0.7 for skin contour, 1.7 \u00b1 0.7 for distortion, and 1.7 \u00b1 0.7 for skin texture, whereas skin was matte in 27 patients (77%) and shiny in the remaining eight cases (23%). Histological findings correlate with the clinical result showing a regenerated skin with reactive epidermal hyperplasia and dermal granulation tissue after two weeks (T1), and after three weeks (T2) a re-epithelialization and a formed new tissue architecture analogue to normal skin physiology. These data suggest that Nevelia\u00ae could be useful to treat chronic venous and arterial ulcers.<\/jats:p>","DOI":"10.3390\/jcm8040525","type":"journal-article","created":{"date-parts":[[2019,4,17]],"date-time":"2019-04-17T07:58:09Z","timestamp":1555487889000},"page":"525","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Vasculogenic Chronic Ulcer: Tissue Regeneration with an Innovative Dermal Substitute"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1712-6702","authenticated-orcid":false,"given":"Barbara","family":"De Angelis","sequence":"first","affiliation":[{"name":"Department of Surgical Science, Plastic and Reconstructive Surgery Unit, University of Rome Tor Vergata, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabrizio","family":"Orlandi","sequence":"additional","affiliation":[{"name":"Department of Surgical Science, Plastic and Reconstructive Surgery Unit, University of Rome Tor Vergata, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margarida Fernandes Lopes","family":"Morais D\u2019Autilio","sequence":"additional","affiliation":[{"name":"Department of Surgical Science, Plastic and Reconstructive Surgery Unit, University of Rome Tor Vergata, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Di Segni","sequence":"additional","affiliation":[{"name":"Department of Surgical Science, Plastic and Reconstructive Surgery Unit, University of Rome Tor Vergata, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Giovanna","family":"Scioli","sequence":"additional","affiliation":[{"name":"Department of Biomedicine and Prevention, Pathologic Anatomy Institute, University of Rome \u201cTor Vergata\u201d, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Augusto","family":"Orlandi","sequence":"additional","affiliation":[{"name":"Department of Biomedicine and Prevention, Pathologic Anatomy Institute, University of Rome \u201cTor Vergata\u201d, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valerio","family":"Cervelli","sequence":"additional","affiliation":[{"name":"Department of Surgical Science, Plastic and Reconstructive Surgery Unit, University of Rome Tor Vergata, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3123-3977","authenticated-orcid":false,"given":"Pietro","family":"Gentile","sequence":"additional","affiliation":[{"name":"Department of Surgical Science, Plastic and Reconstructive Surgery Unit, University of Rome Tor Vergata, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3S","DOI":"10.1016\/j.jvs.2014.04.049","article-title":"Management of venous leg ulcers: Clinical practice guidelines of the Society for Vascular Surgery\u00ae and the American Venous Forum","volume":"60","author":"Passman","year":"2014","journal-title":"J.
