Blood was withdrawn from the iliac artery and reversed in the portal venous system. An extracorporeal device was interposed between the outflow and the inflow in order to monitoring the hemodynamic parameters. Each treatment lasted 6 hours. Serum and liver samples were collected in both groups.

INR recovered rapidly in the PVA-extracorporeal group remaining significantly lower than in untreated animals. The 7-day survival of PVA-extracorporeal group swine was significantly higher than that of untreated animals, with a statistically significant difference (p&lt;0.05). Four swine in the PVA-extracorporeal group survived at 1 week while none of the swine in the control group were alive at that time; an average time of 144h\u00b113h and 24.4h\u00b15h was observed in the PVA-extracorporeal and control groups, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Arterial blood supply in the portal system through the extracorporeal device is easily applicable, efficacious, safe and may represent a novel approach for ALF swine induced by subtotal liver resection.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/039139880602900912","type":"journal-article","created":{"date-parts":[[2018,1,24]],"date-time":"2018-01-24T11:24:20Z","timestamp":1516793060000},"page":"912-918","source":"Crossref","is-referenced-by-count":5,"title":["An Experimental Pilot Study on Controlled Portal Vein Arterialization with an Extracorporeal Device in the Swine Model of Partial Liver Resection and Ischemia"],"prefix":"10.1177","volume":"29","author":[{"given":"B.","family":"Nardo","sequence":"first","affiliation":[{"name":"Department of Surgery, Intensive Care Unit and Transplantations, S.
