The main variations were variant left hepatic artery (45.3%) from the gastric artery; variant right hepatic artery (38.5%); and a triple combination of variant right and left hepatic artery and the proper hepatic artery from the common hepatic artery (12.8%); other 3.4%. Patients\/graft survival and arterial complications were not different between SHA and HAV. Incidence of biliary stricture was numerically higher in left hepatic artery variants (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.058) and in variants where no arterial reconstruction was performed (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.001). Operation and arterial warm ischaemia time were longer in the HAV group. The need for intraoperative re\u2010reconstruction was higher in the HAV group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.04).
