Pancreas Experience with HTK (n=100)
Mean CIT = 9.6hrs (4hrs – 22.9hrs) Less than 12hrs – 77% 12 to 15.9hrs – 18% Greater than 16hrs – 5% No cases of graft pancreatitis or vascular thrombosis due to preservation

Conclusions Strong clinical academic solid organ transplant practice with complete conversion from UW to Custodial HTK in 2003 without any negative effect Improved outcomes using Custodial for Living Donor Liver Transplantation Recommendation for HTK for DCD donors to improve outcomes
