Donor hepatic artery thrombosis (dHAT) identified during liver procurement and backtable is a rare and little-reported event that can make liver transplants unfeasible.Methods. This is a retrospective study of dHAT identified during liver grafts procurements or backtable procedures. All grafts were recovered from brain-dead donors. The demographic characteristics of the donors and the incidence of dHAT were analyzed. The data were also compared to a cohort of donors without dHAT.Results. There was a total of 486 donors during the study period. The incidence of dHAT was 1.85% (n = 9). The diagnosis of dHAT was made during procurement in 5 cases (55.5%) and during the backtable in 4 (44.4%). Most donors were female (n = 5), with an average BMI of 28.14 </n> 6.9 kg/m2, hypertensive (n = 5), and with stroke as cause of brain death (n = 8). The most prevalent site of dHAT was a left hepatic artery originating from the left gastric artery (n = 4). Of the 9 cases reported, 2 livers were used for transplantation, and 7 were discarded. Comparing those cases to a cohort of 260 donors without dHAT, we found a higher incidence of anatomic variations in the hepatic artery (P = .01) and of stroke as cause of brain death (P = .05).Conclusion. The occurrence of dHAT before liver procurement is a rare event, however it may become a treacherous pitfall if the diagnosis is late. Grafts with anatomic variations recovered from women with brain death due to stroke and with past history of hypertension seem to be at a higher risk of presenting dHAT.engrestrictedAccessarticleCopyright ELSEVIER SCIENCE INC10.1016/j.transproceed.2022.04.003ImmunologySurgeryTransplantation1873-2623
