Potential approaches to improve the outcomes of donation after cardiac death liver grafts

Table 1 Disadvantages of the different methods

Preservation methods	Disadvantages
Persufflation	Not able to assess the viability of the grafts
Hypothermic perfusion	High cost, not able to assess the viability of the graft
Subnormothermic perfusion	High cost, clinical challenging, not able to assess the viability of the graft
Normothermic perfusion	High cost, clinical challenging, the blood supply, the risk of losing the graft in the case of emboli in the system
Gradual rewarming	High cost, clinical challenging, need an accurate machine to be able to change the temperature and pressure
Abdominal regional perfusion	Ethical challenging
Thrombolytic therapies	Risk of severe bleeding
