Core tip: There are few reviews concerning the feasibility of using marginal liver grafts in living donor liver transplantation (LDLT). We reviewed more than 300 articles, summarized new findings, and confirmed that marginal grafts are a feasible option for expanding options for patients on liver transplant waiting lists in emergency situations in LDLT (e.g., liver failure or hepatic encephalopathy). However, such grafts place the recipients at greater risk for adverse events. Although some indispensable treatments are needed to address the deficiencies of these grafts, recipients can receive a favorable prognosis, similar to that of patients who receive standard liver grafts, under these treatments.
