Background: Whole liver transplantation in infants <10 kg is a rare procedure with moderate outcomes (67%–79% graft survival at 1 year) and high rates of vascular complications (hepatic artery thrombosis 5–26%). Methods: Retrospective single‐center analysis of whole liver transplantation in infants <10 kg and systematic review of the literature focused on survival rates and surgical complications. Results: Between January 2005 and December 2020, 175 liver transplantations in 173 children were performed at our center. A total of 92 (53%) children weighed less than 10 kg; 19 (21%) of them underwent WLT and constitute the study population. Median age of the recipients was 10 months (21 days–24 months) and median body weight 6.5 (3.1–9.8) kg. Median age of the donors was 5 (1–84) months and median body weight 6.1 (4–21) kg. Median donor‐to‐recipient body weight ratio was 1.2 (range: 0.6–4.5). Postoperatively, neither hepatic artery nor portal vein thrombosis occurred. A biliary complication occurred in 4 cases: 1 bile leak (early), 3 anastomotic stenoses (1 delayed and 2 late), and 1 non‐anastomotic stenosis (late). Patient survival rate at 1, 5, and 10 years was 100%, 92%, and 92%, respectively. Overall, death‐censored graft survival after 1, 5, and 10 was 100%. Conclusion: Our results are excellent in terms of complications and graft and patient survival. This involves not only high‐end surgical performance but also close interdisciplinary perioperative cooperation based on strong standard operating procedures and mainly focused on fluid management, hemostasiology, and strict monitoring of vessel patency.
