Background: Liver transplantation is the only one radical treatment for end stage liver diseases in children. For children with body weight below 15 kg we used left lateral section graft. function living donor (LDLT) depends on adequate blood inflow and outflow. this reason vascular reconstruction important part of LDLT. Vascular anatomy recipient may vary define type venous reconstruction. Goal study to evaluate anatomical variants systemand indications Materials methods: Results 31 LDLT were analysed. Evaluated size mismatch ratio between portal vein (PV) branches PV trunk was 1,5-2,5. Initial thrombosis observed 3,2%(1 case). Result: Left middle hepatic donors estimated according Nakamura Tsuzuki classification. We divide all types donor's veins four groups: 1) common orifice Sg2-3 length over 5 mm (61,3%) 2) less then (9,7%) 3) two separate orifices Sg2 Sg3 distance them (19,4%) 4) Single vein, acceptable standard reconstruction, 61,3% (19 cases). In 51,6% (16 cases) pediatric perform or more methods. Discussion: recipient, absence (LLS), presence initial are indication To achieve portoplasty autovenous patch, cavaportal transposition, plastic confluence by patch ovarian vein. outflow autovenos LLS veins, shaping separately incoming Sg 2, 3 harvesting MHV. Conclusion: Ours technics cases, where methods anatomically impossible, improve results paediatric
