RESULTS: Fifteen (28%) of the 54 pediatric liver transplant recipients had a SPSS, and 11 were ligated intraoperatively due to low portal vein flow (PVF). A median increase in PVF of 142 mL/ min (interquartile range 0 to 600 mL/min) was observed after ligation. The left renal vein was ligated in 6 cases (55%) (Fig. 1). Graft survival was 96% during a median follow-up of 1.5 years (interquartile range 0.1 to 3.3 years), with no deaths or retransplantations occurring in the SPSS ligation group. A significantly greater incidence of portal vein thrombosis or stenosis was observed in the ligation group (45% vs 2%; p < 0.001). Post-transplantation reoperation was also more common in the ligation group (36% vs 12%; p 1⁄4 0.049).
