ABSTRACT
Objective To explore the effectiveness of octreotide therapeutic strategy to attenuate portal hyperperfusion resulted from small-for-size graft in infant liver transplantation.Methods A total of 22 infants received small-for-size liver graft (defined as GV/SLV＜0.5,and GV＜ 150 g) in our hospital from December 2013 to August 2016.Twelve cases (octreotide group) were treated with intravenous octreotide infusion (300 g daily for 24-96 h) to attenuate the portal hyperperfusion after transplantation,and the rest 10 cases given liver transplantation at the early stage did not receive the intervention of octreotide and served as control group.Results The initial portal vein flows (PVFs) in octreotide group and control group were (413.43 ± 76.24) (390.83 ± 107.89) ml/(min 100 g),and there was no significant difference between two groups (P＞0.05).The PVFs on postoperative day (POD) 3 and POD5 in octreotide group and control group were (334.90 ± 96.67) and (441.04 ± 117.41),and (322.20 ± 81.04) and (423.23 ± 100.81) mL/(min 100 g) respectively (P＜0.05 for all).However,there were no significant differences in serum AST and bilirubin levels at four time points (initial,POD3,POD5 and POD7) after transplantation between two groups (P＞0.05).The incidence of hepatic artery occlusion,and biliary complications in octreotide group and ontrol group was 33.33％ and 44.44％,and 33.33％ and 11.11％ respectively (P ＞ 0.05 for all).Conclusion Octreotide treatment attenuated portal hyperperfusion resulted from small-for-size graft in infant liver transplantation.However,the effects of octreotide therapy on graft biochemical tests,the hepatic artery and biliary complications were still unclear,and further investigation is needed.
