Abstract

Pediatric liver transplantation is an effective last-resort treatment for children with cirrhosis, end-stage liver disease, liver tumors, and certain metabolic diseases. The portal vein characteristics in children with cirrhosis are often small and stenosis as a result of persistent portal hypertension, low portal venous blood flow, or previous surgical interventions. We retrospectively report two cases, a female 16-month-old and a female 4-year-old with the diagnosis: Cirrhosis, end-stage liver disease/Biliary atresia who underwent Kasai surgery with portal vein stenosis who received liver transplantation using left lateral segment from a living donor and replacement of the portal vein with a segment of the external iliac vein from the donor. Postoperative results in both patients were stable, the flow rate through the portal vein was normal, and no stenosis, obstruction, or portal vein thrombosis was detected. Long-term follow-up of 01 patient at the 52th month and 01 patient at the 7th month, clinically stable, portal Doppler ultrasound, flow within normal limits, no thrombosis. At the same time, study the literature on indications, specification, and outcome of portal vein replacement in living donor liver transplantation for children. Replacing the portal vein in children with portal vein stenosis with an autologous donor segment can be performed safely in both the donor and recipient with good initial results.
