Arterial-venous fistulas following pediatric liver transplant case studies.
AV fistula is a rare but serious complication following pediatric liver transplant and may lead to graft loss. Our aim was to describe two pediatric centers' experience with the diagnosis, treatment and outcomes of children who presented with AV fistulas post-liver transplantation We report five cases of late arterio-portal fistula following liver transplantation. Four children were successfully treated with coil embolization. All of the children in this series had liver biopsies within 2-6 months of their AV fistula diagnosis. All biopsies were performed using a Bard Monopty 18 gauge needle with no ultrasound guidance and only one pass per biopsy. Two children also had PTC 4-8 months prior to their diagnosis of AV fistula. Three of the five children in this series had GI bleeds requiring banding or sclerotherapy. The other two had varices found on CT scan. All five cases in this series had ascites on their initial presentation. Four out of the five children had a history of non-compliance and the other child had a history of malabsorption and chronic diarrhea.
