Total anomalous pulmonary venous return complicating portoenterostomy for biliary atresia.
Cardiovascular anomalies such as absent inferior vena cava and preduodenal portal vein are reported in cases of biliary atresia and make hepatic portoenterostomy a technical challenge. The authors present the case of a severe cardiac anomaly that significantly altered the functional outcome of a Kasai procedure. Baby M., an 8-week-old boy born with total anomalous pulmonary venous return (TAPVR), underwent hepatic portoenterostomy for biliary atresia. Over the next 3 months he remained icteric and febrile, and failed to gain weight. After multiple antibiotic treatments for suspected cholangitis, he underwent reexploration of the portoenterostomy, with no improvement in his overall condition. His prognosis was considered dismal because correction of the cardiac anomaly is associated with a high mortality rate (> 90%). The cardiac surgeon agreed to attempt a cure of the TAPVR, provided liver transplantation is contemplated if the patient survived. Within 48 hours postoperatively, his hepatic function had improved drastically. He became afebrile, had an improved appetite and weight gain, and was finally discharged 203 days after admission. One year later, he is thriving and remains anicteric. The exact reason for this drastic improvement is not well understood, but the right-sided cardiac failure caused by the TAPVR had a significant effect on the functional outcome of the portoenterostomy.
