Aim: The aim of this study was to review the management of children with Wilms' tumour who have intracardiac extension., Patients and Methods: Data were collected from patient notes regarding presentation, operative details, and outcome., Results: From 1984 through 2011, 264 children with Wilms' tumour were treated at our hospital. Nine (3.4%) had cavo-atrial extension of the tumour thrombus. The thrombus extended into the right ventricle in two children and involved the hepatic veins in both, and also two others. Pre-operative chemotherapy was administered in eight children with complete regression of the intra-cardiac tumour thrombus in two cases. One child died preoperatively of septicaemia and respiratory failure after two doses of chemotherapy. Six children with intra-cardiac tumour were operated on under cardiopulmonary bypass (CPB) with deep hypothermia and circulatory arrest (DHCA). The mean ischemic time was 30 min. There was one peri-operative death in a child with hepatic vein involvement and Budd-Chiari syndrome. All others made a good postoperative recovery. All tumours were favourable histology. To date four children are still alive and disease free. Three children have died as a result of pulmonary metastases., Conclusion: Intracardiac extension of Wilms' tumour is rare, and the management is technically challenging. Pre-operative chemotherapy is effective. CPB and DHCA for excision of the cavo-atrial tumour thrombus may be necessary. Distant metastatic disease is common and determines long term prognosis. Hepatic vein extension complicates surgery and remains challenging., (Copyright © 2013 Elsevier Inc. All rights reserved.)

The Budd-Chiari syndrome (BCS), characterized by hepatic venous outflow occlusion, is rare in children. We describe the cases of 3 patients with BCS who presented at different stages of liver dysfunction that required tailored management. A 10-year-old boy who presented with a weeklong history of abdominal discomfort received an early diagnosis. Treatment with thrombolytic therapy and adjunctive percutaneous interventional radiologic management led to a favorable outcome in this patient. A 2-year-old girl referred with a 6-week illness not amenable to thrombolytic therapy was managed with a pericardial patch atriocavoplasty to restore hepatic venous outflow tract patency. The third patient, a 5-year-old girl, presented with established cirrhosis and massive ascites. After we controlled the ascites with an extracorporeal shunt system and nutritional resuscitation, we conducted an orthotopic liver transplantation on this patient. The stage of disease at diagnosis influences the management strategy, and an early diagnosis offers patients the best possible chance of cure without major surgery. However, a later presentation can still be successfully managed by more radical surgical interventions. The aims of this case report were to emphasize the importance of a high index of suspicion in the diagnosis of pediatric BCS and to highlight the importance of early referral to a specialized pediatric liver unit with the necessary facilities to deal with the medical and surgical aspects of management.
