[Budd-Chiari syndrome in children and adolescents: therapeutic radiological intervention].

Abstract

OBJECTIVE Due to its minimal-invasive approach, endovascular procedure had replaced surgery in treating Budd-Chiari syndrome (BCS). The interventional therapy was a safe and effective treatment in adults with BCS and the cure rate was high. However Budd-Chiari syndrome in children and adolescents is rare. Published literature on interventional procedure for Budd-Chiari syndrome in children and adolescents is scarce. The aim of the study was to present results of percutaneous transluminal angioplasty (PTA) and stents placement in children and adolescents with BCS and to evaluate the efficacy and safety in these patients of this approach. METHOD Twenty-five patients [16 boys and 9 girls; average age of (14.5 ± 3.4) years old; age ranged from 5 to 17 years] with Budd-Chiari syndrome who were hospitalized from December 1990 to August 2012 were presented. All of them were diagnosed by color Doppler ultrasound scan while 12 of them had magnetic resonance venography (MRV) scan. All of the patients had undergone angiographic examination. Four cases with membranous obstruction of the inferior vena cava (IVC) were treated with PTA. One case with segmental block of IVC was treated with PTA and stent placement. Five cases with membranous obstruction of IVC and hepatic vein (/and accessory hepatic vein) were treated with PTA. Among 8 cases with membranous obstruction of hepatic veins, 6 cases were treated with PTA and the others with PTA and stent placement. Among 4 cases with blocks of 3 hepatic veins (HVs), one was treated with PTA, one with PTA plus catheter thrombolysis plus PTA, one with PTA and stent placement and the other one was unsuccessful. Three cases with obstruction of HV and accessory HV (AHV) were treated with PTA. Totally, 24 patients were treated with interventional approach and followed up. RESULT The procedure was successful in 24 patients. The involved veins (hepatic veins or IVC) were patented after interventional procedure. The pressure of hepatic vein was (42.1 ± 4.2) cm H2O (37-50 cm H2O) (1 cm H2O = 0.098 kPa) before the interventional therapy, while it was (17.3 ± 3.3) cm H2O (14-26 cm H2O) after it. The pressure of IVC was (30.6 ± 2.9) cm H2O (26-36 cm H2O) before the interventional therapy, while it was (18.8 ± 4.2) cm H2O (15-26 cm H2O) after it. The symptoms and signs vanished instantly after interventional procedure. There were no procedure-related complications. The rate of overall initial cure was 96%. The patients were followed up for a mean of 25.8 months (range 6 months to 8 years). Seven cases developed restenosis after first procedure. Five of them were treated with PTA, one with PTA plus catheter thrombolysis plus PTA, one with PTA and stent placement. All of the involved veins were patented again. Clinical symptoms were relieved. There were no procedure-related complications as well. CONCLUSION The interventional procedure in children and adolescents with BCS is the same as in adults. Radiological therapeutic intervention is efficacious and safe in children and adolescents with BCS.
