Conservative treatment of suprahepatic pseudoaneurysm in a pediatric patient. / Manejo conservador de un pseudoaneurisma suprahepático en un paciente pediátrico.

INTRODUCTION: Suprahepatic and inferior vena cava (IVC) pseudoaneurysms are rare in children. Most cases in adults are treated surgically due to the high risk of rupture. CASE REPORT: Seven-year-old girl referred for a thoracic-abdominal trauma of unknown origin. Hemodynamically stable, with a hemoglobin level of 9.1 g/dl. An emergency CT scan was performed, showing a pseudoaneurysm at the confluence of the IVC with the middle and left suprahepatic veins, with active bleeding contained by the hepatic capsule. Given the hemodynamic stability and surgical risk, conservative treatment was decided upon. CT-scan at 24 hours showed cessation of bleeding. A control CT-scan was performed one month, three months, one year, and one and a half years later, showing the lesion had disappeared. DISCUSSION: Conservative treatment of suprahepatic vein pseudoaneurysm/ICV is feasible in the case of hemodynamic stability provided that strict clinical and radiological surveillance is maintained.

INTRODUCCION: Los pseudoaneurismas suprahepáticos y de la vena cava inferior (VCI) son excepcionales en niños. La mayoría de casos en adultos se manejan quirúrgicamente debido al alto riesgo de rotura. CASO CLINICO: Niña de siete años remitida por traumatismo tóraco-abdominal no presenciado. Hemodinámicamente estable, con hemoglobina de 9,1 g/dL. Se realiza un TC urgente, objetivándose un pseudoaneurisma en la confluencia de la VCI con las suprahepáticas media e izquierda, con sangrado activo contenido por la cápsula hepática. Dada la estabilidad hemodinámica y el riesgo quirúrgico, se optó por un manejo conservador. En el TC a las veinticuatro horas se observó cese del sangrado. Se realizó un TC de control al mes, tres meses, un año y año y medio, con desaparición de la lesión. COMENTARIOS: El manejo conservador del pseudoaneurisma de las venas suprahepáticas/VCI es factible en caso de estabilidad hemodinámica siempre que se mantenga una vigilancia clínica y radiológica estrechas.

T-tube Systematic Use in the Biliary Anastomosis: Comparison of Two Consecutive Series of Liver Transplantation.

OBJECTIVES: The authors sought to check the frequency of biliary complications with the use of a T-tube. In 2012, throughout the year, it was carried out systematically in all liver transplantations regardless of the characteristics of the bile duct. Despite the long experience, biliary complications remain a common cause of postoperative morbidity and mortality. MATERIAL AND METHODS: In this study we compared complications in 23 consecutive transplantation cases using T-tube biliary anastomosis during the year 2012 with 23 consecutive transplantation cases without T-tube during the year 2013. We evaluated postoperative complications and long-term outcomes (for 2 years to 3 years). RESULTS: Of the 23 patients with anastomosis with a T-tube, 2 patients (8.69%) had biliary stricture that required prosthesis by endoscopic retrograde cholangiopancreatography, 1 of them (4.34%) was operated by incorrect placement of the T-tube, and in 4 patients (17.39%) bile leakage (endoscopic retrograde cholangiopancreatography prostheses in 3 cases and hepaticojejunostomy in 1). During follow-up at 3 years, only 2 patients had minimal bile duct dilatation without clinical relevance. In the patients who underwent transplantation without a T-tube, 18 (78.26%) had no complications, 3 (13.04%) showed stenosis (prosthesis placement), and 2 (8.69%) had bile leakage (hepaticojejunostomy and prosthesis). During follow-up at 2 years to 3 years, no patient had biliary dilatation or alteration of cholestatic parameters. In the comparative study of both groups we found no statistically significant differences. CONCLUSIONS: We have not seen an improvement in complications with the use of T-tube (69.56% vs. 78.23%) that encourage us to work systematically, although the small number of cases does not allow statistically significant conclusions.

Collateral Development in Thrombosis of the Hepatic Artery After Transplantation.

OBJECTIVES: The authors sought to identify strictures or hepatic artery obstruction with posterior collateral transformation in our series of liver transplantation, treatment, and evolution. The thrombosis or severe hepatic artery stenosis sometimes presents a compensation mechanism, the collateral transformation of the artery. MATERIAL AND METHODS: From April 2002 to December 2011 we collected 18 cases of collateral transformation. We analyzed data regarding the transplantation, diagnosis, treatment, clinical evolution, liver function, and Doppler-ultrasound. RESULTS: The main indication was alcoholic cirrhosis, followed by hepatocellular carcinoma - hepatitis C virus. The mean cold ischemia time was 292.2 minutes mean hot ischemia was 48.8. The anastomosis was performed on the gastroduodenal-splenic patch donor in 14 cases, the celiac trunk in 2 cases, and on grafts to the aorta in another 2. Doppler ultrasound showed 8 cases without complications, 8 with low flows, and 2 cases with alterations of the right hepatic artery. Computed tomographic (CT) angiography was performed in patients with impaired eco-Doppler and found 4 obstructions, 2 cases with kinking, 1 stenosis, and 3 normal cases. Three patients with low flows were re-operated and another re-transplanted. After diagnosis of collateral transformation, all were treated with antiplatelet agents. Two cases of angioplasty were associated. The collaterals were diagnosed 1 month to 44.8 months after transplantation. Five patients died. In the latest data, 10 patients do not have analytical alteration. The Doppler ultrasound shows 7 cases being normal and 6 with flow but low resistances. CONCLUSIONS: In our series, all patients with collateral transformation, except one who was transplanted, maintain good liver function with permeable vessels.
