ABSTRACT
PURPOSE: To evaluate feasibility, safety, and results of endovenous mechanochemical ablation (MOCA) for treatment of persistent embryonic and dysplastic veins in pediatric patients with Klippel-Trénaunay syndrome (KTS). MATERIALS AND METHODS: Thirteen MOCA procedures were performed in 11 patients (age range, 4-16 years) with KTS and symptomatic persistent embryonic or dysplastic veins during a 24-month period. All patients were evaluated with color Doppler (CD) ultrasound (US), contrast-enhanced MR imaging, and venography to assess the anatomy of the target vessels and patency of the deep venous system. All procedures were performed under general anesthesia with a ClariVein catheter and liquid sodium tetradecyl sulfate as the sclerosing agent. US and fluoroscopic guidance were used in all cases. Technical success rate, primary occlusion rate, adverse effects, and recanalization rates were evaluated. Clinical and radiological (CD US) controls were performed 1 day, 7 days, 1 month, and 6 months after the procedure and once a year thereafter, with a mean follow-up of 16 months (range, 6-25 months). RESULTS: Technical success and primary occlusion were achieved in all patients with no adverse events. During the follow-up period, CD US demonstrated partial recanalization and symptom recurrence in 2 patients (18%), 14 and 18 months after the initial procedure. These 2 patients had a second ablation procedure with no recanalization or symptom recurrence during the subsequent follow-up period. CONCLUSIONS: MOCA is feasible and appears to be a safe and effective technique for treatment of varicose veins in pediatric patients with KTS.

El 25 % de la población mundial se encuentra infectada por Ascaris lumbricoides. La ascaridiosis hepatobiliar ocurre en zonas con alta endemicidad y gran carga parasitaria, y genera desde intensa inflamación hasta fibrosis. Se presenta a un paciente de 2 años, que consultó por distensión abdominal y tos de 1 mes de evolución asociada a fiebre en las últimas 72 h. Se realizó una ecografía abdominal que evidenció áscaris en la vía biliar, en el estómago y en el intestino delgado, y una radiografía de tórax con infiltrado inflamatorio intersticial, asociado a hiperleucocitosis con hipereosinofilia y gamma-glutamiltranspeptidasa elevada. Se administró un tratamiento antibiótico, antihelmíntico, sin lograr la eliminación de los parásitos de la vía biliar, por lo que se requirió su extracción mediante colangiografía percutánea
Twenty five percent of the world population is affected by Ascaris lumbricoides. Hepatobiliary ascariasis occurs in areas with high endemicity and great amount of parasitic load, generating intense inflammation to fibrosis. We report a two-year-old patient that consults about abdominal distension and cough of one month of evolution associated with 72 hours of fever. Abdominal ultrasound is performed, which shows bile duct, stomach, small intestine with ascaris and chest x-ray with interstitial inflammatory infiltrate, associated with hyperleukocytosis with hypereosinophilia and elevated gamma-glutamyl transpeptidase. Antibiotic, anthelminthic treatment is administered, without achieving the elimination of the bile duct parasites, requiring their removal by percutaneous cholangiography.

The aim of this study is to correlate the US, laboratory, and cholangiography findings in pediatric liver transplant patients with biliary complications, trying to identify reliable decision-making tools for the management of these complications. Retrospective review was carried out of US results in 39 consecutive patients, from 2011 to 2013, with biliary complications after LT, documented by PTC. According to US biliary dilation, patients were classified as: mild, moderate, and severe, and according to laboratory findings as: normal or abnormal serum bilirubin and level of serum GGT. Data were correlated with PTC findings, divided in three groups: mild, moderate, and severe/occlusive BDS. There was no statistically significant correlation between the US findings and the laboratory findings and between US findings with PTC. There was a statistically significant correlation between GGT and cholangiography. In our series, abnormal US could not predict the severity of BDS on PTC. Bilirubin results were not able to predict the US findings either. GGT results demonstrated a statistically significant correlation with the severity of BDS found on PTC. These findings emphasize the role of GGT in the evaluation and decision of biliary interventions in pediatric liver transplant recipients.
