Abstract
Objective

To retrospectively analyze the safety and efficacy of transjugular intrahepatic portosystemic shunting (TIPS) using covered stents in children.

Material and methods

We present 6 children (mean age, 10.6 years; mean weight, 33.5kg) who underwent TIPS with 8mm diameter Viatorr® covered stents for acute (n=4) or recurrent (n=2) upper digestive bleeding that could not be controlled by endoscopic measures. Five of the children had cirrhosis and the other had portal vein thrombosis with cavernous transformation. We analyzed the relapse of upper digestive bleeding, the complications that appeared, and the patency of the TIPS shunt on sequential Doppler ultrasonography or until transplantation.

Results

A single stent was implanted in a single session in each child; none of the children died. The mean transhepatic gradient decreased from 16mmHg (range: 12–21mmHg) before the procedure to 9mmHg (range: 1–15mmHg) after TIPS.

One patient developed mild encephalopathy, and the girl who had portal vein thrombosis with cavernous transformation developed an acute occlusion of the TIPS that resolved after the implantation of a coaxial stent.

Three children received transplants (7, 9, and 10 months after the procedure, respectively), and the patency of the TIPS was confirmed at transplantation. In the three remaining children, patency was confirmed with Doppler ultrasonography 1, 3, and 5 months after implantation. None of the children had new episodes of upper digestive bleeding during follow-up after implantation (mean: 8.1 months).

Conclusion

Our results indicate that TIPS with 8mm diameter Viatorr® covered stents can be safe and efficacious for the treatment of upper digestive bleeding due to gastroesophageal varices in cirrhotic children; our findings need to be corroborated in larger series.

Resumen
Objetivo

Analizar retrospectivamente la seguridad y eficacia de derivación portosistémica intrahepática por vía transyugular (TIPS) recubierta en niños.

Material y métodos

Presentamos 6 niños con una edad media de 10,6 años y un peso medio de 33,5kg, a quienes se implantaron endoprótesis recubiertas tipo Viatorr® de 8mm de diámetro por hemorragia digestiva alta (HDA) aguda (n=4) o recurrente (n=2) no controlable por medidas endoscópicas. Cinco niños eran cirróticos y otro un trasplantado hepático con trombosis y cavernomatosis portal. Se valoraron la recidiva de la HDA, las complicaciones y la permeabilidad con ecografías-Doppler secuenciales o hasta el trasplante.

Resultados

En todos los niños se implantó una sola endoprótesis en una única sesión, sin mortalidad asociada. El gradiente transhepático medio inicial fue de 16mmHg (12-21mmHg) y disminuyó tras la implantación del TIPS a 9mmHg (1-15mmHg).

Un paciente presentó encefalopatía leve y la niña con trombosis y cavernomatosis portal presentó una oclusión aguda del TIPS, que se resolvió con la implantación de una endoprótesis coaxial.

Tres niños fueron sometidos a trasplante a los 7,9 y 10 meses, constatándose la permeabilidad del TIPS. En los 3 restantes se comprobó la permeabilidad con ecografía-Doppler a los 1,3 y 5 meses. Ninguno presentó una nueva HDA durante un seguimiento medio de 8,1 meses.

Conclusión

Nuestros resultados indican que la seguridad y permeabilidad de las endoprótesis recubiertas tipo Viatorr® para el tratamiento de la HDA por varices gastroesofágicas en niños cirróticos pueden ser buenas, hecho que deberá ser corroborado con series mayores en un futuro.
