Abstract
Objectives

To evaluate the safety and patency of self-expanding stents to treat hepatic venous outflow obstruction after orthotopic liver transplantation. To evaluate differences in the response between patients with early obstruction and patients with late obstruction.

Material and methods

This is a retrospective analysis of 16 patients with hepatic venous outflow obstruction after liver transplantation treated with stents (1996–2011). Follow-up included venography/manometry, ultrasonography, CT, and laboratory tests. We did a descriptive statistical analysis of the survival of patients and stents, technical and clinical success of the procedure, recurrence of obstruction, and complications of the procedure. We also did an inferential statistical analysis of the differences between patients with early and late obstruction.

Results

The mean follow-up period was 3.34 years (21–5331 days). The technical success rate was 93.7%, and the clinical success rate was 81.2%. The rate of complications was 25%. The survival rates were 87.5% for patients and 92.5% for stents. The rate of recurrence was 12.5%. The rate of primary patency was 0.96 (95% CI 0.91–1) at 3 months, 0.96 (95% CI 0.91–1) at 6 months, 0.87 (95% CI 0.73–1) at 12 months, and 0.87 (95% CI 0.73–1) at 60 months. There were no significant differences between patients with early and late obstruction, although there was a trend toward higher rates of primary patency in patients with early obstruction (P=0.091).

Conclusions

Treating hepatic venous outflow obstruction after orthotopic transplantation with self-expanding stents is effective, durable, and effective. There are no significant differences between patients with early obstruction and those with late obstruction.

Resumen
Objetivos

Evaluar la seguridad y permeabilidad del tratamiento de la obstrucción del drenaje venoso hepático tras trasplante ortotópico con endoprótesis autoexpandibles. Valorar las diferencias en la respuesta en pacientes con obstrucción precoz y tardía.

Material y métodos

Análisis retrospectivo de 16 pacientes trasplantados con obstrucción del drenaje venoso hepático tratados con endoprótesis (1996–2011). El seguimiento se realizó mediante venografía/manometría, ecografía, TC y pruebas de laboratorio. Se realizó análisis estadístico descriptivo de supervivencia de pacientes e injertos, éxito técnico y clínico, recurrencia y complicaciones del total de la muestra, así como inferencial para comparar las diferencias entre pacientes con obstrucción precoz y tardía.

Resultados

La media de seguimiento fue de 3,34 años (21–5.331 días). La tasa de éxito técnico fue del 93,7%, y la de éxito clínico, del 81,2%. La tasa de complicaciones fue del 25%. La tasa de supervivencia para pacientes fue de 87,5%, y para injertos, de 92,5%. La tasa de recurrencia fue del 12,5%. La tasa de permeabilidad primaria a los 3, 6, 12 y 60 meses fue de 0,96 (IC 95% 0,91–1), 0,96 (IC 95% 0,91–1), 0,87 (IC 95% 0,73–1) y 0,87 (IC 95% 0,73–1), respectivamente. No hubo diferencias significativas entre los pacientes con obstrucción precoz o tardía, aunque las tasas de permeabilidad primaria mostraron tendencia a ser significativamente superiores en el grupo precoz (p=0,091).

Conclusiones

El tratamiento con endoprótesis autoexpandibles en obstrucciones del drenaje venoso hepático tras trasplante ortotópico es efectivo, duradero y seguro. No hay diferencias significativas entre pacientes con obstrucción precoz y tardía.
