Abstract
Objectives

To evaluate the safety and efficacy of the embolization of bronchial arteries and nonbronchial systemic arteries with n-butyl-cyanoacrylate (NBCA) in patients with hemoptysis.

Methods

We analyzed a total of 55 consecutive patients with hemoptysis (14 mild, 31 moderate, and 10 massive) treated with the embolization of bronchial arteries and nonbronchial systemic arteries with n-butyl-cyanoacrylate between November 2013 and January 2020. The main variables analyzed were the rates of technical success, of clinical success, of recurrence, and of complications. Statistics included a descriptive analysis and Kaplan-Meier survival curves.

Results

Embolization was a technical success in 55 (100%) and a clinical success in 54 (98.2%). During follow-up (mean, 23.8 months; interquartile range, 9.7–38.2 months), hemoptysis recurred in 5 (9.3%) patients. The nonrecurrence rate was 91.9% one year after the initial procedure and 88.7% two years and four years after the initial procedure. Minor complications related with the procedure occurred in 6 (10.9%); no major complications occurred.

Conclusions

The embolization of bronchial arteries and nonbronchial systemic arteries with n-butyl-cyanoacrylate is safe and efficacious for controlling hemoptysis, resulting in low recurrence rates.

Resumen
Objetivos

Evaluar la seguridad y la eficacia de la embolización de arterias bronquiales (AB) y arterias sistémicas no bronquiales (ASNB) con n-butil-cianoacrilato (NBCA) en pacientes con hemoptisis.

Métodos

Se han analizado un total de 55 pacientes consecutivos con hemoptisis (14 leves, 31 moderadas y 10 masivas) tratados mediante embolización de arterias bronquiales y arterias sistémicas no bronquiales con n-butil-cianoacrilato entre noviembre de 2013 y enero de 2020. Las variables principales estudiadas son tasa de éxito técnico, tasa de éxito clínico, tasas de recurrencia y complicaciones. Se ha realizado un análisis estadístico descriptivo y un análisis de supervivencia mediante el método de Kaplan-Meier.

Resultados

En 55 (100%) pacientes se ha realizado la embolización con éxito técnico y en 54 (98,2%), con éxito clínico. Durante el seguimiento (media, 23,8 meses; rango intercuartílico, 9,7–38,2) ha recurrido en 5 de los 54 (9,3%) pacientes. La tasa de no recurrencia al año ha sido del 91,9%, y a los 2 y 4 años, del 88,7% después del procedimiento inicial. Ha habido 6 (10,9%) complicaciones menores relacionadas con el procedimiento y ninguna mayor.

Conclusiones

La embolización de arterias bronquiales y arterias sistémicas no bronquiales con n-butil-cianoacrilato es segura y eficaz para controlar la hemoptisis con tasas de recurrencia bajas.
