Embolization of bronchial arteries and nonbronchial systemic arteries with n-butyl-cyanoacrylate in patients with hemoptysis: A retrospective single-center study.

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.

Embolización de arterias bronquiales y arterias sistémicas no bronquiales con n-butil-cianoacrilato en pacientes con hemoptisis: un estudio monocéntrico y retrospectivo / Embolization of bronchial arteries and nonbronchial systemic arteries with n-butyl-cyanoacrylate in patients with hemoptysis: a retrospective single-center study

Objetivos Evaluar la seguridad y la eficacia de la embolización de arterias bronquiales y arterias sistémicas no bronquiales con n-butil-cianoacrilato 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 (AU)

Cateterización percutánea de la arteria glútea superior para el tratamientode un aneurisma de arteria ilíaca interna / Posterior percutaneous superior gluteal artery catheterization for internal iliac artery aneurysm treatment

Introducción: actualmente los aneurismas de la arteria ilíaca interna se tratan en su mayoría por vía endovascular. En pacientes con intervenciones previas puede ser especialmente difícil tratarlos dada la ausencia de accesos arteriales “clásicos”. Caso clínico: varón de 80 años con crecimiento del saco aneurismático de la arteria ilíaca interna derecha en el que era imposible un acceso percutáneo por vía anterógrada ilíaca y por vía retrógrada femoral por intervenciones previas al que se le realizó un tratamiento mediante punción percutánea de la arteria glútea superior mediante embolización transcatéter con coils. Discusión: en ausencia de accesos clásicos para tratamiento endovascular de un aneurisma de ilíaca interna, la punción transglútea es una técnica sencilla y reproducible que ofrece una alternativa en estos escenarios.(AU)

Introduction: currently, internal iliac artery aneurysms are generally treated with endovascular techniques, in patients with previous interventions it can be particularly challenging to treat these lesions due to lack of a patent “classical” access site. Case report: we report a case of an 80-year-old man with a growing right internal iliac aneurysm, in which a percutaneous antegrade access through the iliac artery or a retrograde access to the femoral artery were impossible due to previous interventions, that was managed with trans catheter coil embolization with a percutaneous puncture to the superior gluteal artery. Discussion: when classical endovascular approaches to the intern iliac artery are absent, the transgluteal puncture is a simple and replicable technique, offering an alternative in challenging scenarios.(AU)
