RESUMEN:
Objetivo: Presentar la experiencia de manejo de miomatosis con embolización arterial selectiva. Material y métodos: Estudio observacional, transversal, descriptivo y prospectivo durante el periodo enero 2015-diciembre 2019, en pacientes sometidos a embolización arterial selectiva como tratamiento de miomatosis. Se registraron características clínicas y desenlaces de interés para su análisis estadístico (edad, síntomas, tipo de miomas, características imagenológicas, cambios en el tamaño y severidad de síntomas a seis meses). Resultados: Las manifestaciones clínicas más frecuentes fueron hiperpolimenorrea (40.9%), anemia (13.6%), infertilidad (9.1%) y dispareunia (9.1%). El 68.2% de los miomas fueron FIGO 2 (submucosos > 50% intramurales), 22.7% FIGO 1 (submucosos < 50% intramural) y 9.1% FIGO 5 (subserosos > 50% intramural). Por resonancia magnética en ponderación T2, el 4.5% fueron clasificados como isointensos, el 9.1% hiperintensos, el 68.2% heterogéneos mayormente hipointensos (degeneración hialina) y el 18.2% heterogéneos mayormente hiperintensos (degeneración quística). A los seis meses, en dos pacientes se redujo el tamaño en un 95%, en tres un 75%, en 16 un 50% y en una un 25%. La tasa de procedimientos exitosos fue del 95.5% y la intensidad de la sintomatología disminuyó en todas las pacientes más del 90%. Conclusiones: La miomatosis fue exitosamente tratada con embolización arterial selectiva, se redujo el tamaño de los miomas y la sintomatología asociada.

ABSTRACT:
Objective: To present the experience of managing myomatosis with selective arterial embolization. Material and methods: Observational, cross-sectional, descriptive and prospective study during the period January 2015- December 2019, in patients undergoing selective arterial embolization as a treatment for myomatosis. Clinical characteristics and outcomes of interest were recorded for statistical analysis (age, symptoms, type of fibroids, imaging characteristics, changes in size and severity of symptoms at 6 months). Results: The most frequent clinical manifestations were hyperpolymenorrhea (40.9%), anemia (13.6%), infertility (9.1%) and dyspareunia (9.1%). 68.2% of the fibroids were FIGO 2 (submucosal > 50% intramural), 22.7% FIGO 1 (submucosal < 50% intramural) and 9.1% FIGO 5 (subserous > 50% intramural). By T2-weighted MRI, 4.5% were classified as isointense, 9.1% hyperintense, 68.2% heterogeneous, mostly hypointense (hyaline degeneration), and 18.2% heterogeneous mostly hyperintense (cystic degeneration). At 6 months, in 2 patients the size was reduced by 95%, 75% in three, 50% in 16 and 25%. The rate of successful procedures was 95.5% and the intensity of symptoms decreased in all patients more than 90%. Conclusions: The myomatosis was successfully treated with selective arterial embolization, the size of the fibroids and the associated symptoms were reduced.
