RESUMO
This study aims at quantification of ovarian dose in uterine artery embolisation to study the level of optimisation of this dose. Individual anatomical data and all relevant exposure parameters of individual beam projections were recorded in 52 patients who underwent uterine artery embolisation in two angiography units. The recorded information was used to calculate the individual ovarian doses by Monte Carlo simulation. The mean dose-area product was 196 Gy cm(2). The corresponding mean ovarian dose was 149 mGy. The performance of the two angiography units was analysed starting from these data. Dose-area product and ovarian doses obtained in this study were compared with data from other uterine artery embolisation patient dose studies. It was concluded that although the mean dose-area product and ovarian dose are acceptable, it is possible to optimise the procedure by improving the performance of the units.

La preeclampsia continúa siendo una de las principales causas de morbilidad y mortalidad materna y perinatal. A pesar de su repercusión, hasta ahora no ha habido métodos adecuados para detectarla de forma temprana y prevenir complicaciones. Las estrategias de selección basadas en la presencia de factores de riesgo maternos no resultan eficientes. El empleo del Doppler de arterias uterinas no se ha conseguido imponer en la práctica habitual, pero en combinación con los nuevos marcadores angiogénicos sFlt-1 y PlGF se convierte en una herramienta con gran potencial para la predicción y el diagnóstico temprano de la preeclampsia. En este artículo se discutirá la oportunidad de trasladar a la clínica diaria el estudio Doppler de arterias uterinas y los marcadores angiogénicos sFlt-1 y PlGF en función de los datos conocidos a través los estudios realizados recientemente(AU)
Pre-eclampsia remains a principal cause of maternal and perinatal morbidity and mortality. Despite its repercussions, so far there have been no methods for early diagnosis and prevention of complications. Selection strategies based on the presence of maternal risk factors are not efficient. The use of uterine artery Doppler has not been accepted in routine practice, but in combination with new angiogenic markers sFlt-1 and PlGF it becomes a very powerful tool for the prediction and early diagnosis of pre-eclampsia. This article will discuss the challenge of transferring the study of uterine artery Doppler and angiogenic markers sFlt-1 and PlGF to daily clinical practice in the light of the available data from recent studies(AU)
