Hiperintensidad en secuencias T2 y tamaño como factores pronósticos de obliteración en malformaciones arteriovenosas tratadas mediante radiocirugía

The nidus size and the development of hyperintensity on T2 MRI after the treatment were the strongest predictive factors of obliteration in our series of AVMs radiosurgically treated. Moreover, given that many AVMs showed complete obliteration between 3-5 years after treatment, we recommend to wait untill 5 years after treatment before considering a new terapeuthic approach in patients showing small residual nidus at control imaging.
