Design outcomes

Primary

MeasureTime frame
Describe the genetic and epigenetic changes (DNA methilation, mRNA expression, DNA mutation) of the ressection products of arteriovenous malformations of patients in this cohort

Secondary

MeasureTime frame
Describe epidemiological and clinical data of patients treated by the institution's vascular neurosurgery group;Compare outcomes, both clinical and radiological, with other similar studies in the literature;Describe in detail the findings in DNA methylation and histone acetylation tests in collected pathological specimens;Describe in detail the DNA mutations found by the exome technique and compare with the prevalence of somatic mutations in the general population;Follow-up patients for one year after resection to describe late findings of complications related to the surgical procedure (i.e., infection, hydrocephalus, recurrence of injury)
