CASE PRESENTATION Among other causes, arteriovenous malformations (AVMs) can be congenital and associated with Rendu-Osler-Weber disease. It is a conglomerate of anomalous vessels of variable size and number characterized by the lack of an intermediate normal capillary network between the arterial and the venous circuits. Its prevalence is of approximately 1 AVM for every 2600 individuals, and it is a significant cause of morbidity and mortality. The percutaneous closure of AVMs is the standard of care established. However, there is a significant rate of recanalization of AVMs at the long-term follow-up due to the recanalization of the main occluded vessel and the formation of collateral circulation towards the vascular tangle. A few articles already published support sequential embolization to reduce the risk of the latter. This article describes the percutaneous closure of 1 AMV in a pediatric patient using a technique of sequential embolization through rotational angiography, 3D analysis, and roadmapping (technique based on merging the 3D reconstruction acquired through rotational angiography and x-ray images in such a way that reconstruction acts as a «map» or «flight plan» during the procedure). In our opinion this experience is very interesting because, as far as we know, its use has not been described regarding...
