[Arteriovenous malformations: a study of 200 cases].

Abstract

The review of these 200 cases pointed out the "pediatric" nature of the problem of arteriovenous malformations in the large majority of the cases and the often misleading presentation of these vascular anomalies, particularly grade I malformations. A false aspect of capillary malformation could raise the risk of inappropriate treatment. This review also confirmed known factors of exacerbation (puberty, pregnancy, trauma) and demonstrated the severity of these vascular anomalies which can progress with loco-regional expansion and invasion without a cellular proliferation component. The analysis of treatments used showed that embolization alone cannot definitively and totally control a superficial arteriovenous malformation and that no one treatment, even combined embolization and large excision, can be a guarantee to provide total cure.
