and therefore&#44; to the blood pressure in such vessels&#46; High-flow VM are the arteriovenous malformations and the arteriovenous fistula&#46; Also&#44; those combined VM that show an arteriovenous component usually have areas of high-flow&#46; Distinguishing low-flow from high-flow VM can be done before surgery by using ultrasound or dynamic magnetic resonance imaging&#46;<a class="elsevierStyleCrossRef" href="#bib0300"><span class="elsevierStyleSup">18</span></a> The clinical and therapeutic approach to a VM highly depends on the evidence of high-flow areas or not&#46;

the classification of vascular anomalies proposed by the International Society for the Study of Vascular Anomalies &#40;ISSVA&#41; made a crucial contribution&#58; the division into two main groups of vascular anomalies&#58; vascular tumors and vascular malformations &#40;VM&#41;&#46;<a class="elsevierStyleCrossRef" href="#bib0215"><span class="elsevierStyleSup">1</span></a> At that time&#44; differences between these two groups seemed solid and clear&#58; while tumors were considered proliferating acquired growths made of newly formed vessels&#44; VM were congenital anomalies made of non-proliferating dysmorphic vessels&#46; This new classification allowed for the successful clinical and therapeutic approach of many vascular anomalies&#46; The principles of ISSVA classification have been recently adopted by the WHO in the recently launched classification of Pediatric Tumors&#46;<a class="elsevierStyleCrossRef" href="#bib0220"><span class="elsevierStyleSup">2</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">As time passed&#44;

and therefore&#44; to the blood pressure in such vessels&#46; High-flow VM are the arteriovenous malformations and the arteriovenous fistula&#46; Also&#44; those combined VM that show an arteriovenous component usually have areas of high-flow&#46; Distinguishing low-flow from high-flow VM can be done before surgery by using ultrasound or dynamic magnetic resonance imaging&#46;<a class="elsevierStyleCrossRef" href="#bib0300"><span class="elsevierStyleSup">18</span></a> The clinical and therapeutic approach to a VM highly depends on the evidence of high-flow areas or not&#46; When the latter carries a high risk for hemorrhage&#44; invasive therapy &#40;endovascular&#44; surgical&#44; and&#47;or radiation therapy&#41; versus medical management alone&#44; is indicated&#46; Otherwise&#44;
