Ultrasound represents the first imaging exam for patients with vascular malformations. In some cases, additional and sometimes functional imaging will be necessary to confirm the diagnosis or to highlight a vascular network of drainage. Doppler ultrasound could be not enough and a certain number of complementary examinations are then required. Contrast-enhanced ultrasound (CEUS) is used in current practice in the vascular field and in particular the monitoring of aortic stents.</p><p><strong>Method: </strong>We present here the interest of using CEUS in VascM through a review of the literature.
