Anomalies veineuses congénitales des membres inférieurs

Abstract

Lower limbs venous anomalies include a group of morphological or functional deteriorations of superficial and/or deep veins, originating from a break in their morphogenesis, at a more or less advanced stage. They belong to the vast register of venous malformations. These sporadic and rare lesions, which may be due to a genetic deterioration with variable expressions, are sometimes latent and fortuitously encountered, or symptomatic and therefore lead to a panel of sever chronic venous insufficiency. They can be isolated or part of a range of complex abnormalities. Their assessment greatly benefited from the use of ultrasound methods and of magnetic resonance imaging, some methods, which enable to distinguish the shapes when therapeutic abstention is recommended and those when a medical treatment, interventional radiology, or surgery is required.
