Congenital vascular malformations are rare anomalies resulting from an inborn error during the vascular network development. They are rare inborn lesions characterized by deficient smooth muscle layer leading to vascular dilatation with impaired functions. Congenital vascular malformations may occur in a spectrum of clinical presentation ranging from ectasia or varicosity to a more complicated lesion that can affect any organ system. Although they are present at birth, they grow proportionally during childhood and adolescence, becoming clinically evident later in life. The symptoms differ depending on location, extension, and size. They may bleed and result in disfigurement, functional impairment, and pain. In this case report, successful surgical treatment of a child with a congenital vascular malformation in his right leg was presented. This case and its detailed intraoperative and radiological images are original as there is no similar example in the available literature.
