Abstract

Dysplasia of the great veins (DMV), or Klippel–Trenaunay syndrome (KTS), is a rare disease, the incidence of which varies, according to different authors, from 1 to 5 per 100,000 people, with a slight predominance of male patients. The clinical picture of the syndrome is characterized by a triad of symptoms: vascular spots, varicose atypical veins, hypertrophy of soft tissues and bones with an increase in the volume and length of the affected limb. It should be emphasized that the severity of these symptoms depends primarily on the type (embryonic or fetal) and severity of the disease. Recent studies have shown that the pathogenesis of TSC can be caused by mutations in the PIK3CA gene or by thrombosis of the main veins of the extremities suffered in the prenatal period. To diagnose the malformation, ultrasound — Dopplerography, magnetic resonance imaging and multislice computed tomography with contrast, ascending phlebography are used. Vasocontrast methods allow to identify various variants of surgical anatomy of the veins of the affected extremities. To assess the anatomy of the deep veins, we used ultrasound diagnostics and ascending contrast.
