Which of following are features of Klippel- Trenaunay syndrome: 1. Varicose veins 2. Cutaneous bihmark 3. Limb hyperophy 4. Deep veins are often anomalous 5. Saphenous vein striping can be hazardous

Klippel- Trenaunay syndrome: If extensive varicose veins are encountered in young patient, especially if unilateral and an atypical distribution (lateral leg), Klippel- trenaunay syndrome must be considered. The classic triad is varicose vein, limb hyperophy, and a cutaneous bihmark (powine stain or venous malformation). Because the deep veins are often anomalous or absent, saphenous vein striping can be hazardous. Standard treatment for patients with Klippel- Trenaunay syndrome is gradual suppo stockings, limited stab avulsion of symptomatic varices after thorough duplex ultrasound vein mapping, and occasional surgery for correction of limb length discrepancy".
