A 9-month-old girl was brought by her parents because of swelling of the right leg since birth. On examination there was hemi-hypertrophy, venous varicosities and pinkish discoloration.

Plain radiographs showed marked soft tissue enlargement and mild bone enlargement.

Colour Doppler showed absent deep venous system and few varicose venous channels.

Angiography of right lower extremity showed increased little tortuous arterial branches and absent deep venous system

What is the most likely diagnosis?


Klippel-Trénaunay Syndrome

Klippel-Trénaunay Syndrome  is a rare congenital malformation characterised by the triad of capillary malformations, atypical varicosities or venous malformations, and bony or soft tissue hypertrophy usually affecting one extremity.The most frequent clinical aspect of Klippel-Trenaunay Syndrome is a dermal capillary stain associated with dilated marginal vein of Servelle often identified in the subcutaneous fat of the lateral calf and thigh. It should be distinguished from Parkes-Weber syndrome by absence of underlying arteriovenous malformation.Prominent superficial varicose veins are present in majority of the patients.Extremity pain, spontaneous haemorrhages, venous insufficiency or thrombophlebitis are commonly encountered. Treatment is usually conservative and includes application of graded compressive stockings or pneumatic compression devices. Percutaneous sclerosis of varicosities and surgical treatment by epiphysiodesis to control leg length discrepancy, excision of hypertrophied soft tissue or less commonly reconstructive surgery of deep venous obstruction has been reported in some patients.
