Clean FRCS notes with inline figures
Klippel–Trénaunay syndrome
•Rare
•Capillary malformation → Port wine stain
•Venous / lymphatic malformation
•Soft tissue hypertrophy
•Other conditions with AVM
•Parkes Webers syndrome: capillary, lymphatic and venous malformations with AV fistulas
•Proteus syndrome: capillary and venous malformations, macrodactylyl, hemihypertrophy, lipomas, pigmented nevi, scoliosis
•Maffucci’s syndrome: lymphatic and venous malformation and multiple enchondromas
Treatment
•Resection may be dangerous
•Consider embolization therapy
•Ligation of feeding vessels of no help
•High flow AV malformations are difficult to treat, and staged partial excision are mostly palliative
•Proximal ligation only increases collateralization, and embolization carries high risk of digital ischemia
•YAG laser used in direct contact with tissue for incision and thermal coagulation, has allowed subtotal excision of complicated hemangiomas of the hand previously thought to be untreatable
•Laser will not stop bleeding from blood vessels with lumen diameters greater than 1mm
