  5. 5.  Percutaneous sclerotherapy has emerged as an excellent method of treatment.  Hydroxypolyaethoxydodecan is a sclerosing agent.  It has been sucessfully used in the treatment of AV malformations of 1. GI tract 2. varicose veins 3. Telengiectases, varicose veins
  6. 6.  Sample size = 72  Male= 46, female= 26  Mean age= 15.6  39 lesions – upper limb 29 lesions - lower limb 4 lesions - axial skeleton  Mean follow up 34 months ( 2yrs & 10 months)
  7. 7.  All pts underwent biopsy confirmation  Treatment 3 months after biopsy ( giving time for spontaneous healing)  Preop volume of the lesion was calculated
  8. 8.  < 15 yrs GA, > 15 yrs local  16 gu needle or bone marrow needle used.  Under C arm guidance  1 ml for 1cm3 volume  Lock the needle for 1 min so that no back flow  No more than 10 ml was given
  9. 9. • Follow up 1. 6 weeks 2. 12 weeks 3. 6 months there after
  10. 10. 1. Time at which the pain had resolved. 2. The cortical thickness of the wall of the cyst had started reforming. 3. Lesion had stopped growing in size.  2nd injection was given if any of the above criteria were not met.
  11. 11.  grade I (< 25% of the initial lesion) 66%  grade II (25% to 49%) 30.5%  grade III (50% to 74%) 2.8%  grade IV (75% or more).
  12. 12. 97% success at the end of final follow up
  13. 13.  Recurrence 2 cases  Induration at the site of injection 18 cases,  hypopigmentation 3 cases,  local inflammatory reaction,  episode of dizziness
  14. 14.  hypopigmentation,  necrosis at the site of the injection in the case of extravasation,  pulmonary embolism,  osteomyelitis,  allergic reactions  This series had only hypopigmentation
  15. 15.  skin conditions at the site of injection,  heart disease,  asthma  pregnancy
