Outcome Measures

Primary Outcomes (2)

  • Evidence of decreased bone density in patients with vascular malformations, confirmed by DEXA scans

    One year

  • Evidence of decreased bone density in patients with vascular malformations, confirmed by serum specific bone markers

    Bone markers : Alkaline phosphatase; albumin; PTH; 1-25 dihydroxyvitamin D, 25- hydroxyvitamin D

    One year

Study Arms (1)

Patients aged 5 years old and with a known diagnosis of a OGS

Sampling MethodNon-Probability Sample
Study Population

Patients aged 5 years old and over with a known clinical diagnosis of an overgrowth syndrome such as Klippel-Trenaunay Syndrome, CLOVE syndrome, Proteus syndrome, diffuse capillary malformation with overgrowth, or other unspecified OGS.

You may qualify if:

  • Age \> 5 years such that the patient is able to cooperate with the DXA scan or Xtreme CT
  • Known clinical diagnosis of an overgrowth syndrome such as Klippel-Trenaunay Syndrome, CLOVE syndrome, Proteus syndrome, diffuse capillary malformation with overgrowth, or other unspecified OGS.

You may not qualify if:

  • Age \< 5 years
  • Inability to comply with the scan
  • No or uncertain diagnosis of an OGS.
  • Prior bisphosphonate use
  • Systemic steroids in the past 6 months
  • Pregnant women
