About this trial

100 women with karyotype verified TS, previously examined at 4 study visits during a 19-year period will be asked to participate in a 5th study visit. Healthy age-matched females will be included as controls in a ratio 2:1.

The aim is to examine and quantify the cardiovascular and lymphatic system in women with TS. The investigators will study a possible causal mechanism between the known pathologic phenotype and alterations in these systems to understand, prevent or treat the life-threatening complications in TS.

Trial outcomes

Primary outcomes

1

Grade dysfunction of clinical and subclinical lymphedema using Indocyanine Green Lymphography and Magnetic Resonance Lymphangiography.

Lymphedema will be graded in a total score according to the International Society of Lymphology. The stages are: Stage 0: Subclinical lymphedema. • Stage 1: Early, reversible pitting edema. Stage 2: Irreversible lymphedema. Stage 3: End-stage lymphedema.

Time frame
3 year
2

Detecting low-grade inflammation in Turner Syndrome preforming FDG-PET/CT-scans to locate low grade inflammation.

Time frame
3 years
3

Heat maps of the distribution of wall shear stress in the aorta

Using 4D-flow analyses heat maps of the aorta will be made to illustrate the distribution of wall shear stress.
