Thoracic vascular anomalies are highly prevalent (~50%) in Turner Syndrome and are associated with specific physical phenotypes (neck webbing, increased chest diameter), highlighting the need for careful cardiovascular screening.
Thoracic vascular anomalies are common in TS, occurring in approximately 50% of a group not preselected for cardiovascular disease. The highly significant association between neck webbing, increased chest diameter, and these vascular anomalies suggests that in utero, centrally localized lymphatic obstruction may contribute to these cardiovascular deformities in TS. Improved recognition of these often-undetected vascular lesions may be important for identification of patients in need of closer cardiovascular monitoring.
