Surveillance and monitoring in vascular Ehlers-Danlos syndrome in European Reference Network For Rare Vascular Diseases (VASCERN).

Vascular Ehlers-Danlos syndrome (vEDS) is a rare genetic disorder clinically characterized by vascular, intestinal and uterine fragility and caused by heterozygous pathogenic variants in the COL3A1 gene. Management of patients with vEDS is difficult due to the unpredictability of the events and clear recommendations on the care of adults and children with vEDS are lacking. Therefore, we aimed to collect data on the current strategy of surveillance and monitoring of vEDS patients by expert centers in continental Europe and Great Britain, as a first step towards a consensus statement. A survey on the clinical management of vEDS was sent to all members of the Medium Sized Artery (MSA) Working Group of the European Reference Network for Rare Vascular Diseases (VASCERN) and other expert centers. All experts endorse the importance of monitoring patients with vEDS. Despite the absence of evidence based guidelines monitoring is considered in almost all countries, but screening intervals and modalities used for monitoring may differ among centers. There is a need for more prospective multicenter studies to define proper guidelines.
