Abstract:
Introduction. Ehlers-Danlos syndrome type IV, vascular type, represents mutations in the procollagen type
III (COL3A1) gene. Confirmation of the presence of a COL3A1 mutation and its nature can help evaluate
the risks of complications.
Aim of study. Elucidating the clinical-genetics aspects of Ehlers-Danlos syndrome type IV.
Methods and materials. To achieve the proposed objective, a synthesis of the literature published from
2009 to 2021 was performed using 30 bibliographic sources, including electronic libraries such as PubMed,
Medscape.
Results. Arterial events were defined by symptomatic dissections, aneurysms or spontaneous arterial
ruptures. Arterial ruptures or dissections are responsible for the majority of deaths. In childhood many
individuals with vascular type are first thought to have coagulation disorders. In adulthood, four main
clinical findings, including a striking facial appearance, easy bruising, the skin is abnormally thin and pale,
it is smooth, soft and velvety with multiple venous lesions.
Conclusion. Most affected patients survive the first and second severe complications, but Ehlers-Danlos
syndrome type IV leads to sudden premature death. The diagnosis should be assumed in young people
presenting to the doctor because of uterine rupture during pregnancy or arterial or visceral rupture. Early
diagnosis is particularly important for surgeons, radiologists and obstetricians because knowing the
diagnosis can help manage complications.
