Vascular Ehlers-Danlos syndrome (VEDS) diagnosis is a critical process that relies on a thorough evaluation of an individual’s medical and family history, coupled with a detailed physical examination. This examination is specifically designed to identify the presence of major clinical features associated with VEDS. Confirmation or exclusion of a Veds Diagnosis is then achieved through genetic analysis, which involves examining the DNA sequence of the COL3A1 gene. This genetic testing, crucial for accurate veds diagnosis, can be performed using DNA extracted from blood, saliva, or other tissue samples, and may include sequence analysis, deletion/duplication analysis, and biochemical testing.

It’s important to note that in many instances, a veds diagnosis only occurs after a significant medical event or even death. This highlights the likelihood that individuals and families with milder, less obvious symptoms might not seek medical advice, leading to undiagnosed cases of VEDS. Furthermore, due to the perceived rarity of Vascular Ehlers-Danlos syndrome, it is not always considered in differential diagnoses, and non-vascular symptoms may not immediately raise clinical suspicion for VEDS.
Genetic testing is highly effective, detecting approximately 98% of the genetic changes associated with VEDS. The remaining cases may require more specialized genetic tests to achieve a definitive veds diagnosis. Genetic testing is strongly recommended to confirm Vascular Ehlers-Danlos syndrome in individuals presenting with even just one major feature of the condition. A suspicion of VEDS should be raised in individuals exhibiting one or more major features, or several minor features, particularly in those under the age of 40.
Key Indicators for VEDS Diagnosis: Major Features
Certain major features are significant indicators that prompt further investigation and consideration of veds diagnosis. These include:
- Family History of Vascular Ehlers-Danlos Syndrome: A known family history of VEDS is a critical factor in assessing the likelihood of the condition in an individual.
- Arterial Rupture at a Young Age: Unexplained arterial rupture or dissection occurring in individuals under 40 years old is a major red flag for VEDS.
- Intestinal Rupture: Spontaneous rupture of the intestine in the absence of known diverticular disease or other pre-existing bowel pathologies is a significant major feature.
- Uterine Rupture During Third Trimester: Uterine rupture during the third trimester of pregnancy, particularly when not associated with a previous Cesarean section or severe vaginal tears, is a major indicator.
- Carotid Cavernous Sinus Fistula: The sudden onset of arteriovenous carotid cavernous sinus fistula, characterized by engorgement and redness of the eye and occurring without trauma, is another major feature.
Recognizing VEDS: Minor Features to Consider
In addition to major features, several minor features can contribute to the suspicion of VEDS and the need for further diagnostic evaluation. While less definitive on their own, the presence of multiple minor features, especially alongside any major feature or family history, strengthens the case for veds diagnosis. These minor features include:
- Easy Bruising: Frequent bruising that occurs spontaneously or with minimal trauma, and/or bruising in unusual locations such as the cheeks or back.
- Thin, Translucent Skin: Skin that is notably thin and translucent, leading to increased visibility of the underlying veins.
- Characteristic Facial Appearance: Specific facial features associated with VEDS, including thin lips, a small chin, a thin nose, and large eyes.
- Spontaneous Pneumothorax: Recurrent or unexplained pneumothorax, which is the collapse of a lung due to air or blood accumulation in the pleural space.
- Acrogeria: An aged appearance of the extremities, particularly the hands, known as acrogeria.
- Clubfoot: CongenitalTalipes equinovarus, commonly known as clubfoot.
- Congenital Hip Dislocation: Hip dislocation present at birth.
- Joint Hypermobility: Small joints exhibiting excessive range of motion beyond what is typically expected.
- Tendon or Muscle Rupture: Spontaneous rupture of tendons or muscles.
- Early Onset Varicose Veins: The development of varicose veins at an unusually young age (under 30 years old).
Who Needs VEDS Diagnosis?
Diagnostic studies for veds diagnosis are warranted in individuals with a family history of VEDS, arterial rupture or dissection before age 40, unexplained colon rupture, or spontaneous pneumothorax when accompanied by other features suggestive of VEDS. Genetic testing for VEDS should also be strongly considered when there is a combination of several minor clinical features.
Following a veds diagnosis in an individual, it is crucial to determine the genetic status of family members through clinical evaluation and molecular genetic testing. This comprehensive approach ensures accurate identification and appropriate management for those affected by Vascular Ehlers-Danlos syndrome.
