[Vascular Ehlers-Danlos syndrome]

Area of Science:

• Genetics
• Vascular Biology
• Connective Tissue Diseases

Context:

• Vascular Ehlers-Danlos syndrome (vEDS) is a rare, autosomal dominant inherited connective tissue disorder.
• It stems from mutations in the COL3A1 gene, affecting type III collagen production.
• This leads to a high risk of spontaneous arterial rupture, dissection, and visceral/obstetrical complications.

Purpose:

• To outline the clinical presentation and diagnostic criteria for vascular Ehlers-Danlos syndrome.
• To highlight key arterial and non-arterial findings suggestive of vEDS.
• To emphasize the urgency of diagnostic evaluation in patients with suspected vEDS and acute symptoms.

Summary:

• Diagnosis is primarily clinical, supported by characteristic morphological features and confirmed by COL3A1 gene mutation analysis.
• Suggestive arterial lesions include dissecting aneurysms (carotid, iliac, visceral aortic branches), splenic artery aneurysms, and carotid-cavernous fistula.
• Non-arterial signs like spontaneous peritonitis or severe perineal tears post-delivery warrant attention.

Impact:

• Prompt recognition and diagnosis of vEDS are critical due to the unpredictable and potentially fatal nature of arterial or organ rupture.
• Patients presenting with acute pain require immediate investigation (CT-scan or MRI) to rule out life-threatening complications.
• Understanding these features aids in timely management and prevention of catastrophic events in individuals with vEDS.
