Classical Ehlers-Danlos syndrome (cEDS) is one of the 13 subtypes of Ehlers-Danlos syndrome, which has the major clinical criteria of hyperextensibility skin, atrophic scars, and generalised joint hypermobility. The occurrence of aortic dissection has been described in some subtypes of Ehlers-Danlos, but it has a rare association with the cEDS subtype. This case report discusses a 39-year-old female with a past medical history of transposition of great arteries with a Senning repair at the age of 18 months and controlled hypertension with medication, who presents a spontaneous distal aortic dissection. The diagnosis of cEDS was made using the major criteria, and a novel frameshift mutation in COL5A1 was discovered. The reported case emphasises that in patients with cEDS, vascular fragility may be a complication.
Learning points:
Classical Ehlers-Danlos is a rare autosomal dominant inherited connective disorder.Arterial dissections are rarely found in cEDS patients.Association of cEDS and vascular fragility can result from new type V collagen mutation.
