BACKGROUND: Vascular Ehlers-Danlos syndrome (vEDS) is a hereditary connective tissue disorder associated with an elevated risk of vascular, uterine and digestive complications. Managing pregnancy in this context can be a challenge.
OBJECTIVE: To systematically review the literature data on the complications in pregnancy associated with vEDS.
METHODS: We searched the Pubmed Medline and Embase databases for articles using the following terms \"vascular Ehlers-Danlos syndrome\" or \"vEDS\" AND \"pregnancy\".
METHODS: Women with vEDS.
METHODS: We searched the PubMed® MEDLINE® database for publications evaluating obstetric outcomes in women with vEDS.
RESULTS: A total of 121 publications were screened, with six (accounting for 412 pregnancies) included in our review. Of the women included in this sample, 30% were infertile. The miscarriage rate was 13.8% (57/412) and 8.8% of the live births were premature. Obstetric anal sphincter injuries occurred in 11.3% (23/203) of the deliveries. The maternal mortality rate per pregnancy was 5.7%.
CONCLUSIONS: Women with vEDS present an elevated risk of uterine rupture, vascular events, digestive events and death during pregnancy. Women appear to be most at risk during the peripartum period; to avoid expulsive efforts, a caesarean section should be scheduled at 37 weeks of gestation.

Patients with null variants may have milder vascular Ehlers-Danlos syndrome, presenting with seemingly non-specific complaints and subtle cutaneous features that may be missed. A high index of suspicion and early genetic testing (aided by next-generation sequencing) were crucial for prevention of life-threatening complications in the patient and family members.

In this report, we present the case of a 3-year-old child with vascular Ehlers-Danlos syndrome (vEDS) previously known as Ehlers-Danlos syndrome type IV. After experiencing a minor traumatic injury to the abdomen, consisting of falling over a bathroom stool on the way to the restroom with a full bladder, the child developed acute abdominal pain. He was found to have an intraperitoneal bladder rupture that was successfully repaired with management techniques tailored to his known diagnosis of vEDS. While tissue fragility and internal organ rupture occurring with minor trauma are known complications of vEDS, this is the first case in the literature of a bladder rupture in a child with vEDS with a confirmed variant in the COL3A1 gene, to our knowledge. This case broadens the clinical presentation of vEDS, demonstrates that children can have life-threatening organ rupture at a young age, and may alert providers to consider this diagnosis when a child presents with bladder rupture.
