Coexistence of Vascular Ehlers-Danlos Syndrome and Sticky Platelet Syndrome: A Lethal Combination in A Young Patient with Thrombophilia and Haemorrhagic Diathesis.

Background: The coexistence of hypercoagulability and bleeding diathesis in the same patient represents a potentially lethal combination due to its complex management. Vascular Ehlers-Danlos syndrome (vEDS) and sticky platelet syndrome (SPS) are classified as rare diseases due to their low prevalence. vEDS is associated with bleeding tendencies caused by vascular wall fragility, while SPS is characterized by atypical arterial and venous thrombosis.

Case Report: We report a 27-year-old woman, smoker and regular consumer of energy drinks, with a medical history of subclinical hypothyroidism, minor thalassemia, recurrent joint sprains, high myopia, and anterior mitral valve prolapse, who was diagnosed with both vEDS and SPS type I. The patient experienced a catastrophic progression over a short time period, marked by numerous thrombotic and bleeding episodes, ultimately leading to a fatal outcome.

Conclusions: This report documents the first known case of concurrent vEDS and SPS, highlighting the complexity and challenges in the management of these two rare conditions together. The interplay between these syndromes necessitates careful clinical consideration and the development of tailored management strategies to mitigate associated risks. This underscores the crucial role of the internist in overseeing such cases. Further studies are needed to explore new therapeutic strategies aimed at improving survival rates and outcomes for patients with this unique combination of disorders.

Learning Points: The coexistence of vascular Ehlers-Danlos syndrome (vEDS) and sticky platelet syndrome (SPS) creates a unique clinical scenario where the underlying connective tissue weakness and platelet hyperaggregability synergistically increase the risk of both thrombotic and haemorrhagic events, complicating management strategies.Internists must assume a pivotal role in the integrated management of patients with vEDS and SPS, facilitating a multidisciplinary strategy that not only addresses the dual risk of thromboembolic and haemorrhagic complications but also emphasizes the importance of personalized treatment algorithms and ongoing surveillance to optimize long-term outcomes.
