Sneezing-Induced Subclavian Arterial Rupture: A Case of Vascular Ehlers-Danlos Syndrome in a Child.

Vascular Ehlers-Danlos syndrome is a fatal disease caused by a type III collagen mutation that can result in the rupture of blood vessels, the intestinal tract, and/or the uterus. Despite being the most severe form of Ehlers-Danlos syndrome, it is not well known in the pediatric context because it rarely presents serious complications in childhood. In this case, the patient experienced a subclavian artery rupture triggered by sneezing, which was initially managed with an endovascular stent. However, the descending aorta subsequently ruptured, and the patient died. Traditionally, surgical or endovascular treatments have been avoided due to the inherent fragility of blood vessels. Nevertheless, favorable outcomes have been documented with a wait-and-see surgical approach or endovascular treatment, especially when the diagnosis precedes the onset of vascular complications. Notably, celiprolol, a partial β2-agonist and β1-blocker, has demonstrated efficacy in preventing vascular complications. Therefore, early diagnosis plays a pivotal role. Raising awareness about this syndrome, along with its management and prophylaxis, holds the potential to enhance the survival rate.
