Clinical variability in children with dolichoarteriopathies of the internal carotid artery.

Abstract

Dolichoarteriopathies of the internal carotid artery (DICA) are frequent non-atheromatous anatomical changes in the general population. The etiology of DICA is still controversial: several hypotheses have been suggested, including an anomaly of embryological development, or a degenerative loss of elasticity of the vessel wall. DICA have been related to a wide spectrum of clinical presentations in adults, varying from asymptomatic forms to acute cerebrovascular events. However, to date, only a few pediatric cases have been reported. We report seven patients with DICA, 6 males and 1 female, aged 3 to 13years, presenting with variable clinical symptoms. Different imaging techniques, including color Doppler ultrasound and magnetic resonance angiography, were used to show loops and/or kinking of the ICA. Three of these patients received a diagnosis of Ehlers-Danlos syndrome (EDS). This study highlights the clinical variability in pediatric patients with DICA. We emphasize the need for close clinical management of pediatric DICA. Finally, considering the long-term prognostic implications of EDS, we recommend specific testing in children with DICA and suspicious clinical signs of this pathology.
