Arterial pseudoaneurysms of the neck are rarely reported in the pediatric population and no dedicated large series are available. Trauma and infection are the most common causes for these aneurysms, with congenital and collagen vascular disorders being the less common causes. These lesions can be life threatening, especially when they present with bleeding or airway compromise. ⋯ Endovascular means of treatment for pediatric neck aneurysms is relatively simple and safe. Although parent vessel sacrifice is the gold-standard management, vessel-preserving strategies can be tried in select cases with favorable anatomy.

The relationship between superior cervical ganglia (SCG) ischemia due to bilateral common carotid artery ligation (BCCAL) and basilar artery (BA) reconfiguration was investigated. ⋯ A meaningful and paradoxic correlation was detected between the BA VDI values and degenerated neuron density of SCG after BCCAL. Although a low degenerated neuron density within SCG may provoke excessive sympathetic activity and prevent excessive BA dilatation with steno-occlusive carotid artery diseases, a high degenerated neuron density may cause dangerous vasodilatation of BA.
