Spontaneus resolution of a traumatic vertebral artery pseudoaneurysm

Abstract

Injuries of the vertebral artery are rare and are usually seen after penetrating or blunt cervical trauma. Vertebral artery injuries (VAI) have been reported in 0.5% of blunt trauma cases. These injuries can lead to hemorrhage, thrombosis, arteriovenous fistula or traumatic pseudoaneurysm in the early or late period. They must be treated carefully due to their increased risk of morbidity and mortality. In this case report, we present a case of asymptomatic traumatic vertebral artery pseudoaneurysm(TVAP) seen after cervical spinal trauma with C5-C6 listhesis developing afterwards, treated with anterior-posterior stabilization and fusion. Spontaneous resolution of the pseudoaneurysm is demonstrated by vertebral arter angiogrphy.
