Trauma to the soft palate is a uncommon event during childhood. Stroke following intraoral trauma is also rare, but has been well documented by the current literature as a potentially serious complication. In this article, we report 2 cases of posttraumatic internal carotid artery thrombosis depicted by imaging studies. We discuss pathogenesis, and the literature is reviewed.
RESUMO -Descrevemos caso de trauma penetrante na região oral em criança, evoluindo com oclusão da artéria carótida interna e déficit neurológico correspondente. A tomografia computadorizada e a ressonância nuclear magnética demonstram a oclusão completa da artéria carótida interna. Enfatizamos esta rara complicação de trauma oral, comum em crianças e discutimos os aspectos patogênicos.PALAVRAS-CHAVE: trauma oral, artéria carótida interna, trombose, oclusão, infarto, artéria cerebral média, aneurisma dissecante. Thrombosis of the internal carotid artery secondary to soft palate injury: case reportABSTRACT-Stroke following intraoral trauma is a rare complication of a common childhood injury. In the literature these complications have been well documented, however this condition is still infrequent. In order to alert the physicians about this possible injury we report our experience with one case. Computer tomography and magnetic resonance imaging evidenced complete occlusion of the internal carotid artery. Pathogenesis of this oral trauma is discussed.KEY WORDS: oral injury, internal carotid artery, thrombosis, stroke, occlusion, middle cerebral artery, dissecting aneurysm O ferimento na região palatina lateral ou peritonsilar pode ser benigno, aparentemente. A trombose da artéria carótida interna (ACI), resultante de trauma na região do palato mole e da região peritonsilar lateral é situação relativamente rara, grave, de proporções catastróficas em muitas das vezes 1 . As manifestações neurológicas ocorrem tardiamente num período de 1 a 60 horas decorridas do acidente [2][3][4] . As sequelas vão desde déficits mínimos à morte, ocorrendo esta em até 30% dos casos 3 .Relatamos caso de nossa experiência.
