P26 TRANSIENT GLOBAL AMNESIA AS A POSSIBLE CONSEQUENCE OF ICA DISSECTION: A CASE REPORT

Abstract Case Report A 42–year–old woman was carried to emergency room lamenting sudden memory loss. Her husband witnessed the onset of episode. No recent head trauma reported, blood pressure under control. Anterograde and retrograde loss present confirmed by a neurologist. other neurological signs were elicitable. Blood exams toxicological analysis negative. ECG, chest radiography, cerebral TC showed no abnormalities. At physical examination carotid bruit could be appreciated. The patient asymptomatic. Subsequently an eco–colour–Doppler artery performed showing left common internal dissection. diagnosis ICA dissection with contrast CT furthermore excluding coexistence aortic anterograde amnesia resolved 15 h after admission. neurologist that experimented episode transient global amnesia. After vascular surgery consultation, conservative treatment deemed appropriate. 6 month follow up didn’t complain any symptom or sign. Transient (TGA) is characterized reversible resolves spontaneously within 24 h. pathophysiological mechanisms underlying this puzzling syndrome are yet not completely clarified. Some studies support ischemic aetiology for TGA cases following ICA–stenting involvement supra–aortic branches reported in literature, thus supporting hypothesis cause–effect relationship between pathologies trunks might present. In case here presented, Doppler ultrasound arteries presenting TGA, asymptomatic neck pain, led order miss spontaneous as rare ethology we suggesto perform epi–aortic vessels patients affected such amnesic syndrome.
