[Traumatic dissection of the internal carotid artery following whiplash injury. Diagnostic workup and therapy of an often overlooked but potentially dangerous additional vascular lesion]

Abstract

We report on the case of a 33-year-old male patient who was brought to the emergency room of our hospital after suffering a high-energy trauma due to an automobile accident. Besides a scaphoid fracture there were no signs of any neurological deficits. After several hours without clinical symptoms the patient developed dysarthria as the first manifestation of local cerebral ischemia based on a traumatic dissection of the internal carotid artery. Under systemic high-dose heparin therapy, fast and complete remission of all neurological disorders could be achieved. In the course of time a dissecting aneurysm developed. Temporary anticoagulation with phenprocoumon was started in the meantime and no further complications have appeared up to now. Besides presenting this absorbing case, this article highlights the diagnostic and therapeutic regime in cases of a traumatic dissection of supra-aortal arteries for rapid and adequate management of this rare but potentially dangerous complication.
