Abstract
We examined 21 patients with ischemic cerebrovascular disease using magnetic resonance angiography and transcranial Doppler. In 17 patients (81%), the results obtained by the two methods were concordant. In our opinion, the associated use of transcranial Doppler and magnetic resonance angiography provides an accurate diagnostic evaluation of ischemic stroke patients, not only allowing the site of possible steno-occlusive disease of large and medium cerebral vessels to be identified, but also offering the possibility of obtaining dynamic information concerning the direction of blood flow in the presence of compensatory circulations at the level of Willis' circle.
Sommario
Abbiamo esaminato 21 pazienti affetti da patologia cerebro-vascolare ischemica con Angio-RM e Doppler Transcranico. In 17 pazienti (81%) i dati ottenuti con le due metodiche sono risultati concordanti. L'uso associato del Doppler Transcranico e dell'Angiografia a Risonanza Magnetica può permettere, a nostro avviso, una accurata valutazione diagnostica del paziente affetto da stroke ischemico consentendo l'individuazione della sede della eventuale patologia steno-occlusiva dei vasi cerebrali di medio e grosso calibro oltre alla possibilità di ottenere informazioni di tipo dinamico riguardanti la direzione del flusso ematico in presenza di eventuali circoli di compenso a livello del poligono di Willis.
