[Diagnostic and prognostic value of the echo-Doppler and transcranial Doppler methods in the acute phase of ischemic ictus].

The ischaemic ictuses are a frequent pathology. For their annulling potentiality a quick etiopathogenetic diagnosis is necessary to institute a suitable therapy that limiting the extension of the cerebral damage. In this respect, it is fundamental the use of the duplex methods in real time together with doppler valuation of the neck vessels (carotid and vertebral) and of the intracranial big arteries. The direct observation of the endoluminal surface in the extracranial vessels and the valuation of the circulatory condition in the individual arterial districts explored give as important of haemodynamic information which, added to that obtained through a computerized axial tomography and the clinic, allows a correct diagnostic valuation with important effects on the therapy as well as a reliable prognostic formulation. Description of two clinical cases.
