Pathology Of The Posterior Circulation

The echocolor Doppler of the intracranial arteries is a noninvasive method for quantifying the severity of the intracranial stenosis.

The possibility of studying and monitoring the vertebro-basilar vessels using ultrasound is important for diagnosis, prognosis and therapy: the presence of vertebro-basilar stenosis identifies a group of patients with posterior circulation stroke who are at high early recurrent stroke risk.

In this lesson the echocolor Doppler findings that support the diagnosis of a stenosis, occlusion, dissection of the intracranial vertebral arteries and the basilar artery are reported.
