Abstract(s)

The non-atherosclerotic vasculopathies are an uncommon group of disorders, with diverse etiopathogenesis, involving younger patients when compared with atherosclerotic disease. Clinical presentation varies from acute vascular events - ischemic or hemorrhagic- to uncharacteristic neurologic syndromes. Although the cerebral angiography is the gold standard diagnostic method due to its high sensibility, its specificity is low mainly when compared to imaging evaluation of the arterial wall with carotid and vertebral ultrasound-doppler. We reinforce the importance of this non-invasive and radiation-free exam, not only in the diagnosis but also in the monitoring of these patients - young patients who need a regular and extended evaluation
