The use ofcolor and/or power doppler ultrasound in the assessment of non-atherosclerotic vasculopathies is of great importance because: - It is a helpful diagnostic tool; - It is an inexpensive imaging technique; - It is radiation-free and non-invasive; - It allows a frequent and feasible monitorization of the disease,
which is an important aspect,
because many of these patients are young and need a lifetime follow-up. It is also important to note that there are some disadvantages:it is...
The non atherosclerotic vasculopathies are an uncommon group of disorders,
with diverse etiopathogenies,
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...
Findings and procedure details
Moya-moya disease: Described in the English literature by Japanese neurosurgeons in the 1960's,
moya-myoa disease (MMD) is a chronic,
occlusive cerebrovascular disease characterized by progressive stenosis at the terminal portion of the internal carotid artery (ICA) and an abnormal vascular network at the base of the brain .The term “moyamoya” is derived from a Japanese expression for something hazy,
like a puff of cigarette smoke drifting in the air. The diagnostic criteria ,
The ultrasound-doppler technique is an alternative exam to the cerebral angiography,
with a high diagnostic capacity (sensibility and specificity),
being the method of excellence in the monitoring the arterial wall disease.
