Reversible cerebral vasoconstriction syndrome (RCVS)
Reversible cerebral vasoconstriction syndrome, sometimes called
Call-Fleming syndrome is defined as a condition of disease of the
arteries of which the brain develops a blood vessels spasm that leads to
multifocal arterial constriction and dilation, causing the sudden onset
of a severe headache (2)
Diagnosis
1. Catheter angiogram
Catheter angiogram, is the use of a thin plastic tube, called a
catheter, is inserted into a large artery and threaded through the
circulatory system to the carotid artery, through a small incision in
the skin, together with X-rays and a contrast dye in visualizing the
blood vessels of the brain. Then a series of radiographs
is taken as the contrast agent spreads through the brain's arterial
system, then a second series as it reaches the venous system.
2. CT scan
CT scan can dive
your doctor a three-dimensional view of your blood vessels of the brain to look for masses and other abnormalities that
cause Reversible cerebral vasoconstriction syndrome
3. Magnetic resonance imaging (MRI)
By
using radio waves and magnetic fields to take pictures, MRI scan
provides very high quality of a cross-sectional slice and lengthwise
slices of the brain and thus providing the better and detail image of
location of tumor and the surrounding structures. It is one of most
likely early test ordered by a doctor to diagnose tumors, strokes,
aneurysms, neurological diseases and other brain abnormalities and the
blood vessels around the brain.
4. Computed tomography angiography (CTA)
CTA is a test to create detailed images of the blood
vessels of the brain to look for neurological diseases and any
abnormality with the use of the combination of the technology of a
conventional CT scan with
that of traditional angiography.
5. Cerebral magnetic resonance angiography (MRA)
Magnetic resonance angiography (MRA) is an accurate non-invasive tool
for imaging the cerebral vessels. It provides morphologic information
about the cerebral vessels relying on blood flow as the physical basis
for generating contrast between stationary tissues and moving spins.
'Selective' MRA gives functional information about the cerebrovascular
system such as flow direction, origin of flow, and presence or absence
of collaterals. Arteries and veins can be imaged selectively due to
their usually opposite flow directions. Although at a relatively early
stage of development, MRA has already become a widely used tool for the
study of the cerebrovascular system(12)
In the study of One hundred five (79%) of all 133 aneurysms detected
with MRA by a
neuroradiologist, 100 (75%) detected by an experienced
neurosurgeon, 84 (63%) detected by a general radiologist, and 80
(60%) detected by a resident neuroradiologist, conducted by Nagatomi
Neurosurgical Hospital, found that although MRA is useful in the
diagnosis of cerebral
aneurysms, sufficient experience and careful attention are necessary
for accurate diagnosis of aneurysms located at the internal carotid and
anterior cerebral arteries(13)
