- How Does the Doctor Figure out Where Bleeding in the Brain Is?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I know that x-rays are useful for making many diagnosis, but I have
- been told that they are of little use in diagnosing bleeding in the brain.
- But then how does the doctor figure out where the bleeding is, and what can be
- done for it if this turns out to be the problem? We have just bee through a
- case like this but are still completely confused.

- ANSWER: Almost every kind of bleeding with in the brain tissue is called
- "intracerebral hemorrhage". When the blood remains pooled together in a
- well-localized superficial location it may be termed a "hematoma". Before the
- development of some incredible technology, particularly the CT scan (computed
- tomography) physicians relied on the different clinical patterns and symptoms
- that occurred as a result of the bleeding to determine the location. However
- these symptoms might also be caused by the mass effect of the hematoma,
- swelling (edema) of the brain from the irritation, the shifting of the brain
- as well as the extension of the bleeding to the ventricles (cavities within
- the brain). Performing a spinal tap (withdrawing fluid from the spinal
- column) could also reveal the presence of blood, a sure sign of bleeding
- somewhere in the central nervous system. Now the CT scan can localize small
- areas of bleeding with excellent precision. The single greatest cause for
- brain hemorrhage is hypertension, and the incidence of hypertension in such
- patients ranges from 25 to 94 percent. The medical treatment may therefore be
- directed at lowering the blood pressure, to reduce the amount and possibility
- of bleeding. However once the size of the hemorrhage has reached its maximum
- in about 1 to 2 hours, reducing the blood pressure will do little to reduce
- the size of the hemorrhage. When edema strikes the brain tissue and the
- pressure within the skull rises, additional techniques including the use of
- corticosteroids may be used. Finally surgical techniques must be considered
- in many cases. They can be used to remove the accumulated blood (hematoma),
- find the area of bleeding and stop the hemorrhage, and finally drain both
- blood and fluid away to lower the intracranial pressures. The decision to
- employ surgery will also depend upon other medical factors, and the patient's
- age and state of health.
