Diagnosing and treatment for brain aneurysm
There are several medical procedures which can be employed in order to detect brain aneurysm. These medical procedures are CT, CTA, LP and MRI as well as angiography.
Before the doctor prescribe the proper treatment several things must be taken into consideration, such as the location of aneurysm, the age of the patient, neurological state as well as the general health of the patient. If the brain aneurysm ruptures then the immediate professional help is required. The doctors should restore proper respiration and blood pressure. Furthermore, the bleeding must be stopped and the brain damage should be prevented. In the cases of unruptured small aneurysm, the medications are prescribed since the possibility of rupture is very small. Furthermore, the large brain aneurysm can be treated by a surgery. There are three kinds of surgeries for this condition: microvascular clipping, endovascular coiling and shunt surgery.
