The diagnosis of brain hemorrhage due to brain aneurysm is easily made with examination findings and brain tomography. In rare cases, bleeding may not be visible on brain tomography, and definite bleeding can be demonstrated by taking water from the waist with a lumbar puncture. Once bleeding is detected, the vascular problem causing it must be investigated.
Brain Angiography:
This test is the most valid method that has been valid for years in showing the presence of aneurysms. Although mild sedation with medication may sometimes be needed during the procedure, it can generally be done while the patient is awake.
While the patient lies on the examination table, the person who will perform the angiography enters the artery from the groin with a thin needle. A small plastic tube (catheter) is then placed into the vein. The passage of the catheter is visualized under x-rays and proceeds to the head and neck region, where the four main brain vessels are located. There is no pain during this procedure. Visualizable intravenous dye is administered separately to each cerebral artery, and x-ray images are taken at this time. This application allows the vessels to be seen clearly.
After the angiography images are taken, the catheter is removed and a pressure dressing is applied to the removed area to prevent blood leakage. After a period of observation, the patient is sent to his bed. The patient does not feel the passage of the catheter during the procedure, but during the administration of the dye used, a vague feeling may occur on one side of the head or may cause temporary stargazing or neck cramps. Although the angiography process is sensitive and specific in detecting brain aneurysms that can put a person's life at risk, it is ultimately an invasive procedure for the patient and carries a low risk of damage to the vessel wall, stroke, and allergic reaction to the dye used.
Computed Tomography-Angiography (CTA):
Images similar to conventional angiography are taken by administering contrast material through the vascular access in the patient's arm. Transactional risk It is the allergy that the contrast medium may cause and the potential damage it may cause to the kidneys, which is also explained in conventional angiography. An important advantage of this method is that there is no need to transfer the patient to the angiography unit and there is no need for additional personnel. The extraction process is completed in less than a minute and carries no risk of stroke. By making the images obtained three-dimensional, more detailed information can be obtained about the shape of the aneurysm.
Magnetic Resonance Angiography (MRA):
It is a test that can be performed with an MRI device and does not cause any harm to the patient. Magnetic images are analyzed by a computer and the veins of the head and neck region are displayed. MRA shows actual blood vessels and can provide clear information about blocked, narrow vessels and aneurysms.
