Cerebral aneurysm is a weak part of the wall of a brain vessel that bulges and becomes a balloon due to high blood pressure. In most cases, this disease is asymptomatic until the end of life, but in rare cases, it enlarges and gradually affects the patient by pressing on the surrounding tissues. What are the symptoms of brain death? The symptoms of a brain aneurysm depend on its condition, location, and size. For example, a ruptured aneurysm gives the patient such a severe and sudden headache that it is sometimes called the worst headache they have ever experienced. In addition, other symptoms such as nausea and vomiting, neck stiffness, impaired vision, sensitivity to light, seizures, drooping eyelids, loss of eyelids, and loss of dizziness also occur. It can be asymptomatic and even If it is uniform, it can be diagnosed randomly, but if it is large and puts pressure on the surrounding tissues, it can make the patient suffer from symptoms such as pain behind and above the eye, dilated pupils, impaired vision, impaired speech, and even numbness on one side of the face. are....Approximately 15% of people with ruptured aneurysms die before reaching the hospital..Since in most cases, brain aneurysms are diagnosed with no symptoms..Head and neck area....But in general, the presence of aneurysms can be detected by imaging with CT scan (CT scan), MRI (MRI) and angiography....Also, if the doctor suspects aneurysm rupture, he can test the cerebrospinal fluid and test it for Find blood in it to notice it... According to WebMD magazine, aneurysms tend to develop in branches of blood vessels because those parts are weaker.. As a result, they usually develop at the base or base of the brain.. ### Brain Aneurysm Risk Factors Some of these risk factors are acquired, and some of them have been present since birth, but in general, by reducing the resistance of blood vessels, they cause an aneurysm in an area of ​​the vessel.. Aneurysm, AVM disease and polycystic kidney disease are some of the things that are inherent and increase the possibility of having an aneurysm.... ### Brain aneurysm in pregnancy If a neurologist diagnoses an aneurysm, he will follow it up as soon as possible and prioritize the life of the mother, because pregnancy is not one of the cases in which diagnostic and therapeutic measures of neurosurgery or neurosurgery are prohibited. The rate is relatively higher in pregnancy. It depends on its size, type and location... These treatments include the following: - #### Cut: In this method, the doctor must open the skull and clamp the neck of the aneurysm with a special clip to stop the blood flow to that area... #### Coil: This is a less invasive treatment in which the doctor inserts a catheter into the patient's groin vein and uses it to deliver a coil or platinum coil to the aneurysm site... When the coil reaches the desired location, it fills the extra space and prevents blood from entering it... If none of the above could work well due to the size of the aneurysm, the doctor uses this method, in which by placing a stent in the blood vessel, the stent acts like a new wall and prevents blood from reaching the aneurysm by changing the blood flow from that area. It reduces the possibility of it bursting by lowering the blood pressure and not putting pressure on yourself, especially when moving heavy objects...
