The swelling of the artery or a vein wall is an aneurysm. Due to the growth of an aneurysm, it exerts pressure on the nearby structures and ruptures. In several cases, people found out about the presence of an unruptured brain aneurysm as part of a scan required or for treating a different cause. The risk factor for the rupture depends on the location and the size. The conventional treatment options include a bypass, clipping, coiling, and observation.
Unruptured Brain Aneurysm
An unruptured brain aneurysm occurs in the brain, where the bulge of the artery wall occurs at any location in the brain. Over a period, the wall thickness decreases and the pressure exerted by the blood force causes the balloon or the bulge to break. Due to the break, the blood from the artery enters the void between the brain and the skull.
The occurrence of a brain aneurysm is due to the presence of large blood vessels. About 80% of the aneurysms form in the frontal lobe of the brain. The different types of aneurysms include Saccular, Fusiform, Traumatic, and Giant.
What Causes An Unruptured Brain Aneurysm?
Several studies state that there is an active link between the family history and the occurrence of an unruptured brain aneurysm. For instance, if an immediate member of the family has an episode of an unruptured brain aneurysm, it is likely that the individual suffers from the same. Although scientists or the doctors could not establish the genetic link for the cause, the case studies displayed that the presence of a brain aneurysm in the family history has the highest percentage.
Apart from family history, other inherited conditions also cause an unruptured brain aneurysm that includes Marfan’s syndrome, neurofibromatosis NF1, Ehlers-Danlos IV, and polycystic kidney disease. Doctors also recommend screening tests such as CT scan or MRI for people who have a strong medical history.
According to a survey, about 5% of the total population suffers from different aneurysms. Out of these, 20% have multiple aneurysms, and unruptured brain aneurysms are common than ruptured. Nonetheless, general physicians fail to identify the presence of an aneurysm until there is a rupture. People between 35 and 60 years have the occurrence, and the degree of the presence is high in women when compared with men.
Symptoms of Unruptured Brain Aneurysm
Most unruptured brain aneurysms do not have any symptoms. The release of the bled into the space surrounding the brain causes subarachnoid hemorrhage. It is here that the doctor is capable of finding out the presence of an aneurysm. However, when it is the case of an unruptured brain aneurysm, it is not possible to identify because unruptured brain aneurysm does not display any symptoms unless there is a growth in the size of an aneurysm. The following are the common symptoms experienced for an unruptured aneurysm:
- Double vision
- Dilated pupils
- Pain behind the ice
- Severe headaches
The screening test for an unruptured brain aneurysm plays a pivotal role in offering the right treatment. The diagnosis includes carrying out a computed tomography angiography, angiogram, and magnetic resonance imaging.
If the doctor senses that the size of a brain aneurysm is small and the risk factor for the rupture is low, then he will place the patient under observation. At the same point, he will offer instructions that will help in maintaining good health of the blood vessels along with overall health. Quitting smoking is a significant contributor to reducing the risk factor. Additionally, the treatment procedure changes for a woman, and especially for pregnant woman.
