HEALTH: AOTIC ANEURYSMS

​The AORTA is the largest artery in the body and is the largest blood vessel that carries oxygen rich Blood Away from the heart to all parts of the body. The section of the aorta that runs through the chest is called the THROACIC AORTA and as the aorta moves down through the abdomen it is called ABDOMINAL AORTA.

AORTIC ANEURYSMS  is an abnormal swelling in the major blood vessel that supplies the organ of the body; It is a less common condition that is associated with Hypertension and enlargement or bulging of the wall of the aorta. The two commonest sites to get them is the abdomen and in the chest where the blood vessels comes out of the heart because when the walls of the blood vessels are exposed to a higher Temperature for a long period of time, The walls become weak and the swell and it can cause two dangerous things; its either the balloon can burst and be dangerous or the living of the blood vessel can cause a linen in it.

According to Wikipedia, Most intact Aortic Aneurysm do not produce symptoms. As they enlarge, symptoms such as Abdominal pain and Back Pain may develop Compression of nerve roots may cause leg pain or numbness. However ,Aortic Aneurysms can be easily noticeable  mostly in Adults from 50 years and above with High blood pressure and Hypertension and it can be noticeable on People with Genetic Conditions, That is people born with weakness in the blood vessels known as MARFAN SYNDROME and the weakness causes Aneurysms mostly in the chest called THORACIC ANEURYSM also in the Abdomen called ABDOMINAL AOTIC ANEURYSM.

ABDOMINAL AOTIC ANEURYSM are more common than THORACIC ANEURYSM because the elastin, the principal load-bearing protein present in the wall of the aorta as compared to the Thoracic Aorta. Also, the abdominal aorta does not possess vasa vasorum, the nutrients-supplying blood vessels within the wall of the aorta. Abdominal Aortic Aneurysm involves three layers which are Tunica Intima, Tunica media and Tunica adventitia.

THORACIC ANEURYSM is a weakened area in the major blood vessel that feeds blood in the body(aorta). When the aorta is weak, blood pushing against the vessel wall can cause it to bulge like a balloon(ANEURYSM). Thoracic Aortic symptoms often grow slowly and usually without symptoms, making them difficult to detect. Some Aneurysm will never rupture. Many start small and stay small although some expand over time but it is difficult to predict how quickly an aortic aneurysm will grow.

According to a Swedish study reported in circulation ;Journal of the American Heart Association short term crude or actual survival rates improved among patients who underwent surgery to repair a ruptured abdominal aortic aneurysm. The relative survival rate held steady at about 87 Percent. On Average, patients who underwent repair for a ruptured aneurysm lived 5.4 years after surgery. However, researchers found difference in the repair of intact aneurysms. Relative survival was 10.2 percent higher among patients in their 80s than among this age 9 and younger 4. Percent higher for male patients than for female patients. Researchers said the survival gap between sees in intact repairs may be due to higher levels of Atherosclerosis (plaque buildup causing thickening of the arteries) in the female versus male patients.

According to a Consultant Interventional Cardiologist DrTosin Majekodunmi; Managing the hypertensive Aneurysm whether it ruptures or develops a tier called DISSECTION. If it ruptures then the chances of survival depends on how extensive that rupture is. If it is major rupture and the whole vessel burst its unlikely to survive. If you get a smaller Rupture that is contained, then you can operate immediately or put a stent across the Aneurysm to close off the Aneurysm and restore the integrity of the vessel walls.

To Treat or manage Artic Aneurysms is Surgery either open or endovascular. Medical Therapy is typically reserved for smaller aneurysms or for elderly frail Patients where the risks of surgical repair exceed the risks of non-operative therapy. Also, People who may have had High Blood Pressure or hypertension Are advised to treat it meticulously through scanning of the Abdominal Ultra sound every six or twelve months, cessation of smoking and also checking your blood Pressure which should be 130/80(mm Hg) or less and it should not be higher than that which is the ideal blood pressure.
