Every year about 200,000 people will be diagnosed with an Abdominal Aortic Aneurysm better known as an AAA. A ruptured AAA is the 15th leading cause of death in the country. An aortic aneurysm occurs when the walls of the main blood vessel that carries blood away from the heart dilate. An AAA is located in the abdomen which is the most common site for aneurysms. When aneurysms are enlarged they can rupture and cause hemorrhaging within the abdominal cavity which constitutes as a medical emergency that requires immediate interventions.
Unfortunately, an AAA tends to grow slow and present without symptoms making them difficult to diagnosis. However, the larger the aneurysm becomes patients may notice a pulsating feeling near the navel, …show more content…
Although the exact cause of an AAA is unknown there are some risks factors that may contribute to the condition that include tobacco use, atherosclerosis, high blood pressure, infection of the aorta, trauma, heredity, age, gender and race. Since a ruptured AAA accounts for 15,000 deaths annually it is recommended for people who fall within the high risk category to have a routine abdominal ultrasonography completed to treat the aneurysm before it ruptures.
To repair an AAA, the section of the abdominal aorta that is dilated is removed and replaced with a graft. To perform the procedure, the patient is placed in the supine position and sedated with general anesthesia followed by skin preparation and draping. The surgeon will then make an incision down the center of the abdomen from the breastbone to the below the navel or across the abdomen from underneath the left arm to the center of the abdomen down to navel.
After dissection and the aorta is located a clamp is placed above and below the aneurysm. The aneurysm sac is then cut open and the graft is sutured into place. After the clamps are removed the walls of the aneurysm are wrapped around the graft and the aorta is sutured back

Endovascular Surgery

Endovascular repair of abdominal aortic aneurysm ( EVAR )was introduced a decade ago. This operation involves radiographically guided intraluminal placement of a prosthetic graft on a wire mesh into the abdominal aorta. This is done via a small groin incision thus avoiding the morbidity and mortality associated with major open abdominal surgery. As with conventional repair the goal of endovascular treatment is to prevent further expression by excluding flow within the aneurysm thus reducing the risk of…

childhood period (4). Conventional CABG is usually performed in children; off-pump CABG is rarely preferred for use in pediatric patients because of the small diameter of their vessels (5). Extracardiac vascular involvement (including that involving the aortic root and carotid artery) has been documented in children with familial hypercholesterolemia and the incidence of such involvement increases with the age of the patient. Evaluation for atherosclerosis of the aorta is not routinely performed preoperatively…

Cardiac MRI: Magnetic Resonance Imaging Analysis

• Echocardiogram: A microphone-like transducer is placed on the chest to record images of the heart using sound waves. The study gives important information about the structure and function of the heart and carries no risk. It is an excellent test by which to measure LVEF. • Cardiac MRI: Magnetic resonance imaging (MRI) of the heart can provide very detailed images of the heart muscle and its components. It may detect subtle abnormalities of the heart muscle that other diagnostic testing cannot.…

Adequate Coronary Syndrome (ACS)

ACUTE CORONARY SYNDROME The term acute coronary syndrome (ACS) is a sort of umbrella term that is used to define symptoms and signs of myocardial ischemia. This ischemia includes unstable angina and non-STEMI, where arteries are only partially occluded and STEMI, where arteries are completely occluded. The acute coronary syndrome can present in a patient for the first time or in a patient with a history of stable angina. The underlying pathology for both unstable angina and MI is usually rupture…
