Abdominal aortic aneurysm (AAA) is a localized dilatation or swelling of the abdominal segment of the aorta, the body’s largest blood vessel that transmits blood from the heart to the lower body. It happens when part of the aorta lining thins and lengthens, causing the channel to expand. If the aneurysm grows over time it may result in certain complications which are life threatening such as rupture of the aneurysm which causes internal bleeding.
Epidemiology
This epidemiological data is based on united states statistics.
In autopsy studies the frequency rate of AAA varies between 0.5% to 3.2%. In a cross-sectional study of over 1500 patients in screening of US veterans, the prevalence rate was found to be 1.4%. The probability of development of range is between 3-117 per 100,000 person-years.
AAA rupture is the 13th rank killer disease in the USA, and the estimated 15000 people die from the disease annually.
Anatomy
Pathophysiology
Degeneration of the Aortic Wall: The weakening of the connective tissue occurs through chronic inflammation and oxidation of the aortic wall as well as through the action of proteolytic enzymes, mainly matrix metalloproteinases.
Atherosclerosis: Even though it is not a direct cause, there are several ways that atherosclerosis may advance wall degeneration by promoting inflammatory cell infiltration.
Inflammation: Macrophages and T-lymphocytes are found infiltrating the vessel wall and liberate cytokines and enzymes that degrade the extracellular matrix, thus, weakening the aortic wall.
Hemodynamic Stress: The pressure in the blood flow or stream through the aorta and through other parts that have turbulence to them exert mechanical pressure to further weaken the aorta hence leading to dilation.
Etiology
Atherosclerosis (most common)
Chronic inflammation and lipid accumulation lead to degeneration of the aortic wall’s structural components, including elastin and collagen, weakening the vessel and promoting aneurysm formation.
Genetic predisposition
Medical history has revealed that people with family history of AAA are more prone to this disease indicating inheritance. Other connective tissue disorders (for instance Marfan syndrome Ehlers-Danlos syndrome) also increase aneurism risk.
Age
AAA develops mostly in patients over 65 years of age since the blood vessel walls become stiff with age and may easily expand.
Smoking
The most dominant of all the risk factors is smoking. It speeds up the process of atherosclerosis and increases the process of chronic inflammation of the aortic wall.
High blood pressure also damages the layer of aortic wall and hence it weakens and dilates.
Genetics
Prognostic Factors
Aneurysm Size:
Diameter: Larger AAAs (greater than 5.5 cm in men and 5.0 cm in women) are at higher risk of rupture.
Growth Rate: An expansion rate of more than 0. 5 cm/year is related to the rupture risk.
Age:
Patients more than 65 years of age have a higher risk of AAA rupture and associated comorbidities as well as postoperative complication.
Smoking:
Smoking directly correlates with development, progression and rupture of AAAs.
Clinical History
Age Group:
Men aged 65 and older: All guidelines support the mass AAA screening in men aged 65 to 75 years with a history of smoking.
Women: Women over the 65 years, who has smoking history or family history of AAA may be at risk and might need screening.

Acuity of presentation
Asymptomatic AAA:
No symptoms: Detected incidentally during imaging for another reason.
Management: More often, the process of monitoring depends on the size of the aneurysm. Elective surgery is performed when aneurysm has a size of 5.5 cm or more in diameter in the male, or 5.0 cm or more in diameter in females, or when it enlarges at a rate of 0.5cm in half a year.
Symptomatic but Unruptured AAA:
Symptoms: Some of the symptoms which may manifest because of this condition includes back or abdominal pain that may extend to the groin or lower limbs. Some of the patients may have feelings like thumping in the abdomen.
Management: This is a surgical emergency because it indicates impending rupture. Urgent repair is often necessary in this case.
Ruptured AAA:
Life-threatening emergency: Sudden, severe abdominal or back pain, hypotension, and shock. The mortality rate is very high, especially if the rupture occurs outside of a hospital setting.
Management: It becomes necessary to do an operative procedure, which may be an open repair or endovascular aneurysm repair (EVAR). Even with prompt surgery, mortality is significant.

Treatment Paradigm
Observation:
Small AAA (< 5. 5 cm in diameter): The follow-up is usually conducted with the help of ultrasound or CT scan, and it should be done every 6-12 months. Lifestyle changes and optimal control of other cardiovascular risk factors such as smoking, hypertension, etc. cannot be overestimated.
Medical Management:
Specific subgroups of AAAs include small/intermediate-sized AAAs and those patients who are not surgical candidates; therefore, the goal of treatment is to control the risk factors and aneurysm expansion. This includes antihypertensive drugs like beta blockers ACE, inhibitors, and statins.
Surgical Intervention:
Elective Repair: Suitable for AAAs (larger than 5. 5 cm in diameter often) or growing AAAs quickly.
Two main types of surgical repair are available:
Open Surgical Repair: Involves removing the aneurysm and replacing it with a synthetic graft. This is a more invasive procedure with a longer recovery period.
Endovascular Aneurysm Repair (EVAR): The process that involve insertion of a stent graft through minute incisions reached in the groin area to seal up the aneurysm. It is usually characterized by a shorter recovery period and minimal post-operative complications compared to open surgery.
Emergency Repair:
Ruptured AAA: In cases of a ruptured AAA, this is one of the surgeries that require emergency operations because the condition is life-threatening. A decision of patient’s operation can be treated between open surgery and EVAR based on some factors, including conditions of the patient and availability of resources.

Lifestyle Modifications:
Smoking Cessation: Smoking is one of the most influential causes of growth as well as rupture of AAA.
Diet and Exercise: A healthy diet is critical in the prevention of high blood pressure as well as other cardiovascular diseases.
Medical Interventions:
Regular Monitoring: Even after a patient has been diagnosed with having AAA, they need to undergo further imaging (for example, ultrasound or CT scans) to monitor size and growth of the aneurysm.
Education and Awareness:
Patient Education: Education about AAA, the risk factors associated with it and the necessity to stick to their treatment and lifestyle improvements should improve the results.
Effectiveness of Antihypertensives in treating AAA
Due to its short half-life, esmolol might be beneficial in cases of tachycardia and hypertension where a short acting agent is required. However, its primary use is not often used in the long-term management of the AAA. This is the reason why it is vital to control blood pressure and heart rate to lessen the stress in the aortic wall.
Labetalol falls under the category of non-selective beta-blocker
It has an impact on the heart rate and blood pressure. Compared to esmolol, it has a longer active time.
Labetalol may be appropriate for the long-term treatment of hypertension; it may also regulate both systolic and diastolic pressure. Thus, the sustained blood pressure control might be more suitable in AAA with the help of its use in this medication.
Morphine has a relatively slow onset, and a longer duration of action compared to fentanyl. It typically starts to work within 15-30 minutes and can last 4-6 hours.
It is common to prescribe the medication to patients who have moderate to severe pain. That can be used in AAA patients to treat the pain that may arise from post-surgery or caused by the symptoms that are related to the aneurysm.
Fentanyl Sulfate
Fentanyl is often preferred in acute settings or when rapid and potent analgesia is required. It can be particularly useful in the intraoperative setting or for severe breakthrough pain.
Role of Intervention with procedure in treating AAA
Intervention with procedure
Open Surgical Repair: This is the traditional technique whereby a long incision of the abdomen is made to directly expose and repair the aneurysm. A part of the damaged part of the aorta is replaced with a synthetic graft. Recovery time is longer because the process involves longer times; however, this procedure is commonly used when the aneurysm is large or complicated.
Endovascular Aneurysm Repair (EVAR): This is a less invasive technique: through a catheter placed through a small incision in the groin, it is guided to the area of the aneurysm. Inside the aorta, then a stent graft is placed to reinforce the weakened area and prevent rupture. Recovery time is generally much shorter compared to open surgery, and this technique is preferred for patients who are at a higher risk for open surgery.

Diagnosis and Assessment:
Screening: Screening is Often performed using ultrasound for high-risk groups (for example, men over 65 years of age, especially smokers).
Imaging: Establish the diagnosis, and size location often by Ultrasound, CT scans or MRI.
Surveillance:
Small AAA (typically <5.5 cm): Periodic or as-needed follow-up with simple imaging such as ultrasound or follow-up CT scans.
Medical Management:

Surgical Intervention:
Elective Repair: AAA >5.5 cm: Options include open surgical repair or endovascular aneurysm repair (EVAR).
Emergency Repair: For ruptured aneurysms requiring immediate surgical intervention.
Postoperative Care:
Monitoring: Imaging needed for the future to assess the success of the repair and to look for any complication.
Rehabilitation: Further support and maintaining the factors that would help to avoid relapse.
