Abdominal aortic aneurysms: how can we improve their treatment?

Area of Science:

• Vascular Surgery
• Geriatric Medicine
• Cardiovascular Disease

Background:

• Arteriosclerotic abdominal aortic aneurysms (AAA) are prevalent in 2% of the elderly population in Western countries, with increasing incidence.
• Untreated AAA carries a high mortality risk; 80% of symptomatic patients die within a year, and rupture risk escalates with aneurysm size.
• Elective AAA repair offers improved survival, with 50% of patients living at least 5 years post-procedure.

Purpose of the Study:

• To highlight the prevalence and risks associated with abdominal aortic aneurysms.
• To emphasize the importance of early diagnosis and timely surgical intervention for AAA.
• To outline diagnostic methods and indications for AAA repair.

Main Methods:

• Review of existing literature on arteriosclerotic abdominal aortic aneurysms.
• Analysis of patient outcomes based on treatment (surgical repair vs. no treatment) and symptom presentation.
• Description of diagnostic modalities including physical examination, ultrasonography, CT, and aortography.

Main Results:

• Physical examination alone diagnoses AAA in 88% of cases.
• Indications for repair include symptomatic or ruptured AAA, and asymptomatic AAA > 5 cm.
• Symptomatic AAA presents with pain, distal embolism, thrombosis, or rupture.

Conclusions:

• Early diagnosis and referral for surgical repair are crucial for optimal management of abdominal aortic aneurysms.
• Surgical repair of AAA is associated with low mortality and improved long-term survival.
• Prompt intervention for symptomatic or large abdominal aortic aneurysms can prevent life-threatening complications.
