Clinical Causes: Atherosclerosis (build-up of fats, cholesterol, and other substances in the arterial walls) Genetic factors and family history of aortic aneurysms Smoking, which damages blood vessels and accelerates artery wall weakening High blood pressure (hypertension), contributing to vessel stress Age-related degeneration of the arterial walls, particularly in older adults Infections or inflammatory diseases affecting blood vessels

Key Symptoms: Often asymptomatic in early stages; many cases are discovered during routine medical examinations A pulsating sensation or mass in the abdomen Deep, persistent pain in the abdomen or back Discomfort or fullness in the abdomen In some cases, symptoms related to compression of nearby structures, such as urinary or gastrointestinal issues

Diagnosis Path: Diagnosis typically involves imaging tests that visualize the aorta. These may include: - Ultrasound: The primary and most common screening tool for detecting AAA - Computed Tomography (CT) scan: Offers detailed images to evaluate the size and extent of the aneurysm - Magnetic Resonance Imaging (MRI): Used in specific cases for detailed vascular imaging Regular monitoring of aneurysm size is crucial to assess risk and guide management strategies.

Treatment Protocols: Management of a non-ruptured abdominal aortic aneurysm depends on its size and growth rate: - Observation: Small aneurysms, generally less than 5.5 centimeters in diameter, may be monitored regularly to track growth - Lifestyle modifications: Quitting smoking, controlling blood pressure, and managing cholesterol levels to slow aneurysm progression - Surgical intervention: Larger or rapidly growing aneurysms may require procedures such as: - Open surgical repair: Removal of the aneurysm with graft placement - Endovascular aneurysm repair (EVAR): Minimally invasive procedure involving placement of a stent-graft via small groin incisions Follow-up is essential post-treatment to monitor for potential complications or recurrence.
