الشرح
Core Concept: Abdominal aortic aneurysms (AAAs) < 5.0 - 5.5 cm in asymptomatic patients have a low risk of rupture and are best managed with surveillance and cardiovascular risk factor modification.
Clinical Presentation:
- Usually asymptomatic, found incidentally on imaging or as a pulsatile abdominal mass.
Diagnosis:
- First-line tool: Abdominal ultrasound for screening and surveillance.
- Gold standard: CT angiography for precise anatomical measurement and pre-operative planning.
Management:
- Acute: Smoking cessation, blood pressure control, and statin therapy.
- Long-term/Definitive: Surveillance ultrasound every 6-12 months for aneurysms between 4.0 and 5.4 cm. Elective surgical or endovascular repair is indicated when the diameter reaches ≥ 5.5 cm or expands rapidly.
