Current status and progress in the treatment of small abdominal aortic aneurysms / 国际外科学杂志

ABSTRACT

The abdominal aortic aneurysm with a diameter of 3.0-5.4 cm is called small abdominal aortic aneurysm.Generally asymptomatic,there is no evidence-based medical evidence that surgery or endovascular repair is better than follow-up observation.Small abdominal aortic aneurysms are managed by regular CT or ultrasound surveillance until they grow to a diameter threshold (commonly 5.5 cm) at which surgical intervention is considered.But these patients without surgical intervention remain risk of rupture.We briefly summarized the current situation and progress of treatment on sAAA.
