Background:
Abdominal aortic aneurysm (AAA) remains one of the hallmark pathologies in vascular surgery and an area of intense research interest. Treatment options have expanded in recent years to increase the range of morphology suitable for endovascular aneurysm repair (EVAR), and with potential implications on treatment thresholds.
Objective:
This article is the first of two that will outline current treatment options for AAA, including areas of controversy and research in AAA disease, to inform the development of Australasian clinical guidelines and health policy.
Discussion:
Medical therapy options remain limited and no aneurysm-specific pharmacotherapy is currently available. Recent years have witnessed a significant shift in AAA surgery from open repair to EVAR and expansion of EVAR techniques. General management of cardiovascular risk factors remains key to reducing all-cause mortality for patients with AAA.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
