Updates on Ultrasonography Imaging in Abdominal Aortic Aneurysm

Area of Science:

• Vascular Surgery
• Medical Imaging
• Diagnostic Ultrasound

Background:

• Abdominal aortic aneurysms (AAAs) pose a significant rupture risk, leading to high mortality.
• Current screening relies on ultrasonography to measure aortic diameter, a key rupture predictor.
• Limitations exist, as some AAAs rupture at smaller diameters, necessitating improved predictive methods.

Purpose of the Study:

• To review current trends and emerging technologies in AAA assessment using ultrasonography.
• To explore ultrasonography's potential for predicting AAA rupture independently of diameter.
• To evaluate ultrasonography as an alternative to computed tomography angiography for post-EVAR surveillance.

Main Methods:

• Review of current literature on ultrasonography in AAA assessment.
• Analysis of studies investigating aortic wall strain for rupture prediction.
• Comparison of ultrasonography with computed tomography angiography for endovascular aneurysm repair (EVAR) surveillance.

Main Results:

• Ultrasonography is effective for AAA screening and diameter measurement.
• Aortic wall strain assessed via ultrasonography shows potential for predicting AAA rupture.
• Ultrasonography offers a radiation-free, contrast-free alternative for post-EVAR surveillance.

Conclusions:

• Ultrasonography is a valuable tool for AAA screening and management.
• Aortic wall strain analysis represents a promising advancement in AAA rupture prediction.
• Ultrasonography presents a viable alternative to CTA for EVAR surveillance, mitigating risks associated with contrast and radiation.
