Splenic Artery Aneurysms

Splenic artery aneurysms (SAAs) are a rare arterial disease (1) and defined as a diameter of more than 50% of expected (0.9 - 1 cm) splenic artery diameter. Â They account for 60-70% of visceral artery aneurysms making them the most common of this group (4). Â They are often difficult to diagnose due to their vague or non-existing symptoms but present a high risk of rupture in certain patient groups making this a clinically important differential diagnosis.
