ABDOMINAL ULTRASOUND
are available, ultrasound can be a time-saving triage
tool to exclude an aneurysm from the differential
diagnosis of abdominal pain. Suitably trained
emergency department clinical staff can perform
this quickly and successfully. 19 Rupture of an aortic
aneurysm is a catastrophic event, and although an
urgent contrast-enhanced CT can be helpful,
emergency surgery based on clinical findings
should not be delayed by imaging investigations.
Ultrasound is also the first investigation of
choice for demonstrating suspected psoas abscess
or haematoma 20 (Fig. 10.6).
