Aorta - AAA with Intramural Thrombus
Caption
The patient presented to the ED with a known abdominal aortic aneurysm (AAA). A point-of-care ultrasound (POCUS) examination of the abdominal aorta was performed using a curvilinear probe (longitudinal view shown). An infrarenal AAA was noted adjacent and superior to the bifurcation and measured a maximum diameter of approximately 5cm. Heterogeneous echogenic material was seen within the lumen of the aneurysm in keeping with intramural thrombosis, along with a hyperechoic line representing a chronic dissection. This demonstrates the utility of POCUS in the rapid diagnosis of AAA and evaluation of size and intraluminal features such as intramural thrombus and dissection.
