To begin scanning, position the patient's supine with the abdomen exposed. Hip flexion, if tolerated by the patient, relaxes the abdominal muscles and may improve image acquisition. Apply ultrasound gel to the transducer.
Place the transducer transversely in the proximal abdomen, and the transverse plane, with the indicator toward the patient's right. Ensure that the indicator position matches the one displayed on the screen. Starting in the subxiphoid area, scan to obtain a transverse view of the aorta.
Once the transverse view of the aorta is optimized, rotate the probe clockwise with the indicator pointing towards the patient's head. Following the aorta as the image becomes longitudinal on the screen. Acquire images while scanning caudally, examining for aneurysmal dilations, and save these images for later review by clicking the button on the system that records clip.
To obtain a longitudinal view of the aorta in the coronal plane, if possible, position the patient in the left lateral decubitus position for better image acquisition. Place the transducer in the coronal plane at the mid axillary line on the patient's right with the indicator pointing cranially. Scan the aorta in the coronal plane.
The aorta will be visualized deep into the IVC if both vessels are imaged. The abdominal aortic pseudo thrombus was a reverberation artifact resulting from the reflection of the ultrasound beam between the anterior and posterior walls of the SMA.
