Aorta - Normal IVC to AA lateral drag - Longitudinal View
Caption
While maintaining its orientation, the probe is dragged to the left of the patient, revealing the abdominal aorta (AA) and the emergence of the coeliac trunk. Notice the contractile, thicker aortic walls and how both the common hepatic artery and splenic artery form the “seagull sign”. Also notice that a normal IVC frequently demonstrates transmitted pulsations from the RA; hence, pulsation is not the proper method for differentiating it from the aorta. This clip is taken over the subxiphoid region, longitudinally to the body’s axis, and with the probe marker oriented to the patient’s head.
