The great IVC mimic!

Pitfall: Mistaking the descending aorta for the IVC is common pitfall, but the right hepatic vein can mimic the IVC too. Trace back to the RA, visualise the IVC-RA junction and the hepatic vein coming off the IVC.

Remember: IVC size & collapsibility are influenced by many factors (anatomical and physiological). It's NOT a direct measure of fluid status, it reflects right atrial pressure and to some extent TV competency.

Assess BOTH short & long axis! Don't forget the short axis – the IVC isn't a perfect cylinder.  #echotips #cardiotwitter #Scanuary
