POCUS IOTW: Portal Triad

Posted on: May 16, 2018, by :

The CBD is most easily identified through its association with the portal vein and the portal vein is most easily identified in the long axis of the gallbladder.  It is the ‘point’ of the exclamation point that is created with the gallbladder in the long-axis.

The CBD and hepatic artery will appear as two smaller circles anterior to the portal vein.  This is often noted as the “Mickey Mouse” sign!

I was born and raised in Silver Spring, Maryland, but with very little knowledge of all things DC. “Crabs and football, that’s what Maryland does”, unfortunately I could only partake in one of those. I grew up with a crab allergy so blue crabs are a make believe creature to me, much like the lochness monster. I decided to take the leap of faith and attend medical school abroad but family and home could not keep me away for too long. Residency took me to New Jersey where I began to cultivate my love for medical education and low tolerance for poor pain control. Did I mention I also learned that I outgrew my crab allergy in NJ! Alas, to the DMV I return! Hopefully to contribute to medical education and quality improvement while feasting on a Maryland blue crab or two.
