Mickey Mouse sign (ultrasound)

Last revised by Dagnechew Degefu on 18 Jul 2023

The Mickey Mouse sign is said to represent the normal anatomy of the common femoral artery, common femoral vein and great saphenous vein on ultrasound at the level just inferior the inguinal crease. 

Identification of the Mickey Mouse sign can be valuable for vascular procedures such as venous access, diagnostic evaluations, and surgical interventions in the lower extremity. Recognising this anatomical landmark ensures accurate measurement of blood flow, appropriate placement of catheters or other devices, and minimises the risk of complications during procedures.
