caput medusae

This leads to a condition called Caput medusae.

Dilation of this particular portacaval anastomosis results in what is referred to as caput medusae.

Caput Medusae (uranography), one of the obsolete constellations.

The phrase Caput Medusae is Latin for "head of Medusa".

This spares the portal venous system from high pressure which can cause esophageal varices, caput medusae, and hemorrhoids.

Caput medusae (dilated umbilical veins)

This can also occur in the oesophagus, causing oesophageal varices, and at the level of the umbilicus, causing caput medusae.

Stigmata of portal hypertension include those of chronic liver disease: ascites, esophageal varices, spider nevi, caput medusae, and palmar erythema.

Portacaval anastomoses: Esophageal varices, gastric varices, anorectal varices (not to be confused with hemorrhoids), and caput medusae.

These lesions appear either as enhancing linear blood vessels or caput medusae, a radial orientation of small vessels that resemble the hair of Medusa from Greek mythology.

Portacaval anastomosis, by contrast, is an anastomosis between a vein of the portal circulation and a vein of the systemic circulation, which allows blood to bypass the liver in patients with portal hypertension, often resulting in hemorrhoids, esophageal varices, or caput medusae.
