When suffering from chronic liver disease, especially liver cirrhosis, patches of blood or red spots and plaques appear on the thenar skin of thumb and little finger, which turn white after compression and red soon after release. This palm, which is different from normal people, is called the liver palm. Most patients with liver cirrhosis will have liver palms.
How is the liver palm formed? In fact, the cause of liver palm is the same as spider nevus, mainly because of liver cirrhosis, and the metabolic inactivation function of liver palm is damaged to varying degrees, which accumulates in the body, stimulates the congestion and expansion of capillary arteries, and forms liver palm over time.
It should be noted that liver disease does not always appear in the liver palm, because some healthy people also have liver palms in clinic, but after years of observation, liver function has been normal and liver disease has never appeared. It can be seen that the liver palm has no specificity and cannot be used as the diagnostic standard of liver disease. Therefore, for patients with liver palm, it is necessary to combine medical history, physical examination, liver function, hepatitis B virus surface antigen, B-ultrasound, scanning and other examinations to make a comprehensive analysis and judgment, so as to make a correct conclusion.
