Caput Medusae: Causes, Symptoms and Treatment

Caput Medusa is a very important clinical sign appearing on a patient when the paraumbilical veins become prominent, distended, and engorged and radiate from the umbilicus across the abdomen. This could be a sign of underlying portal hypertension, mostly related to serious liver conditions like cirrhosis.

What Causes Caput Medusa?

Portal hypertension comes first in the list of causes, which is an increase in the pressure within the portal venous system. According to Dr Richard Thompson, a hepatologist at St. Mary's Hospital, "Portal hypertension is most commonly due to liver cirrhosis, but it can also result from other conditions such as portal vein thrombosis or schistosomiasis." In turn, liver cirrhosis is often caused by chronic alcohol abuse, hepatitis B and C, and fatty liver disease or non-alcoholic fatty liver disease.

What are the Symptoms of Caput Medusa?

Though Caput Medusae itself is a visible symptom, it is often accompanied by other symptoms of portal hypertension. The patient may have variceal bleeding, splenomegaly, and ascites. In fact, a Journal of Hepatology article concludes, "Approximately 70% of patients with liver cirrhosis have some signs of portal hypertension; Caput Medusae is considered an advanced presentation of this symptom."

What is the Diagnosis of Caput Medusa?

Diagnosis of Caput Medusae is usually conducted with a physical examination, accompanied by imaging studies. Ultrasound and Doppler studies are aspects of the assessment for the portal venous system. According to radiologist Dr Emily Clarke, "These imaging modalities help to determine the extent of the venous distension and if portal hypertension is present, which aids in the correct diagnosis for Caput Medusae."

What is the Treatment for Caput Medusa?

Treatment for Caput Medusae is focused on treating the cause of portal hypertension. This consists of medical management of liver disease through antiviral therapies for hepatitis or lifestyle modification in NAFLD. In fact, some would even require surgical interventions like TIPS to reduce portal pressure. A study published in the Journal of Clinical Gastroenterology in 2019 states, "TIPS has shown a 60-70% success rate in alleviating symptoms associated with portal hypertension, including Caput Medusae."

What is the Prognosis of Caput Medusa?

The prognosis for patients with Caput Medusae largely depends on the severity of the underlying liver disease. If liver conditions are identified and treated at an early stage, then prognosis can be significantly improved. Dr Alan Roberts, a gastroenterologist, comments, "Early intervention in the cases of liver cirrhosis can prevent progression toward severe portal hypertension and the development of complications such as Caput Medusae."
