What does the abbreviation BCS stand for?

When Budd-Chiari syndrome (BCS) is a closure of laxative large hepatic vein. If left untreated, BCS is extremely painful and leads to liver failure. BCS is very rare, with several small hepatic veins occluded more often. However, the BCS is strictly differentiated from this finding.

What is Budd-Chiari Syndrome?

The Budd-Chiari Syndrome (BCS according to AbbreviatonFinder) is a complete occlusion of the large hepatic vein. BCS can be acute or chronic. In acute BCS, occlusion occurs suddenly and leads to a rapidly deteriorating patient condition.

In the case of a chronic course, the outflow of blood via the large hepatic vein is permanently impaired. The occlusion of the vein leads to blood congestion in the liver. This causes the liver to become abnormally “bloated” and as a result the liver can no longer fulfill its functions. If the BCS is left untreated, it will lead to liver failure.


There are essentially three possible causes for a BCS. Most often there is a thrombosis – i.e. a blood clot – in the large vein, which ultimately leads to an occlusion.

In addition, a liver tumor can be the cause, which – if it is unfavorable and has reached a certain size – can occlude the vein.

Sometimes it happens that a tumor surrounds the vein from the outside and thus compresses the vein. Another possible cause of BCS is inflammation of the liver, such as chronic or acute hepatitis.

Symptoms, ailments & signs

In the worst case, the Budd-Chiari syndrome can lead to the death of the person concerned. Typically, this occurs when the syndrome is left untreated. Those affected primarily suffer from very severe pain in the lower part of the abdomen. There is a strong feeling of pressure in the upper abdominal area.

As a result, the quality of life of the person affected is considerably reduced and restricted. The Budd-Chiari syndrome also leads to the development of ascites. The spleen and liver also enlarge as the disease progresses, which can lead to severe pain. If there is no treatment, the result is nausea, diarrhea and vomiting.

The water retention in the abdomen can also be associated with severe pain. Subsequent liver failure eventually causes the affected person to die of Budd-Chiari syndrome. The severe pain can also lead to a loss of consciousness or even to a coma.

It cannot be predicted whether the person affected will wake up again. The Budd-Chiari syndrome often leads to severe psychological complaints in the patient or in the relatives of the person concerned, so that they are dependent on psychological treatment.

Diagnosis & course

Based on the typical course of BCS or an impending liver failure, a doctor can make a corresponding diagnosis quickly and precisely. He will ask the patient about possible causes (e.g. the presence of an inflammation) and palpate the abdomen. If the suspicion of BCS is confirmed, the doctor will perform a sonography (ultrasound examination) and – if necessary – get a more detailed picture of the occlusive foci by means of liver venography.

Acute BCS is very painful. Almost immediately after the vein is closed, severe pain occurs in the area of ​​the right upper abdomen, often accompanied by a strong feeling of pressure throughout the abdomen. Vomiting and severe nausea are also side effects. Later on, water may be retained in the abdomen (ascites).

The condition of a patient with acute BCS worsens dramatically within a short period of time. The condition can lead to a coma and is often life-threatening. The doctor speaks of a chronic outflow disorder when the blood outflow via the hepatic vein is permanently impaired but not completely interrupted or occurs constantly.

The consequence of chronic BCS is usually a pathologically enlarged liver, which leads to cirrhosis of the liver.

When should you go to the doctor?

In the event of severe abdominal pain and other signs that indicate a serious disease of the internal organs, a doctor must be consulted immediately. Budd-Chiari syndrome worsens rapidly, so prompt treatment is vital. A doctor’s visit is necessary at the latest when water retention in the abdomen is added to the typical symptoms. If the person concerned falls into a coma, the emergency doctor must be alerted immediately.

Even violent vomiting and severe pain are best treated by the emergency services. Patients with chronic or acute hepatitis or liver inflammation are particularly at risk. People who suffer from thrombosis or other diseases of the blood vessels and veins, or who have a liver tumor, should see their doctor at the first symptoms.

Further contact persons are specialists for internal medicine or a specialist for venous diseases. After the diagnosis, it may be necessary to go to a specialist clinic where a liver transplant is performed. Due to the risk of relapse, regular check-ups with the responsible doctor are indicated after treatment.

Treatment & Therapy

To restore optimal blood flow through the large hepatic vein, the doctor will first try to resolve the thrombosis with medication (thrombolysis) if BCS is present.

If this does not succeed, the insertion of a shunt can be considered. A shunt is used – in very simplified terms – to bypass the occlusive focus by means of a “diversion”. There is also the option of removing the closure using a surgical technique that is specially tailored to the particular situation. If BCS is chronic, i.e. if the large hepatic vein is blocked frequently, the liver is permanently damaged.

To prevent this, the doctor will prescribe a drug to prevent blood clotting (such as Marcumar). If this does not work, or if a patient suffers from the side effects of the medication over the long term, a liver transplant may be indicated.

Outlook & forecast

Budd-Chiari syndrome must be treated in any case. This disease does not heal itself and the person concerned will continue to die if treatment is not initiated. Usually the patient then dies due to liver failure.

The syndrome is also associated with very severe pain if there is no treatment. During treatment, medication is primarily administered to alleviate the symptoms. However, if these show no effect, the patient has to rely on a shunt to alleviate the symptoms.

If the disease is chronic, the liver is irreversibly damaged and the patient dies. After all, a liver transplant is necessary to keep the person affected. However, this can also lead to severe side effects and various complications, so that a general course of the disease cannot be given.

In many cases, however, the prognosis for Budd-Chiari syndrome is relatively poor, which means that life expectancy is reduced. An early diagnosis of Budd-Chiari syndrome always has a positive effect on the further course of the disease.


A BCS can only be prevented to a limited extent. Patients who are prone to developing BCS due to a previous illness – such as a tendency to thrombosis, a tumor or hepatitis – should have regular check-ups.

If there is a risk of developing chronic BCS, prophylactic use of an anti-coagulant can be considered. It is also advisable not to put unnecessary strain on the liver, for example through excessive consumption of alcohol or medication.


Follow-up care is only possible in rare cases with Budd-Chiari syndrome. The disease is primarily treated with medication so that it must be taken regularly. Possible interactions with other drugs should also be checked and discussed with a doctor.

If the drug treatment does not bring the desired success, the Budd-Chiari syndrome must be treated with a surgical procedure. In some cases, however, the affected person’s liver is already so badly damaged that the patient will die if a transplant cannot be performed.

After a transplant, the liver must be monitored continuously to avoid complications. The patient has to be prepared for a longer stay in a hospital. Wound healing must also be promoted. Unnecessary exertion or sporting activities should be avoided. The patient must follow a healthy lifestyle with a healthy diet.

Alcohol and nicotine should be completely avoided. In most cases, the patient’s life expectancy is significantly reduced despite treatment for Budd-Chiari syndrome. Even after successful treatment, the patient is dependent on taking medication and regular medical examinations.

You can do that yourself

People diagnosed with Budd-Chiari Syndrome need extensive medical treatment in the first place. Medical therapy can be supported by various self-help measures and the use of alternative means from naturopathy.

First of all, the person concerned should pay attention to strict personal hygiene. Since shunts are usually set in Budd-Chiari syndrome, there is an increased risk of infection. Regular washing is all the more important, especially in the affected area. Moderate outdoor exercise and a healthy diet can further aid recovery.

If the affected area shows signs of inflammation, the doctor must be informed immediately. The doctor will usually recommend rest and bed rest to the patient. Sufficient rest is particularly important in the first few weeks and months, as the disease can put a heavy strain on the body and mind.

In order to avoid emotional complaints, a therapist should be consulted during physical treatment. Patients who feel depressed or have unusual mood swings as a result of the illness are best advised to speak to their doctor. Often the symptoms can be alleviated by changing the medication, but in some cases further treatment by a therapist or psychotherapist is indicated.
