Artificial liver transplantation is an important method for treating liver failure, which restores liver function by transplanting healthy liver tissue or artificial liver organs into the patient's body. Although artificial liver transplantation has become an important breakthrough in modern medicine, it is still a high-risk surgery that requires patients to undergo regular examinations and monitoring to ensure their physical health. Ultrasonic scanner, as a commonly used imaging tool, plays a very important role in the diagnosis of artificial liver transplantation. This article will provide a detailed introduction to the necessity and application of ultrasound scanners after artificial liver transplantation.

1、 Common complications of artificial liver transplantation

Although artificial liver transplantation is an efficient treatment method, there are also certain risks and complications that require timely detection and treatment to ensure the health of patients. The following are common complications of artificial liver transplantation:

Graft rejection: Due to changes in the immune system after artificial liver transplantation, patients may experience graft rejection, manifested as symptoms such as fever, fatigue, nausea, and vomiting.

Vascular complications: Bleeding and vascular embolism within 7 days after artificial liver transplantation are common complications that may lead to graft necrosis.

Infection: due to the impaired immune function after surgery, patients are prone to infection, such as liver, lung, urinary system and other organ infections.

Graft dysfunction: It may lead to symptoms such as jaundice, cholestasis, and neonatal hepatitis.

Others: including surgical wound infection, hepatic artery stenosis, deep vein thrombosis, etc.

Due to the presence of these complications and risks after artificial liver transplantation, it is necessary to conduct regular examinations and monitoring of patients in order to promptly identify problems and take measures.

2、 Application of ultrasound scanner after artificial liver transplantation

Ultrasonic scanner, as a very common imaging examination tool, plays a very important role in the diagnosis of artificial liver transplantation. The following are the applications of ultrasound scanners after artificial liver transplantation:

Graft rejection detection: Ultrasonic scanners can detect the size, shape, and blood flow of the graft to determine whether there is rejection.

Detection of vascular complications: Ultrasound scanners can detect situations such as vascular embolism or bleeding, helping doctors take timely measures to avoid possible risks.

Infection detection: ultrasonic scanner can detect the pathological changes of liver, lung, urinary system and other organs, and assist doctors in diagnosis and treatment.

Graft dysfunction detection: Ultrasonic scanners can detect whether the function of the graft is normal, such as the presence of jaundice, cholestasis, and other conditions.

In addition to the above applications, ultrasound scanners can also help doctors diagnose other possible problems, such as surgical wound infection, hepatic artery stenosis, and deep vein thrombosis. In addition, ultrasound scanners have the characteristics of non-invasive, radiation free, and easy operation for patients, making them very suitable for use in the examination after artificial liver transplantation.

3、 Preparation of ultrasound scanner before artificial liver transplantation

Before conducting ultrasonic scanning inspection, some preparatory work needs to be done to ensure the accuracy and reliability of the inspection results.

Patients need to eat on an empty stomach: Do not eat for 6 hours before the examination to avoid food affecting the liver.

The patient needs to empty the bladder: because the bladder will block the vision of the examining organ, it needs to empty or use a catheter.

Patients need to remove tight clothing: Tight clothing can affect the visual field of the examination organ, so it needs to be removed.

Patient needs to be in a semi recumbent position: The patient needs to maintain a semi recumbent position for examination by the doctor.

4、 Precautions for ultrasound scanner after artificial liver transplantation

There are also some issues that require special attention when performing ultrasound scanning after artificial liver transplantation.

Avoid applying pressure to the surgical site: As the surgical site may not have fully healed, it is necessary to avoid applying pressure to it.

Ensure equipment and probe cleanliness: The probe of the ultrasound scanner needs to be cleaned and disinfected to avoid cross infection and other issues.

Pay attention to the patient's comfort level: During the examination, it is necessary to pay attention to the patient's comfort level and promptly inquire if they have any discomfort symptoms.

Provide appropriate support: Some patients may require additional support, such as pillows or cushions, to maintain a comfortable posture.

In summary, ultrasound scanners have very important application value in the diagnosis of artificial liver transplantation, which can help doctors discover potential problems in patients in a timely manner and take corresponding measures. Therefore, in regular examinations after artificial liver transplantation, ultrasound scanners are a necessary imaging tool that helps to protect the health and safety of patients.
