CT Guided Random Liver Biopsy
HISTORY:
CT DOSE:
SEDATION: Monitored by the IR registered nurse or surrogate, an independent trained observer providing Moderate Sedation with fentanyl.
CONSENT: Following discussion procedure its risks benefits (including bleeding and vessel damage) and alternatives, review of readily available relevant imaging prior to the procedure informed consent was obtained witnessed and documented upon the chart. Standard presurgical timeout confirming patient procedure and when relevant side and site was performed. Any discrepancies were resolved via consultation with appropriate readily available data sources. The patient was prepared and draped in standard sterile fashion.
TECHNIQUE:
Following explanation of the potential risks and benefits of the procedure, including bleeding and infection and prior to obtaining procedural consent, informed consent was obtained.
Timeout was performed per protocol.
Conscious sedation was provided by certified nursing staff after normal head/neck and cardiopulmonary exam. ASA 2
Procedure was done under sterile technique and local anesthesia using 1 % lidocaine.
The right lobe of the liver was chosen using CT guidance.
17/18 gauge coaxial system was used. 18 gauge core was obtained.
Gel foam was applied for embolization along the biopsy tract using the coax, as the needle was pulled, to decrease the risk of bleeding.
The patient tolerated the procedure well. There were no immediate complications.
IMPRESSION:
Successful CT guided random biopsy of the right liver.
Frequently Asked Questions
What is a CT-guided liver biopsy?
A CT-guided liver biopsy is a procedure where a needle is inserted into the liver to obtain a tissue sample, using CT imaging to precisely guide the needle. This method helps in diagnosing liver conditions by analyzing the tissue sample under a microscope.
The procedure involves using CT imaging to locate the liver and guide the biopsy needle. After obtaining informed consent, the patient is sedated and local anesthesia is applied. A sterile needle is inserted into the liver to collect tissue samples. Gel foam may be used to prevent bleeding along the needle tract.
What are the risks associated with a CT-guided liver biopsy?
Risks include bleeding, infection, and potential damage to surrounding blood vessels. However, these risks are minimized by using sterile techniques and imaging guidance. Patients are monitored closely during and after the procedure to manage any complications.
What should a patient expect after a CT-guided liver biopsy?
After the biopsy, patients are monitored for any immediate complications, like bleeding. Most experience mild pain or soreness at the biopsy site, which typically resolves quickly. Patients should follow their doctor's instructions for post-procedure care and report any unusual symptoms.
Why is CT imaging used during a liver biopsy?
CT imaging provides real-time, detailed images of the liver, which helps in accurately guiding the biopsy needle to the target area. This reduces the risk of complications and increases the likelihood of obtaining a good tissue sample for diagnosis.
What is the role of sedation in a CT-guided liver biopsy?
Moderate sedation, often with medications like fentanyl, is used to help the patient remain comfortable and relaxed during the procedure. It is monitored by trained personnel to ensure patient safety and to minimize discomfort.
How should a patient prepare for a CT-guided liver biopsy?
Patients may be instructed to avoid eating or drinking several hours before the procedure and to discuss any medications with their doctor. It's important to have someone to drive them home afterward due to the effects of sedation.
