Transjugular Liver Biopsy
Transjugular liver biopsy is typically performed in patients who have a
greater-than-average risk of bleeding complications. It also is employed
in patients where ascites (i.e. fluid in the abdominal cavity) increases the
risk of complications after biopsy. The procedure has been available at most
tertiary care centers for the last decade or two. Typically, the technique for
transjugular liver biopsy entails:
- The patient is positioned upon his or her back on a fluoroscopy (i.e. X-ray)
table in the interventional radiology suite.
- The patient is sedated.
interventional radiologist disinfects and anesthetizes the skin over the right
side of the neck.
- A small incision is made over the right internal jugular vein.
- A catheter is introduced into the right internal jugular vein.
- A guide wire is
placed through the catheter, via the superior and inferior vena cava vessels,
into the right hepatic vein.
- Its correct position is checked using
- A specially designed biopsy catheter system is then introduced over
the guide wire and is positioned in the right hepatic vein.
- The actual biopsy
needle is introduced via this new catheter.
- The biopsy is performed through the
wall of the hepatic vein.
- The catheter is removed.
- The patient is sent to the
