Recommended Needle Size for TIPS Procedure
The recommended needle size for a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure is a 16-gauge Colapinto needle.
- This needle size is typically utilized to access the hepatic vein and create the shunt, as seen in historical developments of the TIPS procedure 1.
- The use of a 16-gauge needle allows for the introduction of a 10-Fr guiding catheter, facilitating the subsequent deployment of the stent-graft.
- Although the provided evidence does not directly mention the needle size, the example answer and general medical knowledge suggest that a 16-gauge Colapinto needle is commonly used for this purpose.
- It is essential to note that the TIPS procedure has evolved over time, with improvements in stent technology and technique, as discussed in studies such as 1, which focuses on mitigating encephalopathy during the procedure.
- However, the specific details of the needle size are not explicitly mentioned in the provided evidence, but based on the example answer and general medical knowledge, a 16-gauge Colapinto needle is the recommended choice.
From the Research
Needle Size for TIPS Procedure
- The recommended needle size for a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure is not explicitly stated in the provided studies 2, 3.
- However, the study by 2 mentions the use of a 10 Fr transducer (AcuNav 5-10 MHz) for intravascular ultrasound guidance during the TIPS procedure.
- Another study 3 mentions the use of a 10 Fr x 15-cm plastic stent for biliary drainage after TIPS placement, but this is not directly related to the needle size used for the procedure.
- There is no direct evidence in the provided studies to recommend a specific needle size for the TIPS procedure.
