What size needle is used for a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure?

From the Guidelines

Needle Size for TIPS Procedure

The needle size used for the initial puncture in a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure is typically a 21-gauge or 22-gauge needle 1.

• This is followed by the introduction of a guidewire, which facilitates the subsequent steps of the procedure.
• The use of a covered stent with a diameter of 8–10 mm and an average final dilation of 7–8 mm is commonly recommended for TIPS placement 1.
• It's worth noting that the technical challenges in TIPS procedures, especially in children, may require particular attention to the type of equipment used, including the needle size and the stent diameter 1.
• The choice of needle size and equipment should be based on a thorough assessment of the patient's anatomy and the technical feasibility of the procedure, taking into account factors such as the patient's age, size, and vascular anatomy 1.

From the Research

Needle Size for TIPS Procedure

The provided studies do not directly mention the size of the needle used for a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure.

TIPS Procedure Details

• The TIPS procedure is used to manage complications of portal hypertension, including acute variceal hemorrhage, prevention of recurrent variceal bleeding, and refractory ascites 2, 3, 4.
• The procedure involves the placement of a shunt in the liver, which can be done with a low risk of mortality 2.
• The use of polytetrafluoroethylene-covered stents has improved shunt patency and outcomes 3.
• The procedure can be used as a bridge to liver transplantation in properly selected candidates 5.

Shunt Diameter

• Studies have compared the results of TIPS placement with 10-mm and 12-mm Wallstents, with the 10-mm group showing better short- and long-term results 6.
• The use of smaller diameter TIPS is discussed as a possible way to prevent post-procedural complications 4.
