How To Do Femoral Vein Cannulation, Ultrasound Guided
Introduction
Ultrasound-guided cannulation of the femoral vein uses real-time (dynamic) ultrasound to guide venipuncture and a guidewire (Seldinger) technique to thread a central venous catheter through the femoral vein and into the inferior vena cava. Femoral venous cannulation has the procedural advantages of a relatively superficial and easily accessed vein as well as nearby anatomy that lacks the complexity and vital structures of the jugular and subclavian regions. However, femoral central venous catheters (CVCs) have higher risks of infection and thrombosis and are appropriate only for bedridden patients. Ultrasound guidance for placement of femoral lines increases the likelihood of successful cannulation and reduces the risk of complications. When ultrasound guidance and trained personnel are available, this method of placement is preferred. (See also Central Venous Catheterization ,
