Episode notes
Transfemoral Origin Story
- Dr. Jacob Cynamon recounts adopting the transfemoral approach after performing a liver biopsy through a femoral vein.
- This led to abandoning the transjugular approach due to its perceived unnecessary route through the heart.
Transfemoral Success
- A 2016 publication documented 87% of liver biopsies performed using the transfemoral approach.
- A later study comparing transjugular and transfemoral methods revealed similar success rates but fewer complications in the transfemoral group.
Hepatic Vein Confirmation
- Use lateral views to confirm hepatic vein location during transjugular biopsies.
- This is crucial for determining needle direction, unlike in transfemoral procedures where any hepatic vein can be used for pressure measurement.
