Key result
Blood obtained via ultrasound-guided cannulation of the saphenous vein showed no creatinine release (100.5% of arterialized blood) compared to forearm muscle drainage (121%).
Absolute Event Rate: 100.5% vs 121%
The described ultrasound-guided cannulation technique successfully isolates femoral adipose tissue venous drainage, facilitating future physiological studies of lower-body fat depots in humans.

Ultrasound-guided saphenous cannulation isolates adipose-specific venous blood; extends tools for lower-body fat research but leaves clinical translation open.
McQuaid et al. (2010) studied this question. Cannulation of a vein draining the femoral fat depot vs. Blood from forearm muscle and subcutaneous abdominal adipose tissue was evaluated on Creatinine concentration relative to arterialized blood. Blood obtained via ultrasound-guided cannulation of the saphenous vein showed no creatinine release (100.5% of arterialized blood) compared to forearm muscle drainage (121%).
