The anatomic relationship between the common femoral artery and common femoral vein in frog leg position versus straight leg position in pediatric patients.

Background: Overlap of the femoral artery (FA) on the femoral vein (FV) has been shown to occur in pediatric patients. This overlap may increase complications such as arterial puncture and failed insertions of central venous lines (CVLs). Knowledge of the anatomic relationship between the FV and FA may be important in avoiding these complications.
