Antegrade femoral artery puncture

To determine the optimal site for antegrade puncture of the femoral artery, the authors evaluated three
cadaver specimens and computed tomographic (CT) scans of 50 patients.The relationships among the
common femoral artery, the femoral artery bifurcation, the center of the femoral head, and the inguinal ligament were evaluated. CT showed that the center of the femoral head was always located caudal to the level of the inguinal ligament but cranial to the bifurcation of the common femoral artery. Therefore,the femoral head seems to provide a reliable landmark for entering the
common femoral artery.
