Abstract
Purpose: To determine the optimal skin site for retrograde common femoral arterial puncture based on the inguinal skin crease. Materials and Methods: We retrospectively evaluated CT arteriographic images of right groins in 200 patients. We measured the relative distances of the common femoral artery bifurcation and inguinal ligament from the inguinal skin crease, respectively. We calculated the rates of common femoral artery puncture at 1 mm intervals, above or below the inguinal skin crease. Results: The range in skin site where the rates of common femoral artery puncture were greater than 60%, 70%, and 80% were situated between 3 mm below to 27 mm above, 1 mm to 23 mm above, and 5 mm to 15 mm above the inguinal skin crease, respectively. The skin site of the highest puncture rate was 10 mm above inguinal skin crease (85.2%). Conclusion: The optimal skin site for retrograde common femoral artery puncture was above the inguinal skin crease, most optimally at 10 mm above the inguinal skin crease.
