Abstract
Abstract
Purpose
The aim was to determine the location of the folding point of the arterial ilio-femoral axis and his angulation.
Materials and methods
Forty-five dynamic arteriographies were analyzed and 37 were included in the current study. Different lengths were measured, based on specific anatomical landmarks: the departure of the external iliac artery, the inguinal ligament and the bifurcation of the femoral artery. These lengths were measured in extension and during flexion of the hip in order to determine the folding point.
Results
In extension, some physiological angulations of the external iliac artery were measured.
During flexion of the hip joint, the distance from the folding point to the bifurcation of the common iliac artery was respectively 82 +/- 21 mm (range 48-116) on the right and 95 +/- 20 mm (range 59-132) on the left side. The distance from the folding point to the inguinal ligament was respectively 38 +/- 40 mm (range 12-138) on the right and 26 +/- 23 mm (range 8-136) on the left side. The distance from the folding point to the bifurcation of the femoral artery was respectively 45 +/- 29 mm (range 15-107) on the right and 27 +/- 12 mm (range 10-66) on the left side. During flexion, the angulation of the folding point of the ilio-femoral axis was 114 +/- 18 ° (range 81-136°).
Conclusions
The folding point was located cranially to the inguinal ligament and below the departure of the external iliac artery.
