Femoral canal ring, through which bowel can sometimes enter, causing a femoral hernia. Though femoral hernias are rare, their passage through the inflexible femoral ring puts them at particular risk of strangulation, giving them surgical priority. The position of the femoral canal medially to the femoral vein is of physiologic importance. The space of the canal allows for the expansion of the femoral vein when venous return from the lower limbs is increased or when increased intra-abdominal pressure (valsalva maneuver) causes a temporary stasis in the venous flow. Femoral canal In human anatomy of the leg, the femoral sheath has three compartments.
Femoral triangle to a major artery, coronary angioplasty and peripheral angioplasty is often performed by entering the femoral artery at the femoral triangle. Heavy bleeding in the leg can be stopped by applying pressure to points in the femoral triangle. Another clinical significance of the femoral triangle is that the femoral artery is positioned at the midinguinal point (midpoint between the pubic symphysis and the anterior superior iliac spine); medial to it lies the femoral vein. Thus the femoral vein, once located, allows for femoral venipuncture.. Femoral venopuncture is useful when there are no superficial veins that can be aspirated in a
