Note on variability of the arteries of the lower extremities in man.
The organization of the arterial bed was evaluated in the arteriograms of 253 lower extremities of subjects of a known sex and age. High origination of the a. profunda femoris from the a. iliaca ext. was observed in 0.4% of the cases; in 0.8% the a. profunda femoris arose from the transition of the a. iliaca ext. to the femoral artery. The crural segment was the most variable part of the arterial bed of the lower limbs. Most frequently, in 21.7% of the subjects, anomalies of the crural arteries were unilateral; in 4.6% they were bilateral. In 2.3%, bilaterally different anomalies were present. The a. tibialis post. is the most variable crural artery and the a. peronea is the most stable.
