From: Duplication of superficial femoral artery: imaging findings and literature review
Gray scale (a) and color Doppler ultrasonography (b) show that the left superficial femoral artery is divided into two trunks (arrows) with similar luminal diameter and courses parallel. The axial image of arterial phase CTA of bilateral lower extremity (c) shows the duplicated left superficial femoral artery (arrows). The luminal diameter of the medial one is slightly larger than that of the lateral one. Note normal right superficial femoral artery
