WHY THE STUDY WAS PERFORMED: Whilst it is standard practice to image the three-vessel run-off at the ankle, sonographers tend to stop scanning at the ankle. There is also have a poor understanding of pedal arterial anatomy and how it collateralises when disease is present. With the advances in ultrasound technology, it is now possible to comprehensively evaluate the haemodynamic flow in the pedal arterial system. This is important as it gives an understanding of the perfusion in this region, which will help with the prediction of wound healing in the foot and can aid in interventional planning.
HOW THE STUDY WAS PERFORMED: The paper begins by going over the arterial anatomy at the foot on both the dorsal and the plantar aspect and how these vessels branch to perfuse the toes. This is demonstrated in diagram 1 below.
It also covers important collateral pathways from the peroneal artery at the ankle; • Posterior Communicating Artery (PCA) and the Lateral Calcaneal Branch (LCB) both communicate from the Peroneal Artery to the Posterior Tibial Artery • The Anterior Communicating Artery (ACA) communicates from the Peroneal Artery to the Anterior Tibial Artery (ATA) The paper goes on to describe a 12 month retrospective review that was performed on thirty patients with peripheral vascular disease. This was to evaluate the changes in haemodynamic flow in the foot with ultrasound when different areas of occlusion were present.
