case_images: Ultrasound examination showing common carotid artery occlusion with patent distal vessels. Anterograde flow in both the ICA and ECA. (a) Colour mode examination: no flow in the left common carotid artery (LCCA), and the vessel lumen is filled with thrombotic material. (b) Duplex mode examination: anterograde flow in the left internal carotid artery with a steal effect, deceleration, and inversed flow in mesosystole. (c) Duplex mode examination: anterograde flow in the left external carotid artery. (d) Duplex mode examination: retrograde flow in the left superior thyroid artery. (e) Colour mode examination: retrograde flow in the left superior thyroid artery and anterograde flow in LECA.

case_images: Willis via the anterior and posterior communicating arteries. We did not find any data similar to our case (Figure 2) in the literature where both the ICA and ECA had anterograde flow and were supplied through a major branch of the ECA with retrograde flow.
