case_images: Baseline angiography revealed non-significant lesions in the superficial femoral and popliteal arteries and total occlusion of the distal segment of the popliteal artery along with the proximal portions of the three distal run-off vessels while demonstrating distal flow in the dorsalis pedis artery from collaterals (Fig. 1).
case_images: Intravenous cannula at the dorsum of the foot (a) and guidewire inside the dorsalis pedis artery (b).

case_images: The dorsalis pedis artery was punctured at the dorsum of the foot with a 20-gauge IV cannula (cannula-over-needle device with internal diameter of 0.8 mm and length of 32 mm) under fluoroscopic guidance (Fig. 2a). Next, a 0.014-inch hydrophilic guidewire was inserted into the cannula and advanced through the lumen retrogradely (Fig. 2b).
case_images: Entrance of the guidewire into the guiding catheter.

case_images: At that time, we were able to enter into the guiding catheter with the guidewire following successful guidewire passage via the tibialis anterior artery (Fig. 3).

case_images: Final angiography demonstrated that antegrade flow was restored with well-visualized anterior tibial and dorsalis pedis arteries (Fig. 4a and b).
