Retrograde tibial angioplasty is a procedure used to treat blockages or narrowing in the tibial arteries by accessing them through the veins. During the procedure, a catheter is inserted into the veins and directed towards the tibial arteries, where balloon angioplasty is performed to open the arteries and restore normal blood flow.

This procedure is highly effective for patients with peripheral artery disease or chronic limb ischemia, offering a less invasive alternative to traditional surgical methods for restoring blood circulation to the lower leg and foot.
