We here report a successful angioplasty for tibial artery occlusion using direct tibial puncture and subsequent retrograde approach under surgical cutdown technique. An 82-year-old man with ulcer/gangrene in first and second digits was referred to our hospital for endovascular therapy (EVT) of lower extremity ischemia. Diagnostic angiogram revealed anterior tibial artery (ATA) occlusion with severe calcification. Subintimal angioplasty was attempted using a 0.014-inch hydrophilic guidewire but was unsuccessful. A retrograde approach was subsequently attempted for ATA recanalization. However, because of severe calcification of dorsal pedis artery (DPA), percutaneous distal puncture was also unsuccessful. Direct puncture under surgical cutdown technique for DPA was subsequently performed and was successful. A 0.014-inch hydrophilic wire was advanced in retrograde fashion across the ATA occlusion and was used to access the microcatheter positioned at the proximal ATA via antegrade approach. Angioplasty of the ATA occlusion was performed using a 2.5-/3.0-mm tapered balloon. Completion angiogram revealed restoration of flow without dissection. Skin perfusion pressure was dramatically improved. Complete wound healing was achieved 5 months after EVT.
