The MAC score told Mariano everything he needed to know before he touched the wire. 72-year-old, diabetic, Rutherford 6, right foot with gangrene of the first and fifth toes and plantar involvement. Three surgeons had already opened the foot surgically, found nothing usable, and referred for BKA. Mariano's team ran a CO2 angiogram, found the plantar circulation was fed by a peroneal posterior branch (anatomical variation nobody had imaged), and then he did something that looks reckless if you don't understand the logic behind it. He went subintimal. Aggressively. Recanalized the peroneal in about two minutes with an 0.35 NaviCross and a half-stiff J-tip Terumo wire. Pushed the catheter with the wire rather than just advancing the wire alone. Controlled the loop, used the tip, not the stiff part. Same wire, same technique to navigate the lateral plantar once he entered the foot through the posterior branch. Why was he comfortable being that aggressive? Because the MAC score was low. His line: "No calcium is in high percentage a big synonym of subintimal and fast cross." That one sentence reframes the entire decision tree. Low MAC means subintimal dissection is forgiving. You can move fast, you can loop, you can push. High MAC changes everything. You'd need to stay intraluminal because subintimal dissection in heavily calcified tibials is brutal, and in calcified foot arteries it's close to impossible. So the calcification score isn't just a descriptor on the chart. It's the variable that determines whether you're doing a two-minute recanalization or a completely different procedure. And then the part that stuck with me. As Mariano navigated deeper into the foot, he started finding vasculature nobody expected. A hibernated lateral plantar. The arch communicating to dorsal circulation. Fourth and fifth metatarsal arteries lighting up. Miguel made the point that no pre-operative image would have shown any of this. You don't get a blueprint before you go in. You get breadcrumbs. Each step of the procedure reveals the next clue, and you follow it. That's the part I think most trainees don't hear enough. The plan isn't supposed to be perfect before you start. The plan builds itself as you move, if you know what to look for and you have the technical vocabulary to follow where it leads. Mariano found the distal distribution system, saw the arch connect, and said: "Now I have a lot of hope because I have a distal distribution system, so I know I can make it function." Three months later the patient healed. Walking. Limb saved with a transmetatarsal amputation. The MAC score gave him permission to be aggressive. The technique gave him access. And the willingness to follow breadcrumbs instead of demanding a perfect map gave the patient a foot.

Most vascular labs only reach for CO2 angiography when the creatinine is already ugly. Mariano Palena has been using it as his default for over 15 years. Not as a backup. Not as a last resort for the patient with a GFR of 18. As standard of care, even in patients with normal kidneys. That reframing changed how I think about contrast use in diabetic CLTI. Here's what we typically do: we reach for iodinated contrast because it's familiar, the images are beautiful, and CO2 feels like a compromise. Meanwhile we're burning through expensive contrast (Visipaque for diabetics isn't cheap) and stacking nephrotoxic risk on patients who already have kidneys hanging by a thread. Mariano's approach cuts iodine use by at least 50%. And with proper technique, bending the foot to eliminate movement artifact, using nerve blocks so the patient isn't flinching, the CO2 images are genuinely diagnostic. In the case we reviewed together, the CO2 angiogram is what revealed a plantar circulation fed by a peroneal posterior branch that three surgeons had missed on open surgical exploration. That anatomical finding is what saved the leg. The economics are hard to ignore too. CO2 is significantly cheaper per case than premium iodinated contrast. Multiply that across every diabetic CLTI patient in a busy cath lab and the numbers add up fast. Miguel said something honest during our conversation: he only reaches for CO2 when a patient has bad CKD. And I think that's where most of us are. We treat it like a workaround instead of a first-line tool. The question I keep sitting with is simple. If CO2 reduces nephrotoxicity, costs less, and in the right hands produces images good enough to catch what open exploration missed, why is it still the backup plan?

A 72-year-old man was sent for a major amputation. One angiogram exposed the anatomy everyone else had missed—and a path to save his limb. Dr. Mariano Palena is an interventional radiologist and vascular specialist focused on complex endovascular limb salvage and chronic limb-threatening ischemia. In this Case Cast, he joins Dr. Lucas Ferrer and Dr. Miguel Montero-Baker to reconstruct a rescue that began after failed surgical revascularization and ended with a healed foot. The patient had diabetes, ischemic heart disease, bilateral CLTI, a previous left transmetatarsal amputation, and extensive gangrene of the right forefoot. A prior team explored possible bypass targets and concluded that nothing more could be done. Mariano’s team challenged that conclusion with a rule every limb-salvage program should confront: no major amputation without angiography. In this conversation, Dr. Mariano Palena reveals: ⬛ Why a foot that looks like a vascular “desert” may still contain hibernating vessels—and the clues that reveal them. ⬛ How an anatomical variation in the plantar circulation can make a reasonable bypass strategy fail before the true target is recognized. ⬛ Why telling patients that bypass is “one and done” creates the wrong expectations for a chronic disease that may require repeat maintenance. ⬛ What changes when clinicians describe limb salvage as remission rather than cure—and why another intervention may still be a successful outcome. ⬛ How Mariano follows angiographic “breadcrumbs,” crosses long chronic total occlusions, re-enters plantar vessels, and rebuilds flow through the foot. ⬛ Why the team debated opening one tibial pathway versus two—and whether extra flow justified more time, contrast, radiation, and devices. ⬛ What happened after the final angiographic “wow” moment: reconstruction, complete healing at three months, and a return to work. This is not a promise that every threatened limb can be saved. It is a close look at the reasoning, imaging, technical persistence, and honest patient counseling required before an irreversible decision is safely made.
