We moved to the toe pressure precisely because digital arteries were supposed to be spared from calcification. A new JVS-Vascular Insights study from Welling, Bakker, Ferraresi and colleagues finds digital artery calcification in nearly 30% of limbs, shows it doubles one-year limb-event risk, and that it falsely elevates toe pressure — with a simple fix: when calcium shows on the foot film, subtract 20–30 mmHg.
We Moved to the Toe to Escape Calcification — and It Followed Us There: Digital Artery Calcification, Falsely-High Toe Pressures, and a 20–30 mmHg Temporary Fix #DiabeticFoot #PAD #CLTI #ToePressure #Calcification #LimbPreservation #ActAgainstAmputation @alpslimb
