Critical limb-threatening ischaemia and microvascular transformation: clinical implications
Authors' conclusion
These findings depict a progressive, hypoxia-driven transformation of the microvasculature in CLTI muscles, which pathologically alters blood flow dynamics and aggravates tissue damage under low arterial driving pressure.
