Abstract
Segmental systolic pressures were measured in a group of patients with clinically irreversible ischemia. There was a good relationship between the level of pressure in a limb and the eventual outcome, but a particular level of pressure was found to be a poor indicator of a specific level of viability. These results support previous concern about the limitations of systolic pressure measurements in determining the level of limb viability. We suggest that local intrinsic regulation of the microcirculation plays a major role in the ultimate survival of tissues in an ischemic limb.
