“…This may be partly because ABI was not accurately measured due to calcification, particularly Monckebergʼs calcification in the patients with hemodialysis, many of whom in the F4 group. 15) Although SPP is now widely used for assessing the severity of PAD, particularly in CLI, 16) no correlation with PI was observed in the present analysis. The main reasons for this were that the number of patients in whom both SPP and PI were measured was small, and that most of the patients in whom SPP was measured belonged to the F4 group in whom the PI value was 0 in many patients.…”

Objective : The perfusion index (PI) is a physiological marker for evaluating the peripheral circulation. We explored the possibility of using PI as a screening tool for development of critical limb ischemia in peripheral artery disease (PAD). Method : We measured the PI in 79 limbs of 70 PAD patients. Data were analyzed to find a correlation between the PI and PAD severity. Result : The PI tended to be lower as PAD became severer. Especially, there were significant differences between the Fontaine 1 and Fontaine 4 groups in average PI and minimum PI, and between Fontaine 1 and two other groups (Fontaine 2 and Fontaine 4 groups) in maximum PI. A mild correlation was found between PI and the ankle brachial index. These data were used to calculate an average PI of 0.27 as a cut-off value for critical limb ischemia (CLI). In 65 asymptomatic PAD patients and claudication, significantly more patients with a PI value greater than the cut-off value developed CLI than those with a PI lower than the cut-off. Conclusion : The PI can be a useful tool for evaluating the development of CLI in mild PAD patients, and patients tended not to progress to CLI when their average PI was higher than 0.27.
