Abstract：
PURPOSE:Within five years after presentation 50-60% of patients with chronic limb-threatening ischemia (CLI) have died or had an amputation. We assessed the predictive value of lower extremity arterial calcification on computed tomography (CT) characteristics on both 7-years amputation-free survival and 10-years all-cause mortality in patients with CLI. METHOD:Included were 89 CLI patients (mean age 73.1 ± 11.6 years) who underwent a CT angiography of the lower extremities. In the femoropopliteal and crural arteries based on a CT score the following calcification characteristics were assessed: severity, annularity, thickness and continuity. The predictive value of different arterial calcification characteristics was analysed by age- and sex-adjusted multivariate Cox regression analysis. RESULTS:Complete annular calcifications were common (femoropopliteal 43.7%, n = 38; crural, 63.2%, n = 55). Mean survival was 278.4 weeks (95% CI 238.77-318.0 weeks). Patients with complete annular calcifications had a higher all-cause 10-year mortality (femoropopliteal unadjusted HR 1.64, p = 0.04 and adjusted for age and sex HR 1.68, p = 0.04; crural unadjusted HR 1.92, p = 0.02, adjusted for age and sex HR 2.29, p = 0.006) than patients with other calcification characteristics. CONCLUSIONS:Annularity of calcification of both femoropopliteal and crural arteries is a predictor for 10-year all-cause survival, its hazard being even higher than the traditional prognostic risk factors for CLI and therefore could be involved in the poor survival of these patients.
