The Impact of Calcium Score of femoropopliteal artery after Endovascular treatment (EVT)
Background: The impact of calcium score of coronary artery is widely known, but the impact of calcium score of femoropopliteal artery is still unknown.
Methods: A retrospective analysis was performed with collected data of the lesions treated by EVT for femoropopliteal artery between April 2007 and September 2017. The calcium scores for femoropopliteal artery were calculated with pre-procedural CT according to the Agatston definition. Receiver operating characteristic curve (ROC) revealed the cut off value was 470.We divided the scores into two groups with 470 cut off value. The prognostic value of the calcium score was analyzed based on target lesion revascularization (TLR), major amputation (MA), and any cause death.
Results: A consecutive 171 lesions which underwent successful EVT were analyzed in this study. 72 lesions were divided into the group with calcium score > 470. There were no significant differences between the two groups in the patients and lesion characteristics except hemodialysis. (73% vs 31%, p< 0.01) Procedure time was significantly higher in the group with calcium score > 470. (138 min vs 111 min, p=0.02). Kaplan Meir curve showed TLR was significantly higher in the group with calcium score > 470. (35% vs 10%, p<0.01) There were no significant differences between the two groups in MA and death. Multivariate analysis revealed calcium score > 470 (HR:5.6 95%CI:2.4-13.0, p<0.01) and poor run off (HR:2.2 95%CI: 1.0-5.0, p=0.04) were the predictors of TLR.
Conclusions: The greater calcium score group might make the procedure more complex and increase TLR.
