Abstract:

Objective

To analyze the predictive value of serum intercellular adhesion molecule-1 (ICAM-1) levels for postoperative restenosis in patients with lower extremity arteriosclerosis obliterans (ASO).

Methods

A total of 94 ASO patients admitted between July 2021 and July 2023 were enrolled. Based on the occurrence of restenosis within one year postoperatively, patients were divided into a restenosis group (n=37) and a patency group (n=57). Multivariate logistic regression and interaction analyses were used to evaluate the impact of ICAM-1 and other indicators on restenosis.

Results

Multivariate logistic regression analysis showed that infrapopliteal lesions, diabetes, hyperlipidemia, and elevated preoperative levels of C-reactive protein, interleukin-6, tumor necrosis factor-α, plasma viscosity, whole blood viscosity (high/low shear), and ICAM-1 were independent risk factors for postoperative restenosis (P<0.05). Interaction analysis revealed that preoperative ICAM-1 significantly interacted with endothelin and vascular endothelial growth factor to influence restenosis risk.

Conclusion

ICAM-1 levels are closely correlated with postoperative restenosis in ASO patients and serve as a significant predictor for the risk of re-obstruction.
