Abstract

Background: The transradial approach (TRA) is preferred for coronary procedures due to improved outcomes and lower complication rates. However, complications such as radial artery stenosis (RAS) and occlusion (RAO) post TRA require investigation. This study aimed to explore the link between whole blood viscosity (WBV) and RAS/RAO after TRA coronary angiography.

Methods: A retrospective analysis of 215 TRA coronary angiography patients was conducted. Doppler ultrasonography assessed RAS/RAO one month post procedure. WBV, calculated from haematocrit and total plasma protein (TP), was evaluated at low (LSR) and high shear rates (HSR).

Results: RAS/RAO incidence was 15.3%, with 7.4% of patients experiencing RAO. Patients with RAS/RAO showed significantly elevated HSR, LSR and TP levels, with lower blood urea nitrogen levels. Multivariable analysis identified body mass index, HSR and LSR as independent RAS/RAO predictors.

Conclusions: This study established WBV association with RAS/RAO after TRA, suggesting WBV as a potential predictor and aiding pre-TRA risk assessment for alternative angiography routes.

经桡动脉冠状动脉造影后桡动脉狭窄与全血粘度的关系。

背景：经桡动脉入路（TRA）是冠状动脉手术的首选，因为它改善了预后，降低了并发症发生率。然而，术后并发症如桡动脉狭窄（RAS）和闭塞（RAO）需要调查。本研究旨在探讨TRA冠状动脉造影后全血粘度（WBV）与RAS/RAO之间的关系。方法：对215例TRA冠状动脉造影患者进行回顾性分析。术后1个月多普勒超声评估RAS/RAO。在低剪切率（LSR）和高剪切率（HSR）下，通过红细胞压积和总血浆蛋白（TP）计算WBV。结果：RAS/RAO发生率为15.3%，发生RAO的患者占7.4%。RAS/RAO患者的HSR、LSR和TP水平显著升高，血尿素氮水平降低。多变量分析发现，体重指数、HSR和LSR是独立的RAS/RAO预测因子。结论：本研究建立了腰宽与TRA后RAS/RAO的相关性，提示腰宽可作为潜在的预测因子，并有助于TRA前其他血管造影途径的风险评估。
