Abstract:

BACKGROUND: There has rarely reported about the epidemiological study on vascular tortuosity and variation of radial artery in the southerner of China.
OBJECTIVE: To investigate the incidence and clinical predictors of arterial anatomical variations of radial artery approach (RAA) in the southerner of China.
METHODS: Totally 1 400 patients who underwent first-time transradial coronary procedures were included in this study. A detailed patient history was recorded. Radial arteriography was performed in all patients to detect the anatomic variations of this vessel. And then coronary angiography or percutaneous coronary intervention was undertaken. Multivariate Logistic regression analysis was performed to evaluate the predictive value of variables in arterial variations of RAA.
RESULTS AND CONCLUSION: For people in southern China, the tortuosity of subclavian artery and radial artery was most common among vascular anatomic variations of the RAA. The overall rate of transradial procedural success rate was 96.1%. Procedural failure rate was more common in patients with anomalous RAA than in patients with normal RAA (15.1% vs 1.8%, P < 0.001). According to multivariate Logistic regression analysis, age, female gender, height, body mass index, hypertension, hyperlipidemia and smoking were independently associated with arterial anatomical variations of RAA.
