冠心病患者经桡动脉介入治疗后桡动脉闭塞的相关因素分析

Occurrence of radial artery occlusion after transradial interventional therapy in patients with coronary artery disease

目的分析冠心病患者经桡动脉介入治疗后桡动脉闭塞(RAO)发生的相关因素。方法选取96例接受经桡动脉介入治疗的冠心病患者,于术后1周、1个月及3个月采用多普勒超声检测穿刺侧桡动脉是否闭塞,根据1周时超声结果将患者分为RAO组(14例)及无RAO组(82例),比较两组患者的基本资料,分析RAO发生的相关因素。结果术后1周,女性患者RAO发生率为25.0%(9/36),高于男性患者的8.3%(5/60)(P<0.05);低体重患者RAO发生率为30.8%(4/13),高于正常体重患者的12.0%(10/83)(P<0.01)。RAO组术后随访1个月和3个月时分别有2例和8例桡动脉再通。结论经桡动脉介入治疗的冠心病患者中,女性及低体重患者较为容易发生RAO。术后3个月后超过半数的闭塞桡动脉可再通。

Objective To analyze the factors related to the occurrence of radial artery occlusion(RAO) after transradial interventional therapy in the patients with coronary artery disease.MethodsNinety-six patients with coronary artery disease underwent transradial intervention therapy.The patency of the radial artery was examined with Doppler ultrasound at one week,one month and 3 months after surgery.According to the results of ultrasound at one week,the patients were divided into group RAO(14 cases) and group NO-RAO(82 cases).The factors relevant to the RAO occurrence were analyzed.Results The incidence of RAO was higher in female patients than that in male one week after surgery [25.0%(9/36) vs.8.3%(5/60)](P<0.05).The incidence of RAO was higher in the patients with low body weight than that in those with nomal weight one week after surgery [30.8%(4/13) vs.12.0%(10/83)](P<0.01).During the follow-up of 1 month and 3 months,the recanalization of the occluded radial artery was seen in 2 patients and 8 patients,respectively.Conclusion RAO occurres more commonly in females and the patients with low body weight in the patients with coronary artery disease undergoing transradial intervention.More than half of the occluded radial arteries becomes repatent 3 months after surgery.
