Radial artery occlusion (RAO) is a common complication during transradial coronary intervention. Its incidence is variably reported in literature and its predictors are not completely understood. In this study, we aimed to define the incidence and factors influencing RAO in patients undergoing transradial coronary intervention.
This was a single-center prospective study (October 2018 to September 2019) that enrolled 1,754 patients who were evaluated for RAO 24 hours after transradial coronary intervention. Univariate as well as multivariate analyses were done to identify patient and procedure related factors predicting the occurrence of RAO.
A total of 1,374 patients (78.3%) underwent angioplasty, whereas 380 (21.7%) underwent angiography alone. RAO was diagnosed in 11.97% patients. Lower glomerular filtration rate, multiple puncture attempts for radial artery access, larger sheath size, complex nature of interventional procedure, longer homeostasis time, and forearm hematoma formation were independent predictors for RAO.
RAO was not an uncommon complication in transradial coronary interventions, especially in the Indian population; and the knowledge of predictors may be helpful in its prevention.
桡动脉闭塞（RAO）是经桡动脉冠状动脉介入治疗中的常见并发症。其在文献中的发生率存在差异，其预测因素尚不完全清楚。在本研究中，我们旨在确定经桡动脉冠状动脉介入治疗患者中 RAO 的发生率和影响因素。
这是一项单中心前瞻性研究（2018 年 10 月至 2019 年 9 月），共纳入 1754 例患者，在经桡动脉冠状动脉介入治疗后 24 小时评估 RAO。进行单因素和多因素分析，以确定与患者和手术相关的预测 RAO 发生的因素。
共有 1374 例（78.3%）患者接受了血管成形术，而 380 例（21.7%）仅接受了血管造影。11.97%的患者诊断为 RAO。肾小球滤过率较低、桡动脉入路多次穿刺尝试、鞘管尺寸较大、介入手术复杂、止血时间较长和前臂血肿形成是 RAO 的独立预测因素。
RAO 在经桡动脉冠状动脉介入治疗中并非罕见并发症，尤其是在印度人群中；了解预测因素可能有助于预防。
