桡动脉痉挛(RAS)是困扰经桡动脉入路经皮冠状动脉介入治疗(PCI)的一个难题(发生率12%~20%)。以往报道称,PCI术中在桡动脉内注射扩血管剂可以有效缓解痉挛,但尚缺乏随机临床试验的资料。法国学者Varenne等的SPASM研究为这方面提供了宝贵的经验。SPASM包含SPASM1和SPASM2两个连续
Radial artery spasm (RAS) is a dilemma (12% -20% incidence) that plagued percutaneous coronary intervention (PCI) via transradial approach. It has been reported in the past, PCI in the radial artery vasodilator injection can effectively relieve spasms, but the lack of randomized clinical trial data.
