ABSTRACT

Objective To probe the safety of performing transradial artery percutaneous coronary intervention (PCI) for Allen test negative patients.Methods One hundred and six patients performed transradial artery PCI were enrolled in the study.The patients were divided into negative group (57 cases) and positive group (49 cases) according to Allen test results.Patients were performed ulnar artery angiography,deep palmar arch angiography and superficial palmar arch angiography.Ulnar artery diameter,deep palmar arch conditions,superficial palmar arch conditions,the frames counting through angiography on the side of ulnar vessel system,and hand ischemia after PCI (follow up for 3 months) was observed.Results There was no significant difference between negative group and positive group in parameters of ulnar artery diameter [(2.02 ±0.18) mm vs.(2.07 ±0.17) mm] and deep palmar arch and superficial palmar arch [85.96％ (49/57) vs.87.76％ (43/49),75.44％ (43/57) vs.81.63％ (40/49)] (P ＞0.05).The frames counting had no significant difference between negative group and positive group [(218.6 ± 63.6) frames vs.(180.8 ± 44.1) frames],but the ratio of the frames counting ≥380 frames had significant difference between negative group and positive group [14.04％(8/57) vs.2.04％(1/49)] (P ＜ 0.05).None of patients had been found to suffer from hand ischemia after PCI.Conclusion Transradial artery PCI is suitable for Allen test negative patients.
