    Abstract:
    BACKGROUND AND PURPOSE: Vascular complications following transradial coronary angiography and coronary intervention could severely compromise perfusion of the hand. Drastic complications after cannulation of the radial artery (ischemia of the hand with occlusion of the digital arteries) are published only in brief reports. This study investigates whether percutaneous transradial artery coronary angiography/intervention results in vascular complications. PATIENTS AND METHODS: 93 patients were consecutively studied over a 4-month period. The following data were recorded before and after coronary angiography and/or intervention: diameter of the radial artery, blood volume, flow velocity, and occlusion pressure. Graduation of the stenosis after intervention was done according to the principle of the peak velocity ratio. RESULTS: A transradial coronary angiography/intervention was performed in 93 patients (75 men, mean age 62.5 years) in case of an unremarkable Allen test. Procedural success rate was 97.2%. The intervention could not be completed successfully in three patients (2.8%). Mean vessel diameter increased from 2.46 +/- 1.7 mm (standard deviation [SD]) before intervention to 2.78 +/- 0.69 mm (SD) after intervention; this increase was statistically significant (p = 0.002). Changes in blood flow, flow velocity and occlusion pressure did not reach significance. Vascular complications were seen in nine of 93 patients (10%) after the procedure. No patient mentioned discomfort. No perfusion deficit of the digital arteries was seen. CONCLUSION: The transradial coronary angiography and intervention is a safe method with a high procedural success rate.
