Comparison of Distal Transradial Access in Anatomic Snuffbox Versus Transradial Access for Coronary Angiography
Keywords:Distal radial artery, Percutaneous coronary angiography
Background: To compare distal transradial access (dTRA) in the anatomic snuffbox and conventional transradial access (cTRA) for coronary angiography.
Methods: Eighty cases that underwent coronary angiography were selected at The 903 Hospital of PLA in China from April 2017 to March 2018. Patients in the dTRA group underwent distal transradial access, and patients in the cTRA group received conventional transradial access. Puncture success rate, fluoroscopy time, and hemostasis time were determined.
Results: The puncture success ratio was 85% in the dTRA group and 100% in the cTRA group (P < .05). The fluoroscopy time was 36 minutes and 19 min minutes in the dTRA group and cTRA group (P < .05), respectively. The compression hemostasis time after operation was 120 minutes and 240 minutes in the dTRA group and cTRA group (P < .05), respectively. The complication rate in the cTRA group was 7.5%, while there was no complication in the dTRA group. In addition, there also was no significant difference between the two groups in the rate of complications (cTRA = 7.5%, dTRA = 0.0%, P > .05).
Conclusion: Distal transradial access in the anatomical snuffbox for coronary angiogram is a potential alternative to conventional radial arterial access.
