Biplanar Handheld Ultrasound for Transradial Artery Puncture

Brief Summary

Radial artery puncture is commonly used to obtain vascular access for cerebral angiography and neurointerventional procedures. Conventional ultrasound guidance usually provides either a short-axis or a long-axis view of the radial artery. A biplanar handheld ultrasound system can provide simultaneous long-axis and short-axis views, which may help the operator visualize the puncture needle and radial artery more clearly. This prospective, single-center, randomized, parallel-group superiority trial will compare the TUOREN biplanar handheld ultrasound system with a conventional high-frequency linear-array ultrasound system for ultrasound-guided radial artery puncture. A total of 152 adults scheduled to undergo cerebral angiography or neurointerventional treatment through a transradial approach will be randomly assigned in a 1:1 ratio to one of the two ultrasound-guidance groups. The main objective is to determine whether biplanar handheld ultrasound guidance improves the percentage of participants with successful radial artery cannulation on the first puncture attempt. Other assessments include the total number of puncture attempts, cumulative active puncture time, fixation time after successful cannulation, and the occurrence of posterior wall puncture.
