Compared with a femoral approach, studies have shown increased radiation exposure with transradial approach (TRA). Right radial approach (RRA) is preferred over a left radial approach (LRA) due to perceived increased operator discomforts with LRA. However, no randomized study has evaluated these differences between the two TRA. The aim of this study was to determine difference in operator radiation exposure and physical discomfort using LRA versus RRA.
One hundred patients without prior CABG were randomized to a LRA or RRA. To prevent imbalances, patients were stratified by BMI and each operator had an independent randomization. Dosimeter badges were placed on external head, thyroid and internal sternum. To determine operator radiation, radiation exposure was adjusted to fluroscopy time (FT). Operator physical discomfort (back, leg, neck pain) was surveyed at two time points; during vascular access and at the end of the procedure.
There were no significant differences in baseline and procedural variables between groups. There was a significant decrease in radiation exposure to the operator using the LRA. Even though, more discomfort was reported during LRA access, no discomfort differences were observed during the procedure (Table).
Compared with RRA, LRA is associated with more discomfort only during vascular access, but with no discomfort differences during the procedure. LRA is as effective as RRA showing a safer profile with decreased operator radiation.
