Transradial and transfemoral accesses for cerebral angiography: a retrospective comparative study

ABSTRACT

Objective

Many large randomized trials in interventional cardiology have shown a significant advantage of transradial access (TRA) over transfemoral access (TFA). However, TRA has yet been widely used in Neurovascular interventional surgery. The purpose of this retrospective comparative study is to compare the effectiveness and safety of transradial and transfemoral accesses for cerebral angiography.

Methods

A total of 380 patients underwent cerebral angiography in our center between January 2019 and January 2021. Among them, 192 patients underwent TRA, and 188 patients via TFA. The success rate of cerebral angiography, X-ray time, total absorbed dose, dose-area product (DAP), complications, and other clinical data were extracted.

Results

The operative success (94.27% vs 97.87%; P = 0.071) and the puncture failure (1.56% vs 1.60%) were not significantly different between the TRA and TFA groups. Only arterial spasm, which is more common in the TRA group, was substantially different between the two groups in terms of surgical consequences (P = 0.015). In addition, there were no significant differences between the groups in total absorbed dose (P = 0.604) and DAP(P = 0.097). However, the X-ray time of the TRA group [281.50(216.30,342.00)] was shorter than the TFA group [296.50(230.80,363.50)] (P = 0.019).

Conclusions

TRA is effective and safe in cerebral angiography, and its use may be expanded.
