ABSTRACT
BACKGROUND:
The radial artery approach has become popular as a 'radial first' strategy for arterial access in neuroangiography and neurointerventions. Recent studies have shown that transradial arterial access (TRA) for cerebral angiography has been associated with reduced access site complication rates and improved patient satisfaction compared with transfemoral access (TFA). The goal of this study was to evaluate the presence of abnormal MRI diffusion weighted imaging (DWI) foci following DSA and correlate their frequency with TRA or TFA.METHODS:
We prospective analyzed 200 consecutive adult DSAs performed from January 2021 to January 2022, at a single tertiary center.RESULTS:
Of the 200 consecutive diagnostic cerebral angiograms, 51% were performed via TRA and 49% were performed via TFA. Of the TRA cerebral angiograms, 17.5% demonstrated at least one hyperintense focus on MRI DWI. Of the TFA procedures, 5.2% were considered positive. One patient (0.5%) in the TRA group experienced a minor neurologic deficit postoperatively that had not completely resolved at 90 days after the procedure and no neurologic deficits occurred in the TFA group.CONCLUSIONS:
Despite the proven benefit of TRA over TFA in neurointervention, the number of MRI DWI restriction foci were significantly more frequent during cerebral angiography when TRA was selected. Although the number of clinically symptomatic events were minimal, the widespread use of the technique may become clinically relevant. Further studies contrasting the TRA and TFA techniques will be beneficial for cerebral angiography.Palavras-chave
