Abstract

Background Use of the radial artery as an access site for neurointerventional procedures is gaining popularity after several studies in interventional cardiology have demonstrated superior patient safety, decreased length of stay, and patient preference compared with femoral artery access. The transradial approach has yet to be characterized for intraoperative cerebral angiography. Objective To report a multicenter experience on the use of radial artery access in intraoperative cerebral angiography, including case series and discussion of technical nuances. Methods 27 patients underwent attempted transradial cerebral angiography between May 2017 and May 2019. Data were collected regarding technique, patient positioning, vessels selected, technical success rate, and access site complications. Results 24 of the 27 patients (88.8%) underwent successful transradial intraoperative cerebral angiography. 18 patients (66.7%) were positioned supine, 6 patients (22.2%) were positioned prone, 1 patient (3.7%) was positioned lateral, and 2 patients (7.4%) were positioned three-quarters prone. A total of 31 vessels were selected including 13 right carotid arteries (8 common, 1 external, 4 internal), 11 left carotid arteries (9 common and 2 internal), and 6 vertebral arteries (5 right and 1 left). Two patients (7.4%) required conversion to femoral access in order to complete the intraoperative angiogram (1 due to arterial vasospasm and 1 due to inadvertent venous catheterization). One procedure (3.7%) was aborted because of inability to obtain the appropriate fluoroscopic views due to patient positioning. No patient experienced stroke, arterial dissection, or access site complication. Conclusions Transradial intraoperative cerebral angiography is safe and feasible with potential for improved operating room workflow ergonomics, faster patient mobility in the postoperative period, and reduced costs.
