BackgroundThe transradial approach has slowly been gaining momentum in neuroendovascular procedures. We sought to assess its feasibility and safety and present a case series of transradial intraoperative angiography (IOA) during microsurgical clip ligation of intracranial aneurysms.MethodsThe setup and technique for transradial intraoperative angiography are described. Data on 10 consecutive patients undergoing IOA through the radial artery are presented.ResultsAll target vessels were successfully catheterized transradially, and conversion to the transfemoral access was not required in any of the cases. There was no access-site complication, such as hand ischemia, hematoma, or radial artery spasm. There were also no thromboembolic events causing a stroke. The average time for the IOA was 9.3 minutes.ConclusionsOur initial experience shows the transradial approach for IOA in clip ligation of aneurysms to be feasible and safe, with potential advantages over transfemoral IOA.Copyright © 2019 Elsevier Inc.
