SBA with anastomosis, neither SBA nor anastomosis can be used in a 61-year-old woman with an unruptured cerebral aneurysm. Catheter insertion was not possible because the SBA was narrow. The anastomosis is broad but forms a loop, making it impossible to use for catheter insertion into the brachial artery. Angiography was switched to the left radial artery approach.
