Core Tip
Core tip: Balloon test occlusion (BTO) is widely performed to assess the ischemic tolerance among preoperative patients. It is safe and useful, however, it sometimes carries the risk of thrombosis, dissection and infarction. Our study revealed that visualizations of the anterior cerebral artery and middle cerebral artery (MCA) as well as the circle of Willis (COW) anatomy were significantly associated with the BTO result. In particular, good MCA visualization and/or the presence of an anterior connection [collateral path to the tested internal carotid artery (ICA) from the contralateral ICA via the anterior communicating artery] in the COW were highly predictive for negative BTO.
