Core Tip

Core tip: Hyperperfusion syndrome is a relatively rare, but potentially serious, complication of carotid revascularization procedures. It is important to detect the excessive increase blood flow after treatment as soon as possible. We found that, although the observed blood flow increase in the digital subtraction angiography system did not strongly correlate with the rate of increase of single-photon emission computed tomography before and after carotid artery stenting, the digital subtraction angiography flow assessment application more finely reflected the rate of change of the vessels well.
