Lu SS, Cao YZ, Su CQ, et al. - A retrospective study was performed to assess the clinical factors associated with hyperperfusion, and the 90‐day prognostic value of hyperperfusion after mechanical thrombectomy in acute ischemic stroke (AIS) patients. Researchers enrolled a total of 54 AIS patients who had undergone mechanical thrombectomy. They conducted time‐of‐flight MR angiography, pulsed arterial spin labeling (ASL), diffusion‐weighted imaging (DWI), and susceptibility‐weighted imaging at 3.0T within 1 week after thrombectomy. They further evaluated clinical factors including demographics, risk factors, stroke, and treatment characteristics. It was shown that hyperperfusion on ASL correlated with successful recanalization and may be an independent prognostic marker for good neurological outcomes at 90 days in AIS patients after mechanical thrombectomy.
