Abstract:
Objective To monitor the number of microembolic signals(MES)during endovascular recanalization of symptomatic non-acute internal carotid artery occlusion(NA-ICAO),to investigate the risk steps for MES during sur-gery,and to improve the safety of endovascular treatment(EVT).Methods A prospective study was conducted among 56 patients with symptomatic NA-ICAO who received EVT from April 1,2022 to June 30,2023.The number of MES was recorded during the seven steps of reperfusion treatment,and transcranial Doppler was used for statistical analysis.All pa-tients underwent magnetic resonance imaging before and after surgery.According to the results of MES and the presence or absence of new infarcts on diffusion-weighted imaging(DWI)after surgery,the patients were divided into DWI(+)group and DWI(-)group.Results A relatively large number of MES was observed for both groups in the steps of searching for the true cavity through the occlusive segment with microguide wire(with a mean number of 21.81 and 17.75,respec-tively;P<0.05)and predilation for the first time(with a mean number of 23.29 and 17.43,respectively;P<0.05),and the number of new infarcts after surgery was significantly positively correlated with the total number of MES during surgery.Conclusion The steps of searching for the true cavity through the occlusive segment with microguide wire and predilation for the first time may easily induce MES,and the number of MES during surgery is correlated with infarcts after surgery.It is speculated that intraoperative MES is associated with new infarcts after surgery.
