The Feasibility Mechanism of Nerve Interventional Thrombectomy for Occlusion of Cranial Artery M1 and M2 Segments

Abstract

This study was aimed at exploring the feasibility and clinical efficacy of nerve interventional thrombectomy (NIT) to treat occlusion of cranial artery M1 and M2 segments. 80 patients were selected and rolled into a control group (intravenous thrombolysis) and an experimental group (NIT). Patients’ vascular recanalization rates following therapy were compared, and the National Institutes of Health Stroke Scale (NIHSS) was used to measure neurological function. The improvement in hemodynamics and the occurrence of adverse responses were compared. The results showed that the experimental group’s recanalization rate was up to 74.23%, which was significantly greater than the control group’s ( $P<0.05$ ). One week after treatment, the neurological function scores in both groups decreased, and the score in the experimental group was only 15.23, which was much lower than that in the control group ( $P<0.05$ ). The peak systolic flow rates of the basilar artery, internal carotid artery, and common carotid artery in the experimental group were 132 cm/s, 147 cm/s, and 114 cm/s, respectively, which were lower greatly than those in the control group ( $P<0.05$ ). There was no significant difference in incidence of adverse reactions between the two groups ( $P>0.05$ ). In summary, NIT showed a significant therapeutic effect on cranial artery occlusion of M1 and M2 segments, can dredge the occluded blood vessels, and effectively improve the neurological deficits of patients, showing reliable feasibility.
