Effect of Pathogenesis-Based Individualized Thrombectomy on Treatment Result and Prognosis of Acute Intracranial Large-Artery Occlusion Patients

Background: To explore the effect and prognosis of individualized thrombus removal methods based on different pathogenesis. Methods151 patients with acute cerebral infarction who were admitted to the hospital for intracranial artery interventional thrombus removal from January 2018 to November 2019 were selected as the research objects. Patients in the experimental group selected different thrombectomy methods based on medical history, pathogenesis, and cerebrovascular angiography results. Aspiration and embolization are the first choice for embolism, and stent embolization is the first choice for vascular stenosis. Compare the medical history, admission NHISS score, the time from the end of cerebral angiography to recanalization, the number of thrombus removal, MRS score at 3 months, complications, etc . ResultsThere was no statistical difference in the basic data of the three groups. The time from the end of angiography to recanalization in the control group was significantly longer than that in the experimental suction group. There was a statistical difference between the control group and the experimental stent group in one-time thrombus removal opening rate (P=0.048). The vascular recanalization rate was statistically different among the three groups (P=0.611). The good prognosis rates of the experimental stent group and the experimental suction group were higher than those of the control group. ConclusionThe first choice for patients with cerebral infarction caused by embolization can shorten the recanalization time. Stent removal is the first choice for patients with cerebral infarction caused by atherosclerosis, which can increase the opening rate of thrombus removal. Individualized selection of different thrombus removal methods based on the pathogenesis can improve the good prognosis rate of patients.
