Abstract：Objective To explore the application effect of PDCA circulation mode in the mechanical thrombectomy guided by digital subtraction angiography(DSA)for the treatment of cerebral infarction patients.Method A longitudinal controlled study was conducted,selecting 50 patients with cerebral infarction admitted to the hospital from October 2022 to October 2023 as the study group.DSA-guided mechanical thrombectomy under PDCA cycle mode was planned to be performed.In addition,the data of 50 patients with cerebral infarction admitted from September 2021 to September 2022 were collected as the control group.All patients in the control group were completed mechanical thrombectomy under routine DSA guidance.The vascular re-canalization rate between two groups of patients after thrombectomy,neurological function before and 7 days after thrombectomy[National Institutes of Health Stroke Scale(NIHSS)score],functional recovery 90 days after surgery[Modified Rankin Scale(mRs)score]were compared,and complications were calculated.Result The postoperative vascular recanalization rate in the study group was higher than that in the control group(P<0.05).Before treatment,there was no statistical significant difference in NIHSS scores between the two groups(P>0.05).7 days after surgery,the NIHSS scores of the two groups decreased,and the study group was lower than the control group(P<0.05).The functional recovery of the study group after 90 days of surgery was better than that of the control group(P<0.05).The incidence of postoperative bleeding transformation and puncture point bleed-ing in the study group was lower than that in the control group(P<0.05).Conclusion The application of PDCA circulation mode in DSA-guided mechanical thrombectomy for the treatment of cerebral infarction patients has an ideal effect,which can im-prove vascular recanalization rate,promote neurological function recovery,increase the safety of thrombectomy treatment,and reduce the occurrence of related complications.
