Abstract 【Objective】 To investigate the application of three-dimensional (3D) technology based on digital subtraction angiography (DSA) in neurointerventional thrombectomy for patients with acute ischemic stroke (AIS).【Methods】 A total of 72 AIS patients were randomly divided into an observation group and a control group, with 36 patients in each group. The control group received intravenous thrombolytic therapy, while the observation group underwent neurointerventional thrombectomy assisted by DSA-based 3D technology in addition to intravenous thrombolysis. The vascular recanalization rate and cerebral hemodynamic parameters[middle cerebral arterial mean velocity (MV), cerebrovascular resistance (RV), and pulsatility index (PI)] were compared between the two groups at 1 week after treatment. Neurological function including modified Rankin Scale (mRS) score and National Institutes of Health Stroke Scale (NIHSS) score was assessed before treatment, at 1 week, and at 3 months after treatment.【Results】 At 1 week after treatment, the vascular recanalization rate in the observation group was higher than that in the control group. The observation group had a higher MV and lower RV and PI than the control group (P< 0.05). The mRS and NIHSS scores of the observation group were significantly lower than those of the control group at both 1 week and 3 months (P< 0.05). The overall incidence of adverse reactions in the observation group was also lower than that in the control group (P< 0.05).【Conclusion】 DSA-based 3D technology-assisted neurointerventional thrombectomy can significantly improve vascular recanalization, enhance cerebral perfusion, promote neurological recovery in AIS patients, and has good safety.
