RADIOLOGY: What kind of acute vertebral underlying artery recital patients have good intravascular treatment effect?

Background
the clinical decision-making of acute vertebral underlying arterial protocracy (EVT) is controversialpurpose
this study aims to identify preoperative predictive indicators with good post-EVT effects in VBO patients and establish a model to assist the treatment choices of VBO patientsmaterials and methodsfor this retrospective study from multicenter in Korea, a good predictive model (mRS score 0-2) based on VBO patient data was establishedPreoperative indicators including onset-puncture time, cerebral infarction volume, blocking type (as an alternative indicator of intracranial atherosclerosis or embolism), and lateral circulatory function were analyzedTwo classifications of continuous variables are performed based on ROCUse the multi-regression model to generate a predictive modelThe model is verified by bootstrap method, and the single-center sample is verifiedresultsa predictive model was established by analyzing 71 patients and validated in 32 patientsDW imaging infarction volume at the onset of disease 10ml (OR, 19.3; 95% CI: 3.0, 126.4; PPThese indicators can be used to predict a good postoperative prognosis for EVT, with an area of 0.86 (IQR, 0.77-0.95; bootstrap optimism corrected-C statistic, 0.837), 0.78 (IQR, 0.62-0.95) under the median curve of the test group and the validation groupThe results show that the side branch cycle function is not correlated with the prognosis (P - .67)conclusion
when patients with vertebral underlying artery infarction choose intravascular therapy, the patient's incidence-puncture time of 8 hours, the initial cerebral infarction volume of 5 ml and the appearance of perforated propane crest performance can indicate a better prognosis
