Objective To observe the efficacy and safety of mechanical thrombectomy in acute ischemic stroke patients after vertebral-basilar artery stent implantation.Methods From May 2018 to October 2022,patients with acute vertebral basilar artery occlusion who underwent mechanical thrombectomy were retrospectively analyzed.The patients were divided into two groups:stent occlusion group and acute atherosclerotic stenosis occlusion(ICAS)group.The baseline characteristics of the two groups were balanced by propensity score matching method.The successful recanalization rate,90-day good outcome rate,90-day mortality rate,and symptomatic intracranial hemorrhage rate were compared.Results We enrolled 107 patients,with 14 cases in stent occlusion group and 93 cases in ICAS group.We analyzed 14 pairs by propensity score matching,including 14 cases in stent occlusion group and 27 cases in ICAS group.The successful recanalization rate and 90-day good outcome rate was lower in stent occlusion group than in ICAS group[(78.6％(11/14)vs.100％(27/27),P=0.062,28.6％(4/14)vs.44.4％(12/27),X2=0.976,P=0.323],but there was no statistical difference.The 90-day mortality rate in the stent occlusion group was significantly higher than that in the ICAS group[57.1％(8/14)vs.25.9％(7/27),x2=3.873,P=0.049].The incidence of symptomatic intracranial hemorrhage was higher in the stent occlusion group than in the ICAS group,with no statistical difference[35.7％(5/14)vs.14.8％(4/27),x2=1.289,P=0.256].Conclusion The successful recanalization rate,90-day good outcome rate,and incidence of symptomatic intracranial hemorrhage in stent occlusion group did not significantly differ from those in ICAS group,but the 90-day mortality rate was significantly higher in the former group.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective To investigate the value of a clinical-CT radiomics model in predicting cervical lymph node metastasis(CLNM)of papillary thyroid carcinoma(PTC).Methods A total of 262 cases with PTC confirmed by pathology after surgery were selected.On CT arterial phase images,the PTC was outlined layer by layer via software 3D-slicer to extract CT radiomics features.The least absolute shrinkage and selection operator(LASSO)algorithm was used for dimensionality reduction and feature screening in relation to CLNM.The Mann-Whitney U test or Chi square test was performed to identify clinical parameters significantly associated with CLNM.The statistically significant CT radiomics features and clinical parameters were all selected for the multivariate logistic regression analysis to construct the clinical-CT radiomics model.The predictive efficiency of model was evaluated via the receiver operating characteristic(ROC)curve.Results The clinical-CT radiomics model demonstrated favorable predictive performance in both the training group[area under the curve(AUC)0.804,sensitivity 68.7％,specificity 82.4％]and the validation group(AUC 0.782,sensitivity 84.4％,specificity 61.8％).Conclusion The clinical-CT radiomics model demonstrates significant value in predicting CLNM of PTC,thereby,aiding in the development of personalized clinical plans for cervical lymph node(CLN)dissection.

Objective:To investigate the pathogenesis, selection of endovascular treatment (EVT) strategies, and efficacies of acute vertebrobasilar artery occlusion (AVBAO) of different lesion sites.Methods:One hundred and five patients with AVBAO, admitted to and accepted EVT in our hospital from February 2017 to September 2019, were chosen in our study. The data of disease onset, imaging findings, EVT status, perioperative complications, and prognoses of these patients were collected. According to DSA results, the involved lesions were divided into 4 sites: the upper segment of basilar artery (BA), the middle segment of BA, the lower segment of BA, and the intracranial segment of vertebral artery (V4 segment), and patients with tandem lesions would be recorded as distal lesions. The risk factors, EVT strategies, and prognoses 90 d after follow-up (modified Rankin scale [mRS] scores≤3: good prognosis) were compared in patients with 4 different lesion sites.Results:There were significant differences in etiological classifications and percentage of patients combined with atrial fibrillation among patients with 4 different lesion sites ( P<0.05). There was significant difference in proportion of patients accepted emergency stent implantation among patients with 4 different lesion sites ( P<0.05): those with lesions at the V4 segment had the highest proportion of patients accepted emergency stent implantation (79.55%), followed by those with lesions at the lower segment of BA (50.00%). There was significant difference in EVT time (the time from arterial puncture to successful recanalization of occluded vessels) among patients with 4 different lesion sites ( P<0.05): the EVT time in patients with lesions at the middle segment of BA was the shortest (87.5 [58.5, 130.8] min), and the EVT time in patients with lesions at the lower segment of BA was the longest (115.0 [81.0, 163.0] min). There was no statistical difference among patients with different lesion sites in good prognosis rate 90 d after follow-up ( P>0.05). Conclusion:The pathogenesis of patients with different AVBAO lesion sites is different, so different EVT strategies should be adopted.

Objective:To observe the changes of left ventricular energy loss(EL) and apical wall shear stress(WSS) in patients with ventricular aneurysm by using vector flow mapping (VFM).Methods:Twenty-seven patients with ventricular aneurysm were selected as the case group, and they were divided into the ventricular aneurysm group(16 cases) and ventricular aneurysm thrombus group(11 cases) according to whether the apex of the heart was accompanied by thrombosis. Twenty healthy people were collected as the control group. Ventricular structure and cardiac function parameters were measured and the VFM offline analysis was performed. Systolic and diastolic phases were determined based on time-flow curve(T-F curve) and the open-close of valves, the corresponding left ventricular energy loss and the parameters of the WSS of the apex segment of the heart were obtainedand then compared between groups.Results:①In diastolic and systolic phases, EL values of left ventricular apical segment in ventricular aneurysm group and ventricular aneurysm thrombus group were lower than that in control group (all P<0.05). ②In diastolic phase, the peak WSS values of septal apical, lateral apical and anterior apical segments in ventricular aneurysm group and ventricular aneurysm thrombus group were lower than those in control group (all P<0.05), and the mean WSS of anterior apical segment in aneurysm group was lower than that in control group ( P<0.05). ③In systolic phase, the peak WSS values of anterior wall in ventricular aneurysm group and ventricular aneurysm thrombus group were lower than those in control group, and the mean WSS of anterior wall in ventricular aneurysm group was lower than that in control group (all P<0.05). The mean WSS of anterior wall in ventricular aneurysm thrombus group was higher than that in ventricular aneurysm group( P<0.05). Conclusions:VFM technology can quantitatively evaluate the EL and WSS of patients with left ventricular aneurysm, and provide a new perspective for further understanding of intracardiac hemodynamics in patients with left ventricular aneurysm with or without thrombus.

Objective:To investigate the efficacy and safety of endovascular recanalization treatment for acute vertebral basilar artery occlusion (AVBAO) underlying intracranial atherosclerotic disease (ICAD) using a balloon-mounted stent.Methods:A total of 16 cases of consecutive AVBAO patients who underwent endovascular treatment with the balloon-mounted stent within 24 h after onset were retrospectively enrolled in Henan Provincial People′s Hospital from February 2017 to August 2019. And the recanalization rate, operation-related complications, symptomatic intracranial hemorrhage, the improvement of 1 week National Institutes of Health Stroke Scale (NIHSS) score and 3 months modified Rankin Scale (mRS) after treatment were recorded.Results:In all of the 16 patients, 4 patients underwent direct stenting angioplasty, 12 patients received salvage stenting. Stent placement was successful in all 16 patients. Balloon-mounted stent were implanted in basilar artery of 4 cases, in intracranial segment of vertebral artery of 8 cases, and in origination segment of vertebral artery of 4 cases. Recanalization was successful (thrombolysis in cerebral infarction grade 2b and 3) in 15 patients. The time between arterial puncture and recanalization was 79.0 (72.3, 109.3) min. One patient experienced distal thrombosis during surgery. Two patients suffered symptomatic intracranial hemorrhage within 48 h after surgery. The scores of the NIHSS were improved more than 4 points at 1 week after operation in 8 patients. At 3 months follow-up, 9 patients had a good outcome (mRS 0-3 points) and 4 patients died.Conclusion:Selective stenting angioplasty treatment with a balloon-mounted stent seems to be feasible and safe for AVBAO patients underlying ICAD.
