Abstract
OBJECTIVE To evaluate the safety and efficacy of stenting for symptomatic intracranial atherosclerotic severe stenosis or occlusion with Enterprise stents. METHODS Fifty-three consecutive patients with symptomatic intracranial atherosclerotic severe (70%-99%) stenosis or occlusion who underwent endovascular treatment with Enterprise stents between September 2019 and March 2022 were retrospectively analyzed. Primary outcomes included technical stenting success rates, the incidence of complications within 30 days of the procedure, and the in-stent restenosis rates during the follow-up period. These outcomes were further categorized based on lesion location and operation time. RESULTS Fifty-seven lesions in 53 patients aged 61.0 ± 10.0 years were treated with Enterprise stents with a technical success rate of 100%. Seven patients (12.3%) had severe complications within 30 days of the procedure: five had a symptomatic ischemic stroke, one had a symptomatic intracerebral hemorrhage, and one had a subarachnoid hemorrhage related to the procedure. No deaths were observed. The rate of in-stent restenosis was 18.2%, with a mean vascular imaging follow-up period of 6.7 months. The 30-day complication and in-stent restenosis rates did not differ significantly between patients with different lesion locations and operation times (P > 0.05). CONCLUSION This retrospective study suggests that percutaneous transluminal angioplasty and stenting with Enterprise stents is an effective treatment for symptomatic intracranial arterial stenosis or occlusion with a high technical success rate. It also indicates that stenting during the early nonacute stage after stroke may not increase the incidence of perioperative complications for symptomatic intracranial atherosclerotic stenosis when following strict inclusion criteria.

Abstract
Cervical vertebrae may exhibit the anomalous presence of a double transverse foramen (DTF) that may impact the anatomy of related structures that traverse the cervical region, such as the vertebral artery (VA). This retrospective anatomical study utilized CT angiography cervical scans to examine the prevalence of DTF, VA, and TF areas. The subjects were separated into two groups: normal TF (NTF group; 26 males and 21 females) and double TF (DTF group; 21 males and 24 females). The males presented significantly higher TF area values (30.31 ± 4.52 mm2) than the females (27.48 ± 1.69 mm2) in the NTF group (p = 0.006). The sex differences disappeared when a DTF was present (p = 0.662). There were no differences in the VA area values between the sexes in both the NTF and DTF groups (p = 0.184). No significant differences in the VA area values between males of the NTF and DTF groups (p = 0.485) were noted. The DTF subjects presented an increased VA/TF area ratio than the NTF subjects (p < 0.001). This study showed that DTF presence reduced the TF area. In contrast, the VA area did not change despite the decreasing TF area. This might be an anatomical risk for transient vertebrobasilar insufficiency in subjects with DTF, especially in females, because VA space in the TF is less in DTF subjects than in NTF subjects. This may lead to easy VA compression in DTF subjects following neck trauma.

Abstract
BACKGROUND AND PURPOSE Tirofiban administration after mechanical thrombectomy (MT) remains controversial. This study aimed to investigate the efficacy and safety of adjunct tirofiban treatment following MT for acute ischemic stroke (AIS) patients with large vessel occlusion (LVO) that resulted in successful reperfusion on digital subtraction angiography (DSA). METHODS This retrospective study was conducted in Zhengzhou University University People's Hospital, an advanced stroke center in China. Consecutive patients with AIS who underwent endovascular therapy (EVT) were enrolled from June 2018 to January 2022. The safety endpoints were symptomatic intracerebral hemorrhage (sICH), total intracranial hemorrhage (ICH), and 3-month mortality. The efficacy endpoints were 3-month modified Rankin scale (mRS) score and 24-h neurological improvement. RESULTS A total of 145 consecutive patients with AIS who underwent MT were analyzed, of whom 51 (35.2%) patients were in the tirofiban group. There were 30 (20.7%) patients with sICH, 50 (34.5%) patients suffered from ICH within 24-h post-MT, and 47 (32.4%) dead at 3-month. Besides, 31 (21.4%) patients achieved excellent clinical outcomes (mRS, 0-1), and 24-h neurological improvement was found in 29 (20.0%) patients. No statistically significant differences were found in safety outcomes on sICH, total ICH, and 3-month mortality, as well as efficacy outcomes on 3-month mRS scores (0-1) and 24-h neurological improvement between the two groups (P > 0.05 for all). Additionally, tirofiban was associated with 3-month mRS scores of 0-2 (adjusted odds ratio (OR), 3.75; 95% confidence interval (CI), 1.41-10.02, P = 0.008). CONCLUSION Adjunct tirofiban treatment following MT for AIS patients with LVO that resulted in successful reperfusion on DSA was not correlated with the increased risk of safety endpoints on sICH, ICH, and 3-month mortality, and it may be associated with a lower 3-month mRS score.

Abstract
Symptomatic intracranial hemorrhage (SICH) is a catastrophic complication of endovascular treatment (EVT) for large vessel occlusion (LVO). We aimed to investigate the incidence and predictors of SICH after EVT. Patients were selected from the ANGEL-ACT registry. We diagnosed SICH according to the Heidelberg Bleeding Classification. Logistic regression analyses were performed to determine the independent predictors of SICH. Of the 1283 patients, SICH was observed in 116 patients (9.0%). On multivariable analysis, admission National Institutes of Health Stroke Scale (NIHSS) > 12 (odds ratio [OR] = 1.86, 95% confidence interval [CI]: 1.11-3.11, P = 0.018), admission Alberta Stroke Program Early CT Score (ASPECTS) < 6 (OR = 2.98, 95%CI: 1.68-5.29, P < 0.001), general anesthesia (OR = 1.81, 95%CI: 1.20-2.71, P = 0.004), prior intravenous thrombolysis (OR = 1.58, 95%CI: 1.04-2.40, P = 0.031), number of mechanical thrombectomy passes > 2 (OR = 1.68, 95%CI: 1.10-2.57, P = 0.016), and procedure duration > 96 min (OR = 1.82, 95%CI: 1.20-2.77, P = 0.005) were associated with high risk of SICH, whereas SICH was negatively associated with underlying intracranial atherosclerotic disease (OR = 0.45, 95%CI: 0.26-0.79, P = 0.021). The incidence of SICH after EVT for anterior LVO was 9.0% in ANGEL-ACT registry. Our study identified some predictors, which may assist doctors in identifying LVO patients with a high risk of SICH and making the optimal peri-procedural management strategies for such patients.

Abstract
Acute ischemic stroke due to basilar artery occlusion (BAO) carries a very poor prognosis. Functional outcomes in BAO patients undergoing endovascular therapy (EVT) may differ according to the specific pathological mechanisms. We aimed to explore the impact of the underlying pathological mechanisms on prognosis at 90-days and long-term follow-up in BAO patients treated with EVT. We analyzed consecutive BAO patients undergoing EVT from December 2012 to December 2018 at a single center (Xuanwu Hospital). Patients were classified into either an intracranial atherosclerotic disease (ICAD) group or an embolic group according to the corresponding angiographic findings. The baseline characteristics and functional outcomes were compared between the two groups. Multivariable logistic regression analysis was performed. Among the 167 patients enrolled, 78 patients (46.7%) were in the ICAD group and 89 patients (53.3%) were assigned to the embolic group. Overall, 149 patients (89.2%) achieved successful reperfusion post-EVT. There were no significant differences in functional outcomes at 90-days and long-term follow-up between the two groups. Similarly, a Kaplan-Meier survival analysis showed similar long-term survival probabilities (P = 0.438). The pathological mechanism was not associated with functional independence (OR, 1.818; 95% CI, 0.694-4.761; P = 0.224), favorable outcome (OR, 1.476; 95% CI, 0.592-3.681; P = 0.403), or mortality (OR, 1.249; 95% CI, 0.483-3.226; P = 0.646). However, based on subgroup analysis, embolic BAO versus ICAD was significantly associated with better functional independence in those aged 60 years and younger (OR, 4.513; 95% CI, 1.138-17.902). In this study, no differences in either 90-days or long-term functional outcomes between ICAD-related BAO and embolic BAO patients undergoing EVT were observed. However, in BAO patients aged ≤ 60 years, the pathological mechanism of embolism was associated with better functional independence.

Abstract
To investigate the safety and efficacy of intravenous administration of a standard dose of glycoprotein-IIb/IIIa inhibitor tirofiban after vessel recanalization by mechanical thrombectomy in acute ischemic stroke. A consecutive series of patients (n=112) undergoing endovascular ischemic stroke intervention therapy were enrolled. 81 patients were eligible for intravenous (IV) tirofiban treatment for 24 hours after mechanical thrombectomy. The incidence of symptomatic intracranial hemorrhage (sICH), death, National Institutes of Health Stroke Scale (NIHSS) and modified Rankin scale (mRS) were assessed. In the 81 patients receiving tirofiban, 52 patients (64.2%) were treated with IV rt-PA before mechanical thrombectomy. sICH was found in 2 (2.5%) patients with no fatal ICH. Four patients died during 3 months after stroke onset. Successful recanalization with thrombolysis in cerebral infarction (TICI) score ≥2b was achieved in 75 of 81 patients (92.6%) after mechanical thrombectomy. The average number of passes with Solitaire stent retriever was 1.3. At 3 months, 55 of 81 patients (67.9%) had favorable outcomes (mRS<=2). The intravenous application of a standard dose of tirofiban post-Solitaire stent retriever thrombectomy and intravenous thrombolysis appears to be safe and relatively effective in acute ischemic stroke.

Abstract
OBJECTIVES To evaluate a quantitative radiomic approach based on high-resolution magnetic resonance imaging (HR-MRI) to differentiate acute/sub-acute symptomatic basilar artery plaque from asymptomatic plaque. METHODS Ninety-six patients with basilar artery stenosis underwent HR-MRI between January 2014 and December 2016. Patients were scanned with T1- and T2-weighted imaging, as well as T1 imaging following gadolinium-contrast injection (CE-T1). The stenosis value, plaque area/burden, lumen area, minimal luminal area (MLA), intraplaque haemorrhage (IPH), contrast enhancement ratio and 94 quantitative radiomic features were extracted and compared between acute/sub-acute and asymptomatic patients. Multi-variate logistic analysis and a random forest model were used to evaluate the diagnostic performance. RESULTS IPH, MLA and enhancement ratio were independently associated with acute/subacute symptoms. Radiomic features in T1 and CE-T1 images were associated with acute/subacute symptoms, but the features from T2 images were not. The combined IPH, MLA and enhancement ratio had an area under the curve (AUC) of 0.833 for identifying acute/sub-acute symptomatic plaques, and the combined T1 and CE-T1 radiomic approach had a significantly higher AUC of 0.936 (p = 0.01). Combining all features achieved an AUC of 0.974 and accuracy of 90.5%. CONCLUSIONS Radiomic analysis of plaque texture on HR-MRI accurately distinguished between acutely symptomatic and asymptomatic basilar plaques. KEY POINTS • High-resolution magnetic resonance imaging can assess basilar artery atherosclerotic plaque. • Radiomic features in T1 and CE-T1 images are associated with acute symptoms. • Radiomic analysis can accurately distinguish between acute symptomatic and asymptomatic plaque. • The highest accuracy may be achieved by combining radiomic and conventional features.
