Computational fluid dynamics-derived flow helicity and recurrent stroke risk in symptomatic intracranial stenosis

Kai Zhang, Xinxin Shi, Yibo Yan, X.S Liu et autres

BACKGROUND: Patients with symptomatic intracranial atherosclerotic stenosis (ICAS) remain at risk of recurrent ischemic events despite treatment. Stenosis severity is routinely used for risk assessment, but does not describe the lesion-level flow field. We used computational fluid dynamics (CFD) to assess whether …

Durable fluoropolymer drug-eluting stent versus bare-metal stent for the prevention of intracranial in-stent restenosis

Ying Yu, Xuan Wang, Liangfu Zhu, Chengbo Dai et autres

BACKGROUND: The high incidence of in-stent restenosis (ISR) associated with bare-metal stents (BMS) undermines the viability of endovascular treatment as a treatment option for patients with severe symptomatic intracranial atherosclerotic stenosis (ICAS). The study aimed to evaluate whether durable fluoropolymer drug-eluting stents …

Risk factors and outcomes of patients with early spontaneous recanalization after acute middle cerebral artery occlusion

Mingyao Li, Weilun Fu, Kai Zhang, Zhikai Hou et autres

Background: Several studies have shown that spontaneous recanalization after acute intracranial arterial occlusion is not uncommon. This study aimed to investigate the predictive factors and outcomes of early spontaneous recanalization following acute middle cerebral artery occlusion. Methods: We conducted an analysis of …

Argatroban in patients with acute ischemic stroke with early neurological deterioration: a cost-effectiveness analysis from the perspective of Chinese healthcare system

Yu Xie, Liping Hu, Ping Xu, Xianbin Guo et autres

Background and Objective: Studies have shown that argatroban improves 90-day functional outcomes in patients with acute ischemic stroke (AIS) with early neurological deterioration (END). However, its cost-effectiveness in this patient population remains unclear. Methods: A combination of a short-term decision tree and …

Tenecteplase for ischemic stroke at 4.5 to 24 hours without thrombectomy: a cost-utility analysis from the perspective of Chinese healthcare system

Maolin Chen, Ying Yu, Bo Yu, Yudan Cao et autres

Background: Tenecteplase improves functional outcomes in acute ischemic stroke (AIS) patients treated 4.5 to 24 h after symptom onset who do not undergo thrombectomy. However, its cost-utility remains unexamined. Methods: A hybrid model combining a short-term decision tree and a long-term Markov …

Tmax >4 s volume predicts stroke recurrence in symptomatic intracranial atherosclerotic stenosis with optimal medical treatment

Ying Yu, Junchao Yu, Zhikai Hou, Tse-cheng Chiu et autres

BACKGROUND: The time to maximum (Tmax) profile based on computed tomography perfusion (CTP) provides a quantitative assessment of cerebral hemodynamic compromise. We aimed to delineate the Tmax profile in stroke patients with symptomatic intracranial atherosclerotic stenosis (ICAS) and to investigate its predictive …

Effects of different endovascular treatments on cerebral perfusion changes and stroke recurrence in patients with intracranial atherosclerosis

Jiayin Zhang, Zhe Wang, Zhikai Hou, Ying Yu et autres

BACKGROUND: In patients with refractory intracranial atherosclerotic disease (ICAD), percutaneous transluminal balloon angioplasty (PTBA) is less complex but typically results in higher postprocedural residual stenosis than percutaneous transluminal angioplasty with stenting (PTAS). METHODS: This study included patients with symptomatic ICAD with 70-99% …

Semi-automatic computed tomography angiography quantification assessment is an alternative method to digital subtraction angiography in intracranial stenosis: a multicenter study

Long Yan, Ying Yu, Bo Yang, Weilun Fu et autres

Background: The recent randomized controlled trials studying intracranial atherosclerotic stenosis (ICAS) have used digital subtraction angiography (DSA) to quantify stenosis and enroll patients. However, some disadvantages of DSA such as invasive features, contrast agent overuse, and X-ray radiation overexposure, were not considered …
