Background: Acute arterial occlusion in lower extremity is an urgent condition which occurs when there is an abrupt interruption of blood flow into an extremity. Reperfusion through early intervention can increase limb salvage and decrease mortality. There was no common agreement when is the best to start thrombolysis in treating acute arterial occlusion. This study was designed to study the efficacy of an early thrombolysis compared with a late thrombolysis.
Method: We identified all patients discharged from the Gwangju Veterans hospital with a diagnosis of acute arterial occlusion between 2006 and 2014. 72 patients were eligible, and every patient had treated with catheter-directed thrombolysis on the day or 1day after admission. Among them, 42 patients had undergone an early thrombolysis (less than 7days after the onset of symptoms) and the other 30 patients had undergone a late thrombolysis (more than 7days after the onset of symptoms). The primary outcome was amputation rate at 6months. The secondary outcomes were all cause mortality at 6months and increase of ankle brachial index (ABI).
Results: Amputation rate at 180days in the early thrombolysis group was 7.1% as compared with 30% in the late thrombolysis group. All cause mortality at 6months and increase of ABI were not different between two groups. In multivariable Cox-regression analysis, late thrombolysis was independent predictor of amputation at 6months.
Conclusion: Early thrombolysis was superior in preventing amputation than late thrombolysis.

Background: The aim of this study was to examine the impact of early versus delayed catheter-based therapies (CBTs) on clinical outcomes in patients with acute intermediate-risk pulmonary embolism (PE).
Methods: This retrospective cohort study analyzed data from 2 academic centers involving patients with intermediate-risk PE from January 2020 to January 2024. Patients were divided into early (<12 hours) and delayed CBT (≥12 hours) groups.
Impact of workflow times on successful reperfusion after endovascular treatment in the late time window.

Background And Purpose: Successful and complete reperfusion should be the aim of every endovascular thrombectomy (EVT) procedure. However, the effect of time delays on successful reperfusion in late window stroke patients presenting 6-to-24 h from onset has not been investigated.
Materials And Methods: We pooled individual patient-level data from seven trials and registries for anterior circulation stroke patients treated with EVT between 6 and 24 h from onset.

Importance: Reducing the burden of stroke is a public health priority. While higher stroke incidence among ethnic minority populations (defined in the context of this study as individuals who are not White) is well established, reports on ethnic inequalities in care or outcomes are conflicting and often limited to hospital-admitted patients and short-term outcomes.
Objective: To investigate ethnic differences in stroke care and outcomes up to 5 years after stroke and describe temporal trends and contributory factors.

Background: Whether it is effective and safe to extend the time window of intravenous thrombolysis up to 24 hours after the last known well is unknown. We aimed to determine the efficacy and safety of tenecteplase in Chinese patients with acute ischemic stroke due to large/medium vessel occlusion within an extended time window.
Methods: Patients with ischemic stroke presenting 4.
