TRACK-LVO: Triage of Patients With Acute Ischemic Stroke Due to Large Vessel Occlusions
Study Details
Study Description
Brief Summary
The aim of this study is to establish an academic, real-world, single-center, observational registry of consecutive patients hospitalized with acute ischemic stroke (AIS) due to large vessel occlusions (LVO), treated with either endovascular therapy (EVT) or best medical management (BMM).

Detailed Description
Stroke is a major threat to public health and is exacerbating socioeconomic development. It is the leading cause of mortality among residents in China. Large vessel occlusion (LVO) is a predictor of unfavorable outcomes and can account for up to 52% of patients with acute ischemic stroke (AIS). The definition of LVO and its optimal screening imaging modalities remain controversial. In this registry, the investigators defined LVO as an occlusion of the intracranial ICA with or without the involvement of the terminal bifurcation, M1 and/or M2 segment of the MCA, A1 and/or A2 segment of the ACA, VA, BA, or P1 and/or P2 segment of the PCA.
TRACK-LVO is an academic, real-world, single-center, observational registry, in which consecutive patients hospitalized with AIS due to LVO will be treated with either EVT or BMM. Baseline information and clinical follow-up information at 90 days from stroke onset are collected. The key baseline items in this registration for both EVT and BMM groups include basic demographic profiles, past medical history, NIHSS score, treatment with intravenous alteplase, type of stroke onset, time from stroke onset to admission/imaging, imaging characteristics such as volume of ischemic core and occlusion site, and treatment-related complications. Additional information collected in EVT groups includes details of EVT procedure and angiographic images.
The investigators enrolled patients with LVO screened under different imaging modalities to further reveal the optimal imaging modalities in the detection of LVO. The investigators also tend to compare the prognosis of AIS patients with LVO receiving endovascular therapy and best medical management respectively.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Endovascular therapy Timely thrombectomy for acute ischemic stroke patients with large vessel occlusion by either stent retriever, thrombus aspiration, others, or combination methods. |
Procedure: Endovascular Therapy
Endovascular therapy, as an adjunct to standard stroke therapy, may be beneficial for a very select population of patients who present with an acute ischemic stroke and have a proven large, proximal occlusion on imaging.
Endovascular therapy includes any one or more of the following:
Intra-arterial thrombolytic therapy, aspiration, stent retrieval, or a combination of multiple mechanical devices.

| Best medical management Patients enrolled in this group received the best medical management. |
Outcome Measures
Primary Outcome Measures
- Modified ranking scale (mRS) at 90 days [90 days]
The scale runs from 0-6, running from perfect health without symptoms to death.
- Mortality within 90 days [90 days]
mortality of any causes
Secondary Outcome Measures
- National Institutes of Health Stroke Scale (NIHSS) scores at 90 days [90 days]
The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0.
- Occurrence of periprocedural complications [14 days postoperatively]
Periprocedural complications include any intracranial hemorrhage, cerebral edema, brain herniation and pneumonia.
- ASPECT (Alberta Stroke Program Early CT score) [Day 0]
ASPECTS is a 10-point quantitative topographic CT scan score used in patients with middle cerebral artery (MCA) stroke.
