Temporal trends in endovascular therapy for acute stroke in the era of modern mechanical thrombectomy: The JR-NET4 study
Objectives
This study aimed to examine nationwide trends in acute stroke endovascular thrombectomy (EVT) following five pivotal trials in 2015 that established it as the ‘standard of care’.
Methods
The Japanese Registry of NeuroEndovascular Therapy 4 was a nationwide retrospective study registering consecutive patients who underwent neurointervention by specialists certified by the Japanese Society for Neuroendovascular Therapy at 166 centers from January 2015 to December 2019. We extracted patients who underwent EVT, and analyzed the annual trends in baseline characteristics, revascularization procedures and outcomes.
Results
A total of 13,090 patients (75.3 ± 12.2 years, 5637 women) were included. Analyses revealed an annual increase in patient age and treatments beyond 6 h after onset. However, there was an annual decline in premorbidly independent patients and those with large vessel occlusion. The frequency of stent-aspiration techniques and rate of successful reperfusions significantly increased from 19.9 % to 51.0 % and from 81.4 % to 83.9 %, respectively through the study period. Trends in patients achieving a favorable (modified Rankin Scale score of 0-2 at 30 days) or fatal outcome, or experiencing intracranial hemorrhagic complications remained unchanged. However, calendar time was associated with favorable outcomes after adjusting for clinical and treatment characteristics (odds ratio, 1.040; P = 0.015).
Conclusions
During the study period, EVT indications expanded for patients with characteristics linked to worse outcomes. However, factors such as advancements in techniques, have led to modest but significant improvements in reperfusion status, leading to maintenance of the post-EVT clinical outcomes.
期刊介绍：
The Journal of Stroke & Cerebrovascular Diseases publishes original papers on basic and clinical science related to the fields of stroke and cerebrovascular diseases. The Journal also features review articles, controversies, methods and technical notes, selected case reports and other original articles of special nature. Its editorial mission is to focus on prevention and repair of cerebrovascular disease. Clinical papers emphasize medical and surgical aspects of stroke, clinical trials and design, epidemiology, stroke care delivery systems and outcomes, imaging sciences and rehabilitation of stroke. The Journal will be of special interest to specialists involved in caring for patients with cerebrovascular disease, including neurologists, neurosurgeons and cardiologists.
