Abstract
Background
Tissue plasminogen activator (tPA) is an effective treatment for acute ischemic stroke. Although initial improvement is observed when administered for branch atheromatous disease (BAD), some cases subsequently worsen. Clinical data on the characteristics of these patients is lacking, and the benefits of tPA are unclear.
Objective
To analyze rebound cases and elucidate the clinical characteristics and outcomes associated with tPA administration in BAD.
Methods
This multicenter retrospective study was conducted in Japan. Worsening after initial improvement of a condition is termed as rebound, and such cases were compared with other types of ischemic stroke in patients with and without rebound. The characteristics of patients with BAD who rebounded were examined.
Results
The study included 93 patients. Among the patients who were administered tPA, the NIHSS scores at 24 h and 7 days post-tPA were significantly higher in patients with BAD than in patients with other types of infarcts. The group with BAD exhibited a significantly higher rate of rebound than other groups (37.5 % vs. 0 %, P < 0.001). However, no differences were observed in outcomes between patients who experienced rebound after tPA administration and those who did not.
Conclusions
Reevaluation and changing the strategy of tPA use in patients with BAD may be necessary. However, this study does not totally discourage its use, as specific patients can benefit.
期刊介绍:
The Journal of the Neurological Sciences provides a medium for the prompt publication of original articles in neurology and neuroscience from around the world. JNS places special emphasis on articles that: 1) provide guidance to clinicians around the world (Best Practices, Global Neurology); 2) report cutting-edge science related to neurology (Basic and Translational Sciences); 3) educate readers about relevant and practical clinical outcomes in neurology (Outcomes Research); and 4) summarize or editorialize the current state of the literature (Reviews, Commentaries, and Editorials).
JNS accepts most types of manuscripts for consideration including original research papers, short communications, reviews, book reviews, letters to the Editor, opinions and editorials. Topics considered will be from neurology-related fields that are of interest to practicing physicians around the world. Examples include neuromuscular diseases, demyelination, atrophies, dementia, neoplasms, infections, epilepsies, disturbances of consciousness, stroke and cerebral circulation, growth and development, plasticity and intermediary metabolism.
