Splenic Responses in Ischemic Stroke: New Insights into Stroke Pathology.

Splenic Responses in Ischemic Stroke: New Insights into Stroke Pathology. CNS Neurosci Ther. 2014 Dec 5; Authors: Liu ZJ, Chen C, Li FW, Shen JM, Yang Y, Leak RK, Ji X, Du H, Hu X Abstract In the past decade, the significant contribution of the spleen to ischemic brain damage has gained considerable attention in stroke research. As the largest natural reservoir of immune cells, the spleen establishes critical connections with the ischemic brain during the progression of stroke and mobilizes its cells to the site of injury. Multiple "alarm" signals released from the injured brain are essential for the initiation of brain-spleen communication. Spleen-derived cells, including neutrophils, lymphocytes, and monocytes/macrophages, are known to contribute significantly to ischemic brain damage. Understanding the dynamic splenic responses to stroke will not only provide insights into the evolvement of ischemic brain injury but will also identify potential targets for stroke treatment. Here, we review recent studies on the functions of the spleen in ischemic stroke. We have included a discussion of several therapeutic strategies that target splenic responses and reduce acute ischemic brain damage in preclinical studies. Future investigations on the effects of the spleen on long-term stroke recovery are highly warranted. PMID: 25475834 [PubMed - as supplied by publisher]

We present a unique case of an anterior ST elevation myocardial infarction as a result of coronary embolism, the source of which appears to be calcific debris from mitral annular calcification (MAC). Although embolic phenomena in the setting of MAC has been documented previously, particularly in the setting of acute ischemic stroke, to our knowledge this is the first reported case in the literature where MAC alone appears to have resulted in a coronary embolic event.

METHODS: In-hospital recovery was defined as an improvement of 4 points or> 40% in the National Institutes of Health Stroke Scale (NIHSS) score ...

The 2015 trials for interventional management of stroke yielded high rates of recanalization and good functional outcome. The DAWN (DWI or CTP Assessment with Clinical Mismatch in the Triage of Wake-up and Late Presenting Strokes Undergoing Neurointervention with Trevo; NCT02142283) and DEFUSE 3 (Endovascular Therapy Following Imaging Evaluation for Ischemic Stroke 3; NCT02586415) trials (1,2) demonstrated effectiveness for up to 24 hours (2). The workflow analysis of the SWIFT-PRIME (Solitaire with the Intention for Thrombectomy as PRIMary Endovascular Treatment; NCT01657461) trial data showed that there was a 91% probabi...
