INTRODUCTION: Observational and interventional studies indicate that the type of anaesthesia may be associated with the postprocedural neurological function in patients with anterior circulation acute ischaemic stroke undergoing endovascular treatment. Patients with acute posterior circulation ischaemic stroke may experience different physiological changes and result in severe neurological outcome. However, the effect of the type of anaesthesia on postprocedure neurological function remained unclear in this population...

BACKGROUND: In January 2018 The Joint Commission introduced its Thrombectomy-Capable Stroke Center (TSC) certification program to recognize hospitals capable of performing endovascular thrombectomy for patients with ischemic strokes due to large vessel occlusions, intended for hospitals not in close geographic proximity to Comprehensive Stroke Centers (CSCs). This study was conducted to determine (1) the travel times between current and potential TSCs and the nearest CSC and (2) the proportion of TSCs that were in areas of high need...

BACKGROUND: Currently, DES is a reasonable treatment option for LMCA disease but CABG continues to be first-line treatment. Multiple randomized clinical trials (RCTs) have compared outcomes between these two treatment modalities. Recently, these trials published their long-term results with conflicting findings. METHODS: We conducted a systematic review and meta-analysis of RCTs that compared DES vs CABG in patients with LMCA disease. We only included trials with follow up duration of at least 5 years...

BACKGROUND: Forefoot transmetatarsal amputation is performed commonly to achieve limb salvage, but transmetatarsal amputations have a high rate of failure, requiring more proximal amputations. Few contemporary studies have examined the incidence of major amputation (transtibial or transfemoral) after transmetatarsal amputation. The goal of this study is to determine risk factors and outcomes for a more proximal amputation after forefoot amputation. METHODS: We queried the 2012 to 2016 database of the American College of Surgeons National Quality Improvement Program for patients undergoing a complete transmetatarsal amputation with wound closure by Current Procedural Terminology code...

A B S T R A C T Thrombotic events are a major cause of morbidity and mortality in cancer. While the association of venous thromboembolic events with cancer is well documented, in recent years arterial events (i.e. acute myocardial infarction and ischemic strokes) have also emerged as relatively common complications among cancer patients. In hematological malignancies incorporating a heterogeneous group of diseases, the prediction of thrombosis occurrence and/or recurrence is challenging, due to unique disease characteristics...

Perinatal stroke is a heterogeneous syndrome resulting from brain injury of vascular origin that occurs between 20 weeks of gestation and 28 days of postnatal life. The incidence of perinatal stroke is estimated to be between 1:1600 and 1:3000 live births (approximately 2500 children per year in the United States), though its actual incidence is difficult to estimate because it is likely underdiagnosed. Perinatal arterial ischemic stroke (PAIS) accounts for approximately 70% of cases of perinatal stroke. Cerebral sinovenous thrombosis, while less common, also accounts for a large proportion of the morbidity and mortality seen with perinatal stroke...

Advanced techniques in neuroimaging and genetics, as well as the publication of longer-term prognostic studies, have led to fetal neurology becoming an essential part of prenatal obstetric care. A multidisciplinary approach to providing prenatal counseling is now commonly used in most academic medical centers. Common conditions seen are ventriculomegaly, agenesis of the corpus callosum and other midline abnormalities, and posterior fossa anomalies. The prognosis frequently depends on the severity of the condition and the presence of other anomalies...

Bioethical conflicts in pregnancy are distinguished from those in other areas of medicine due to competing interests between mother and fetus because of their shared biology. Historically, prior to the advent of fetal therapy and advances in medical technology, the maternal-fetal complex was considered to be a single entity. With advances in medicine, treatment options can now be directed at both the mother and the fetus, and a duality has evolved in the maternal-fetal unit. Thus at some point during pregnancy, two individuals rather than just one are the responsibility of the physician...

Many neurologic diseases in women are influenced by the physiologic and hormonal changes of pregnancy, and pregnancy itself poses challenges in both treatment and evaluation of these conditions. Some diseases, such as epilepsy and multiple sclerosis, have a high enough prevalence in the young female population to support robust epidemiologic data while many other neurologic diseases, such as specific myopathies and muscular dystrophies, have a low prevalence, with data limited to case reports and small case series...

Intracerebral hemorrhage (ICH) is one of the most severe subtypes of stroke with high morbidity and mortality. Although a lot of drug discovery studies have been conducted, the drugs with satisfactory therapeutic effects for motor paralysis after ICH have yet to reach clinical application. Transient receptor potential vanilloid 4 (TRPV4), a Ca2+ -permeable cation channel and activated by hypoosmolarity and warm temperature, is expressed in various cell types. The present study investigated whether TRPV4 would participate in the brain damage in a mouse model of ICH...

Stroke ranks as the second leading cause of disability and death globally. Trigger receptors expressed on myeloid cells (TREM) -1 are responsible for the activation of the innate immune response and also play a critical role in inflammation. In this study, we reported the contribution of TREM-1 after ischemic damage in a rat middle cerebral artery occlusion (MCAO) model. This study also demonstrated that TREM-1 expression was upregulated following cerebral infarction in rats. TREM-1 inhibition was determined using its selective inhibitor, LP17, which indicated a neuroprotective effect on cerebral infarction damage...

BACKGROUND: Direct cannulation of the innominate artery for selective antegrade cerebral perfusion has been shown to be safe in elective proximal aortic reconstructions. We sought to evaluate the safety of this technique in acute aortic dissection. METHODS: A multi-institutional retrospective review was undertaken of patients who underwent proximal aortic reconstruction for Stanford type A dissection between 2006 and 2016. Those patients who had direct innominate artery cannulation for selective antegrade cerebral perfusion were selected for analysis...

BACKGROUND: Primary aldosteronism (PA) increases the risk of cardiovascular morbidity, including stroke, coronary artery disease, atrial fibrillation, and heart failure. The relationship between primary aldosteronism and aortic dissection has rarely been reported. We report a case of aortic dissection caused by secondary hypertension from PA and review similar cases in the literature. CASE PRESENTATION: A 56-year-old woman with a history of surgery for aortic dissection presented for follow-up of hypertension and a left adrenal mass...

BACKGROUND: While single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is a well-established noninvasive procedure for the evaluation of patients with coronary artery disease (CAD), it is unable to detect the presence of, or underestimates the extent of CAD in certain patients. We aimed to show that a bio-impedance device can detect early post-stress changes in several hemodynamic parameters, thereby serving as a potential marker for the presence of significant ischemia...

Acquired genetic mutations in hematopoietic stem or progenitor cells can lead to clonal expansion and imbalanced blood cell production. Clonal hematopoiesis is exceptionally common with human aging, confers a risk of evolution to overt hematologic malignancy, and also increases all-cause mortality and the risk of cardiovascular disease. The degree of risk depends on the specific mutation, number of mutations, mutant allele burden, and concomitant non-genetic risk factors (e.g., hypertension or cigarette smoking)...
