Insula and sensory insular cortex and somatosensory control in patients with insular stroke
ConclusionOur data allow the conclusion that the posterior IC may represent the major region responsible for encoding warm and cold perception in the brain. To what extent focal IC lesions may also impair pain processing or induce post‐stroke pain has to be addressed in future studies including more patients.

Noninvasive pulse pressure variation and stroke volume variation to predict fluid responsiveness at multiple thresholds: a prospective observational study
Conclusion Noninvasive PPV and SVV measurements allow an acceptable FR prediction, although the reliability of both variables is dependent on the intended increase in SVI, which improves substantially with concomitant smaller grey zones at higher ↑SVI thresholds.

Influence of tidal volume on pulse pressure variation and stroke volume variation during experimental intra-abdominal hypertension
Conclusion: IAH induction in non-hypovolemic subjects significantly increased SVV and PPV with the three tested V T , but the magnitude of that change was higher with larger V T . This observation reveals the dependence of functional hemodynamic markers on intrathoracic as well intra-abdominal pressures, in addition to volemic status. Also, PPV and SVV were unable to predict fluid responsiveness after IAH induction. Future studies should take into consideration these findings when exploring relationships between dynamic preload indicators and fluid responsiveness during IAH.

Measurement of cardiac index and stroke volume using electrical cardiometry before and after administration of adenosine in a 6-year-old patient with supraventricular tachycardia
We report the case of a 6-year-old boy who developed a supraventricular tachycardia during an upper endoscopy while under general anesthesia. A noninvasive electrical cardiometry device was applied to the patient, and cardiac index and stroke volume were measured before and after the administration of adenosine. Cardiac index fell 41% (P

Effect of isoflurane post-treatment on tPA-exaggerated brain injury in a rat ischemic stroke model.
CONCLUSIONS: Isoflurane post-treatment may mitigate infarction volume and intracranial hemorrhage in tPA-exaggerated brain injury. Our findings provide an encouraging novel approach for enhancing clinical outcomes in tPA-exaggerated brain injury. PMID: 26045932 [PubMed]

Anesthetic considerations for renal transplant surgery in patients with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes syndrome: a case report
Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes syndrome is a progressive syndrome with variable involvement of multiple-organ systems. These patients require special consideration for preoperative optimization, intraoperative management, and postoperative care. The medical literature regarding perioperative management of these patients relies heavily on case reports. Here we present a novel experience providing care for a patient with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes syndrome who underwent renal transplantation for focal segmental glomerulo...

Anesthesia for Endovascular Approaches to Acute Ischemic Stroke
Publication date: September 2016 Source:Anesthesiology Clinics, Volume 34, Issue 3 Author(s): Rafi Avitsian, Sandra B. MachadoTeaser Involvement of the Anesthesiologist in the early stages of care for acute ischemic stroke patient undergoing endovascular treatment is essential. Anesthetic management includes the anesthetic technique (general anesthesia vs sedation), a matter of much debate and an area in need of well-designed prospective studies. The large numbers of confounding factors make the design of such studies a difficult process. A universally agreed point in the endovascular management of acute ischemic stroke i...

Perioperative stroke following transurethral resection of prostate: high index of suspicion and stabilization of physiological parameters can save lives.
We report a case of a 72 year old hypertensive male who developed severe hypertension followed by neurological deterioration in the immediate postoperative period after transurethral resection of prostate. While arterial blood gas and laboratory tests excluded transurethral resection of prostate syndrome or any other metabolic cause, reduction of blood pressure failed to ameliorate the symptoms. A cranial CT done 4hours after the onset of neurological symptoms revealed bilateral gangliocapsular and right thalamic infarcts. Oral aspirin was advised to prevent early recurrent stroke. Supportive treatment and mechanical venti...

Stroke After Transcatheter Aortic Valve Replacement: Incidence, Definitions, Etiologies and Management Options
Neurologic complications after transcatheter aortic valve replacement are devastating. The etiologies of stroke in this setting are best addressed in an integrated fashion during each phase of the perioperative pathway. The conduct of this triphasic approach will continue to be refined to reduce the stroke risks even further, given the major focus on aspects such as embolic protection devices and valve thrombosis. This neurologic focus in transcatheter aortic valve replacement has transformed the investigational approach to neurologic events in cardiovascular clinical trials, resulting in novel guidelines for the diagnosis...

Anesthetic management of endovascular treatment for acute ischemic stroke: Influences on outcome and complications
ConclusionsGeneral anesthesia and conscious sedation are both safe alternatives for anesthetic management of patients submitted to endovascular thrombectomy. No anesthetic management is universally recommended and hopefully the ongoing randomized clinical trials will shed some light on the best approach; meanwhile, the choice of anesthesia should be based on the patient's individual characteristics. Regarding neuroprotection, hemodynamic stability is currently the most important strategy, as no pharmacological method has been proven effective in humans.ResumoJustificativa e objetivosO uso emergente de terapias endovascular...

Endovascular thrombectomy in acute ischemic stroke: new treatment guide
Purpose of review Recent randomized clinical trials (RCTs) have demonstrated strong efficacy of endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) from large vessel occlusions (LVO). SIESTA, AnSTROKE, GOLIATH showed no deleterious effects of general anesthesia on patient outcome after EVT compared with conscious sedation. DAWN and DEFUSE 3 are extending the time window for EVT up to 24 h in carefully selected patients. This review discusses the current literature on the rapidly expanding subject of endovascular stroke therapy and optimal anesthetic management. Recent findings Recent retrospective studie...

Endovascular treatment of acute ischaemic stroke under conscious sedation: Predictors of poor outcomes
Conclusion: The outcome of patients who underwent endovascular treatment of AIS under CS depends on the mTICI score, NIHSS score and history of previous TIA.
