UP TO 40% of all ischemic strokes are considered cryptogenic, implying a stroke without a definitive etiology.1,2 With a dearth of evidence-guided treatment strategies, the literature surrounding cryptogenic stroke is highly variable and not well-standardized. Even though existing guidelines do not specify the exact testing required, the cryptogenic stroke evaluation includes a variety of imaging modalities (eg, echocardiography, angiography, magnetic resonance imaging, carotid ultrasound) and laboratory investigations (eg, genetic testing, hypercoagulable disorder panels, erythrocyte sedimentation rate).

Editor ’s PerspectiveWhat We Already Know about This TopicCardiac output is an independent regulator of cerebral blood flow in healthy awake humansThe relationship between cardiac output and cerebral blood flow in anesthetized patients undergoing laparoscopy has not been previously characterizedWhat This Article Tells Us That Is NewAt steady-state depth of anesthesia, in patients undergoing laparoscopic cholecystectomy, creation of pneumoperitoneum decreased cardiac output and internal carotid artery blood flow while mean arterial pressure and end-tidal carbon dioxide levels remained unchangedBackground Little is kno...

A number of awake patients undergoing carotid endarterectomy (CEA) present from test clamp neurological deficits (NDs) during the procedure. Current guidelines advocate tighter Doppler ultrasound (DUS) surveillance in these patients because of probable higher likelihood of hemodynamic stroke (class 1 grade C), although evidence is lacking regarding benefit. The aim for the study is the assumption that patients who present ND have a higher risk of developing a complete stroke if the ipsilateral carotid artery becomes occluded, and for this reason, surveillance over restenosis of endarterectomy in this group is justifiable; ...

Editor ’s PerspectiveWhat We Already Know about This TopicSeveral ultrasound parameters for assessing fluid responsiveness have been describedTransfontanelle ultrasound can be easily used in small children undergoing surgery, and the anterior fontanelle is an optimal site for Doppler examination of the internal carotid arteryPrevious studies have identified a relationship between fluid responsiveness and respiratory variation in the arterial blood flow peak velocity in the ascending aorta and/or the proximal branches of the aortaWhat This Article Tells Us That Is NewIn infants having cardiac surgery, the respiratory ...

CARDIAC tamponade can be difficult to diagnose because clinical and electrocardiogram findings have low sensitivity and specificity. Intubation and positive pressure ventilation during unrecognized tamponade can lead to hemodynamic instability from decreased venous return and increased right ventricular afterload, compromising right ventricular stroke volume. Focused cardiac ultrasound can rapidly demonstrate sensitive and specific findings of tamponade.1 The increased availability, noninvasiveness, portability, and rapid acquisition of images have made focused cardiac ultrasound an indispensable perioperative tool.2,3

The largest available study on the subject, the GALA trial, has not shown any difference in patient's outcome – incidence of stroke and 30-day-mortality postsurgery. However, increasing evidence favors regional anesthesia as an independent factor of reduced morbidity after CEA. The advantages a...
