Carotid artery disease (CAD) is a common cause of ischemic stroke with high rates of recurrence. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are highly recommended for the secondary prevention of symptomatic CAD during the first 14 days following the index event of transient ischemic attack or minor stroke. CEA or CAS may also be offered in selected cases with severe asymptomatic stenosis. Herein, we review the utility of neurosonology in the diagnosis and pre-/peri-interventional assessment of CAD patients who undergo carotid revascularization procedures...

PURPOSE: There is currently a lack of universally accepted criteria for gastrointestinal (GI) failure or dysfunction in critical care. Also, the clinical assessment of intestinal function is notoriously difficult and thus often goes unrecognized, contributing to poor outcomes. A recent grading system has been proposed to define acute gastrointestinal injury (AGI) in conjunction with other organ function scores (e.g., SOFA). Ultrasonography has become widely accepted as a diagnostic tool for GI problems and pathology...

We evaluated the role of vertebral artery extracranial color-coded duplex sonography (VAECCS) in predicting vertebrobasilar stroke in consecutive patients presenting to the emergency department with vertigo of suspected ischemic origin. The final diagnosis was established by a panel of experts consisting of an emergency physician, a neurologist, and an otoneurologist. Vertebrobasilar stroke was diagnosed when an acute brain ischemic lesion congruent with symptoms was detected by neuroimaging during the index visit or a stroke was diagnosed within a 3-mo period after emergency department presentation...

BACKGROUND: Preeclampsia is associated with greater narrowing of the airway than normal pregnancy, but it is not known if these changes worsen during labor and delivery. The aim of the study was to evaluate the airway during and after labor in women with or without preeclampsia. METHODS: Twenty-five normal and 25 severely preeclamptic pregnant women in early labor were recruited in this single-center, prospective, case-control study. Airway assessment was performed (a) before active labor (b) within one hour of delivery and (c) 24-48 h postpartum...

OBJECTIVES: To determine whether sonographic versions of physical examination techniques can accurately identify splenomegaly, Castell's method (Ann Intern Med 1967; 67:1265-1267), the sonographic Castell's method, spleen tip palpation, and the sonographic spleen tip technique were compared with reference measurements. METHODS: Two clinicians trained in bedside sonography patients recruited from an urban hematology clinic. Each patient was examined for splenomegaly using conventional percussion and palpation techniques (Castell's method and spleen tip palpation, respectively), as well as the sonographic versions of these maneuvers (sonographic Castell's method and sonographic spleen tip technique)...

Cerebrospinal fluid (CSF) flow is sensitive to many cerebral disorders. We aimed to develop a noninvasive bedside method to detect physiological and pathological CSF phenomena by measuring pulsation patterns of the third ventricle. By transcranial B-mode ultrasound, electrocardiography (ECG)-gated video loops of the third ventricle were acquired. "Speckle tracking" software was used to quantify the relative change of its width. We conducted measurements of nine cardiac cycles in 11 healthy subjects in sitting and in supine position during Valsalva maneuver to investigate the influence of an increased intracranial pressure on the relative deformation of the third ventricle...

In the early days of ultrasound, it was not a translational discipline. The heart was claimed by cardiologists, with others, such as gynaecologists, urologists and vascular surgeons claiming their part while the rest was given to radiologists. Only recently, ultrasound transgressed and crossed the usual borders between the different disciplines, such as emergency and critical care medicine. The advent of portable machines in the early 1980s, allowed the critical care physician to perform bedside ultrasound, and the development of whole body critical care ultrasound (CCUS) was born...

The so-called point-of-care ultrasound (POCUS) is of increasing importance for diagnostics and therapy control in intensive care medicine. Based on focused thorax sonography, echocardiography, and abdominal sonography, the most important working and differential diagnoses can be demonstrated or excluded depending on the leading symptom. Sonographic-based algorithms allow a structured evaluation especially of patients with the common leading symptoms dyspnea and thoracic pain.

REVIEW
Vincent Issac Lau, Robert Thomas Arntfield
In the unconscious patient, there is a diagnostic void between the neurologic physical exam, and more invasive, costly and potentially harmful investigations. Transcranial color-coded sonography and two-dimensional transcranial Doppler imaging of the brain have the potential to be a middle ground to bridge this gap for certain diagnoses. With the increasing availability of point-of-care ultrasound devices, coupled with the need for rapid diagnosis of deteriorating neurologic patients, intensivists may be trained to perform point-of-care transcranial Doppler at the bedside...

OBJECTIVE: The incidence of chronic Subdural hematoma (cSDH) is increasing and its rate of recurrence varies from 5 to 33%. A postoperative brain midline-shift (MLS) on computed tomography (CT) equal or larger than 5mm is a risk factor for recurrence. Transcranial color-coded duplex sonography (TCCDS) is a noninvasive bedside reproducible technique useful to detect MLS. The aim of our study was to compare in patients affected by cSDH, the values of MLS obtained pre- and post-operatively by TCCDS and brain CT...

BACKGROUND: Development of hydrocephalus can occur after subarachnoid hemorrhage (SAH). Typically, it is diagnosed with computed tomography, CT, scan. However, transcranial sonography (TCS) can be used particularly in patients with craniotomy which removes the acoustic interference of the skull and allows a closer up visualization of brain structures through the skin. CASE PRESENTATION: We report a 73-year-old woman who was hospitalized for SAH and developed acute hydrocephalus requiring an external ventricular drain (EVD)...

BACKGROUND Lienalis steal syndrome is a rare complication after orthotopic liver transplantation leading to severe complications. Routine duplex sonography allows early and safe detection of lienalis steal syndrome and secondarily helps to monitor the outcome by evaluating the hemodynamics. MATERIAL AND METHODS This analysis included eight patients who after orthotopic liver transplantation needed splenic artery embolization due to lienalis steal syndrome. Lienalis steal syndrome was assumed in case of elevated transaminases, bilirubinemia or persistent ascites, and the absence of further pathologies...

REVIEW
Niraj Sinha, Sam Parnia
PURPOSE OF REVIEW: Of the approximately 350,000 out-of-hospital, and 750,000 after in-hospital cardiac arrest (CA) events in the US annually approximately 5-9% and 20% respectively may achieve return of spontaneous circulation (ROSC) after attempted cardiopulmonary resuscitation (CPR). Up to 2/3 of these initial survivors may go on die in the subsequent 24-72 hours after ROSC due to a combination of (1) on-going cerebral injury, (2) myocardial dysfunction and (3) massive systemic inflammatory response...

The use of B- and M-mode sonography for detection of pneumothorax has been well described and studied. It is now widely incorporated by sonographers, emergency physicians, trauma surgeons, radiologists, and critical care specialists worldwide. Lung sonography can be performed rapidly at the bedside or in the prehospital setting. It is more sensitive, specific, and accurate than plain chest radiography. The use of color and power Doppler sonography as an adjunct to B- and M-mode imaging for detection of pneumothorax has been described in a small number of studies and case reports but is much less widely known or used...

Objective: Pulmonary aspiration of the gastric contents is one of the most feared complications in anesthesia. Its prevention depends on preoperative fasting as well as identification of risky patients. A reliable diagnostic tool to assess gastric volume is currently lacking. The aim of this study performed on volunteers was to evaluate the feasibility of ultrasonography to identify qualitative and quantitative gastric content. Method: A standardized gastric scanning protocol was applied on 67 healthy volunteers to assess the gastric antrum in four different situations: fasting, after ingesting clear fluid, milk and a solid meal...

PURPOSE: Nasogastric feeding tube is routinely positioned in intensive care units. The complications of misplacement are rare but very dangerous for the patients. The aim of this study is to estimate the diagnostic accuracy of this new technique, 4-point ultrasonography to confirm nasogastric tube placement in intensive care. METHODS: One hundred fourteen critical ill patients monitored in ICU were included. The intensivist provided in real time to perform the exam in four steps: sonography from either the right or left side of the patient's neck to visualize the esophagus, sonography of epigastrium to confirm the passage through the esophagogastric junction and the positioning in antrum, sonography of the fundus...
