HISTORY AND ADMISSION FINDINGS: We report on a 58-year-old male patient with abdominal and right-sided flank pain, who presented with the picture of an acute abdominal emergency. INVESTIGATIONS: Laboratory tests revealed evidence of an inflammation and a hematuria. In the Doppler duplex ultrasound and computed tomography, chronic idiopathic periaortitis was diagnosed. The inflammatory-fibrosing disease resulted in urine retention and rupture of the fornix of the right kidney...

In Italy the vast majority of TIA and minor strokes are seen in the A&E. Early diagnosis and management of TIA and minor stroke in this setting is habitually difficult and often lead to cost-ineffective hospital admissions. We set up an ultra-rapid TIA service run by neurovascular physicians based on early specialist assessment and ultrasound vascular imaging. We audit the clinical effectiveness and feasibility of the service and the impact of this service on TIA and minor strokes hospital admissions. We compared the rate of TIA and minor stroke admissions/discharges in the year before (T0) and in the year during which the TIA service was operating (T1)...

Acute aortic syndrome is a relatively recent clinical entity. Non-invasive imaging methods, such as computed tomography and transesophageal echocardiography, have contributed significantly to the diagnosis of variant forms of classic aortic dissection, which have become important disease entities in acute aortic syndrome. Imaging findings may result in risk stratification and application of different treatment options, providing a rational approach to achieve a better outcome of this syndrome. This review will focus on the imaging characteristics of two important variant forms of classic aortic dissection, intramural hematoma and incomplete dissection, and the role of imaging methods in the evaluation of differences in the hemodynamic status of false lumens that contributes to patient prognosis...

PURPOSE: Assessment of volume status remains a challenge in critical care. Our purpose was to determine if Doppler waveform analysis of carotid artery blood flow correlates with changes in volume status. MATERIALS AND METHODS: Dehydrated patients receiving an intravenous fluid bolus were enrolled with exclusions including age less than 18 years, pregnancy, vasopressor administration, or atrial fibrillation. Ultrasound examination with Doppler analysis of the carotid artery was performed with measurements taken to calculate corrected flow time (FTc)...

Color Doppler ultrasonography (CDUS) is a readily available, inexpensive and noninvasive method, which has improved the survival of native arteriovenous fistula (AVF) by increasing the early diagnosis of complications. Although angiography has been currently considered as the gold standard for imaging of vascular access abnormalities, CDUS may be superior in some aspects, since it provides information both on the morphology and on the function of vascular access and it is the only tool directly available to the nephrologist...

Over the past decade, emergency and critical care physicians have been empowered with the ability to use bedside ultrasonography to assist in the evaluation and management of a variety of emergent conditions. Today a single health care provider at the bedside with Duplex ultrasound technology can evaluate peripheral vascular calamities that once required significant time and a variety of health care personnel for the diagnosis. This article highlights peripheral thromboembolic disease, aneurysm, pseudoaneurysm, and arterial occlusion in the acute care setting...

Acute vascular emergencies can arise from direct traumatic injury to the vessel or be spontaneous (non-traumatic).The vascular injuries can also be divided into two categories: arteial injury and venous injury.Most of them are life-treatening emergencies, sice they may cause an important ipovolemic shock or severe ischemia in their end organ and require prompt diagnosis and treatment.In the different clinical scenarios, the correct diagnostic approach to vascular injuries isn't firmly established and advantages of one imaging technique over the other are not obvious...
