Background: Point-of-care ultrasound (POCUS) has been reported as a valuable tool for bedside diagnoses of abdominal Aortic Aneurysms (AAA). However, no data exist regarding POCUS in measuring follow-up AAA diameter studies in patients with existing AAAs. The purpose of this study was to determine the variability of aortic measurements performed by a non-physician using POCUS vs standard of care (SOC) measurements by a registered vascular technologist or an abdominal/pelvic CT scan.

Point-of-care ultrasound (POCUS) improves both the sensitivity and specificity with which clinicians can make a variety of diagnoses at the bedside from abdominal aortic aneurysm to kidney stones. In outpatient clinics, urgent care centers, and emergency departments, where ultrasound imaging may be delayed by hours or even days, the use of POCUS can be very helpful. We believe that POCUS facilitates both the triage of patients and provides diagnostic information quickly. Read More

Naval Hospital Jacksonville, Jacksonville, FL, USA.

Point-of-care ultrasonography (POCUS) is performed by a physician at the bedside and is standard practice in obstetric, emergency, and musculoskeletal medicine. When compared with formal sonography, POCUS is equivalent in screening for abdominal aortic aneurysm and as accurate in diagnosing deep venous thrombosis. POCUS has high accuracy for diagnosing pneumonia and detecting acute decompensated heart failure but is less accurate than computed tomography for identifying pulmonary embolism. Read More

Patients who present to the emergency department (ED) with aortic emergencies can be some of the highest acuity patients that we manage. Ultrasonography performed at the bedside is traditionally considered to be a screening test that is especially useful in the unstable patient. Computed tomography (CT) with angiography is the imaging modality of choice to confirm the diagnosis and plan the management of abdominal aortic aneurysm (AAA), as an ultrasound is generally thought not to provide the clinician with sufficient anatomical information.

A 79-year-old ASA class 3 patient scheduled for outpatient testing secondary to prostate cancer, was found to have a previously unknown 10-cm abdominal aortic aneurysm (AAA) causing acute renal insufficiency and hydronephrosis, requiring prompt surgical intervention. The patient was instructed to return to the hospital for further evaluation of the AAA and emergent ureteral stent placement. During the preanesthetic examination, the patient revealed he had eaten a small amount of food before returning to the hospital, placing him at increased risk of pulmonary aspiration. Read More

Point-of-care ultrasonography, which is performed at the bedside by physicians who are not specialists in imaging, has become possible thanks to recent technological advances that have allowed for a device with greater portability while maintaining image quality. The increasing use of point-of-care ultrasonography in different specialties has made it possible to expand physical examinations, make timely decisions about the patients and allows the performance of safer medical procedures. In this review, three cases from our experience are presented that highlight the use of point-of-care ultrasonography by clinicians. Read More

Faculty of Medicine, University of Ottawa, Ottawa, ON, Canada; Division of Vascular and Endovascular Surgery, The Ottawa Hospital, Ottawa, ON, Canada.

Background: The use of point-of-care ultrasound (POCUS) has become increasingly prevalent in medical practice as a non-invasive tool for focused bedside diagnosis. Consequently, some medical schools have begun implementing POCUS training as a standard in their medical school curriculum. The feasability and value of introducing POCUS training at the medical student level to screen for abdominal aortic aneurysms (AAA) should be explored. Read More

Department of Diagnostic Radiology, Changi General Hospital, Singapore.

A 77-year-old man presented with acute-onset severe chest pain radiating to the back and elevated blood pressure. Multiphasic computed tomography of the aorta revealed an intimal tear in the descending thoracic aorta which extended both retrograde to the aortic root and antegrade to the infra-renal abdominal aorta. The initial impression, that the images showed a Stanford type B aortic dissection, was because the portion of the false lumen that extended beyond the aortic arch remained unopacified even on delayed phases, making it challenging to assess the extent of the dissection flap.

Contrast-enhanced ultrasound (CEUS) is increasingly being used to evaluate patients with known or suspected atherosclerosis. The administration of a microbubble contrast agent in conjunction with ultrasound results in an improved image quality and provides information that cannot be assessed with standard B-mode ultrasound. CEUS is a high-resolution, noninvasive imaging modality, which is safe and may benefit patients with coronary, carotid, or aortic atherosclerosis. Read More

Ultrasound is an easy to learn and highly efficient diagnostic tool to complete the clinical examination and improve bedside decision-making. In the trauma room, surgeons are often required to make a quick decision as to whether or not a patient needs an emergency intervention or whether further diagnostics are required. For this reason, education of surgeons in performing focused emergency ultrasound is pivotal. Read More

Department of Emergency Medicine, University of Ottawa, Ottawa, Canada.

Aortic dissection (AD) is one of the most challenging diagnoses in emergency medicine. This is due, in part, to its variable presentation, ranging from abrupt tearing chest pain in a hemodynamically unstable patient to back pain in a stable patient, as well as its high mortality rates. (1) With the expanding role of ultrasound (U/S) performed by emergency physicians, it is possible to make the diagnosis of AD at the bedside before any other imaging modality has been accessed.

Cardiology Department, AP-HP, Bichat Hospital, 46 rue Henri Huchard, 75018 Paris, France.

Aims: Patients with acute myocardial infarction (AMI) represent a high-risk population in which screening for abdominal aortic aneurysm (AAA) is recommended but only occasionally performed. Transthoracic echocardiography (TTE) may offer the unique opportunity to evaluate the cardiac function and to screen for AAA during the same examination. We aimed to evaluate the feasibility of AAA screening at bedside using a portable cardiac ultrasound (US) echo machine and to determine the prevalence of AAA in population with AMI. Read More

Echocardiography 2012 Mar 8;29(3):285-90. Epub 2011 Nov 8.

Echocardiography Department, University of Bordeaux, Pessac, France.

Background: Ultraminiaturization of echographic systems extraordinarily provides the image "within" the clinical examination. Abdominal aorta aneurysm (AAA) diagnosis based on conventional evaluation with a dedicated operator and ultrasound machine is still controversial due to the lack of evidence of the proposed management and guidelines' cost-effectiveness. We hypothesized that less expensive ultraportable devices could identify AAA with the same level of accuracy as conventional approaches. Read More
