INTRODUCTION: The focused assessment with sonography in trauma (FAST) exam is a critical diagnostic test for intraperitoneal free fluid (FF). Current teaching is that fluid accumulates first in Morison's pouch. The goal of this study was to evaluate the "sub-quadrants" of traditional FAST views to determine the most sensitive areas for FF accumulation. METHODS: We analyzed a retrospective cohort of all adult trauma patients who had a recorded FAST exam by emergency physicians at a Level I trauma center from January 2012 - June 2013...

We evaluated the use of vaginal implant transmitters (VITs) as a means of detecting, capturing, and radio collaring Rocky Mountain bighorn sheep ( Ovis canadensis canadensis) lambs to estimate survival and to facilitate carcass recovery to assess causes of mortality. We focused on one of several bighorn herds in Colorado, USA, suffering from depressed recruitment that was not preceded by a classic all-age die-off. We captured, radio-collared, diagnosed pregnancy by ultrasound examination, and inserted VITs into 15 pregnant ewes from a herd residing near Granite, Colorado...

Postoperative spindle cell nodule (PSCN) is a very rare pathologic complication that can occur in association with a recent core needle biopsy, surgery, or trauma. Cases of PSCN have been reported in the lower genitourinary tract, endometrium, and thyroid but are rare in the breast. Herein, we report an ultrasound-guided biopsy-proven PSCN after ultrasound-guided vacuum-assisted excision in the breast.

This paper presents the latest in vivo findings of a novel vascular coupling system. Vascular anastomosis is a common procedure in reconstructive surgeries and traditional hand suturing is very time consuming. The vascular coupling system described herein was designed to be used on arteries for a rapid and error-free anastomosis. The system consists of an engaging ring made from high density polyethylene using computer numerical control machining and a back ring made from polymethylmethacrylate using laser cutting...

A 28-week-old fetus was detected to have a single left atrial mass in prenatal ultrasound. Postnatal echocardiography showed an aneurysm between the anterior mitral leaflet and aortic valve, to the left of atrioventricular junction and communicating with the left ventricle through a narrow mouth. It probably originated from the mitral-aortic intervalvular fibrous tissue and an inherent weakness at this site might be the cause. Reported cases of pseudoaneurysm of mitral-aortic intervalvular fibrosa and subvalvular ventricular aneurysms seen following infective endocarditis, surgery, or trauma seem to have a similar anatomical background...

Purpose Patients suffering from severe blunt abdominal trauma are challenging because of their need for accurate diagnostic imaging and fast therapeutic action. Whole-body computed tomography (WBCT) is highly sensitive and represents the gold standard in the trauma room diagnostic setting. The aim of our study was to investigate the impact and therapy relevance of abdominal follow-up sonography (AFS) as part of the tertiary trauma survey (TTS) in patients without abdominal parenchymal organ lesions or free abdominal fluid in initial WBCT...

Hematomas and soft tissue sarcomas can be difficult to differentiate clinically, even with the addition of traditional imaging modalities. There are several case reports of sarcomas being misdiagnosed as hematomas, most commonly with a history of mild trauma. In this case report, we described a sarcoma initially misinterpreted as a hematoma on ultrasound. Key clinical features and sonographic findings that may assist clinicians using point-of-care ultrasound to correctly differentiate sarcomas from hematomas are reviewed...

AIMS AND OBJECTIVES: Splenic dimension of >12 cm on coronal plane on ultrasound is considered to represent splenomegaly. We sought to estimate the accuracy of similar coronal oblique length of spleen on CT in identifying splenomegaly by comparing it with CT splenic index. We also sought to establish the splenic width, craniocaudal dimension (CC), thickness, and coronal oblique length in both normal and splenomegaly groups. MATERIALS AND METHODS: 319 consecutive patients undergoing CT abdomen were included in the study and measurements of width (W), CC, thickness (T), and coronal oblique length (L) made...

BACKGROUND Popliteal fossa pseudoaneurysms as a result of trauma are not uncommon. However, spontaneous pseudoaneurysms as a result of non-traumatic rupture of posterior tibial artery (PTA), anterior tibial artery (ATA), or tibioperoneal trunk (TPT) artery segment are extremely rare. We report a case of spontaneous popliteal fossa pseudoaneurysm resulting from spontaneous avulsion of the ATA and transection of the TPT. Despite a thorough workup, no underlying associated disease was found. The extreme rarity of this disease presentation prompted us to report this case...

INTRODUCTION: Damage to the pelvic floor during vaginal childbirth is common, and may take the form of levator avulsion or irreversible over-distention of the levator hiatus (microtrauma). Such trauma is a major risk factor for pelvic organ prolapse later in life. In this study we aimed to identify intrapartum risk factors for levator trauma. MATERIAL AND METHODS: This is a retrospective analysis of data obtained in two perinatal studies on primiparous women. Between 2005 and 2014, 1148 patients carrying an uncomplicated singleton pregnancy in the late third trimester were seen for 4D pelvic floor ultrasound and an interview...

INTRODUCTION: The first formal orientation program for incoming emergency medicine (EM) residents was started in 1976. The last attempt to describe the nature of orientation programs was by Brillman in 1995. Now almost all residencies offer orientation to incoming residents, but little is known about the curricular content or structure of these programs. The purpose of this project was to describe the current composition and purpose of EM resident orientation programs in the United States...

Fang Chen, Jia Liu, Hongen Liao
In endovascular catheter interventions, the determination of the three-dimensional (3D) catheter shape can increase navigation information and help reduce trauma. This study describes a shape determination method for a flexible interventional catheter using ultrasound scanning and a two-step particle filter without X-ray fluoroscopy. First, we propose a multi-feature, multi-template particle filter algorithm for accurate catheter tracking from ultrasound images. Second, we model the mechanical behavior of the catheter and apply a particle filter shape optimization algorithm to refine the results from the first step...

Epiaortic ultrasound is an imaging modality that is commonly used to evaluate the ascending aorta for atheroma and other mural lesions during elective cardiac surgery. Its use in contained aortic rupture has not been established. We present a case of thoracic trauma with contained pseudoaneurysm of the ascending aorta. At operation, the precise location of the aortic tear could not be identified by visual inspection, manual palpation, or transesophageal echocardiography. Epiaortic ultrasound was employed and the aortic defect was identified and successfully repaired...
