Acute lower extremity ischemia from septic emboli is a surgical emergency. Timely diagnosis and management are critical to improve patient outcome. However, traditional diagnostic modalities such as intraoperative angiogram are time-consuming, require special equipment and personnel, and introduce contrast exposure for critically ill patients. There are limited reports of utilization of point-of-care ultrasound to detect peripheral septic emboli. We present a case where femoral occlusive septic emboli were identified by point-of-care ultrasound after mitral valve replacement...

The diagnosis of aortic dissection (AD) is sometimes difficult within the limited time window of recombinant tissue plasminogen activator (tPA) for ischemic stroke (IS). A 60-year-old man developed sudden left hemiparesis due to IS. During tPA infusion, his blood pressure dropped and consciousness declined. After transfer to our hospital, carotid duplex ultrasonography led to a diagnosis of AD. Emergency surgery was postponed because of the risk of hemorrhagic transformation. The patient successfully underwent aortic surgery on day 5 and was discharged with a remarkable improvement in his symptoms...

INTRODUCTION: Rapidly enlarging mammary tumors, including invasive breast tumors, are clinically rare. Invasive micropapillary carcinoma (IMPC) of the breast is known to have aggressive behavior and poor clinical course compared to invasive ductal carcinoma. CASE PRESENTATION: An 87-year-old woman presented with a rapidly enlarging tumor of the right breast over the course of 3 weeks. Ultrasonography and computed tomography of the chest revealed a giant tumor located on the right chest wall, with heterogeneous parenchymal components and several cystic lesions...

We present a 4-week-old neonate with acute onset of bloody stools and abdominal distention. Point-of-care ultrasound performed in the emergency department allowed for rapid diagnosis of a large amount of free intra-abdominal fluid, which together with the physical findings, prompted emergent operative exploration revealing chylous ascites. Although no areas of active volvulus were identified intraoperatively, findings in the case were suggestive of small bowel volvulus and deemed as the most likely etiology for this patient's presentation...

Gynecologic emergencies include various diseases that result from adnexal and uterine disorders. Adnexal disorders may be classified into the following three categories: (a) disorders that cause hemorrhage (hemorrhagic ovarian cysts and ectopic pregnancies); (b) disorders related to adnexal tumors (adnexal torsion and rupture of ovarian tumors); and (c) disorders related to pelvic inflammatory disease, such as tubo-ovarian abscesses. Unusual adnexal torsion, such as massive ovarian edema, isolated fallopian tube torsion, and paraovarian cyst torsion, has also been described...

Although abdominal pain is a common presentation in emergency departments, rectus sheath hematoma (RSH) is among the rarest diagnosis. Here we present 2 cases of RSH likely caused by coughing due to upper respiratory tract infection. The two described cases were diagnosed by bedside ultrasonography and confirmed as RSH by computed tomography. Review of patient history and use of ultrasonography are important to avoid misdiagnosisof RSH.

BACKGROUND: Kidney transplantation is the treatment of choice for patients with end-stage renal disease. The standard surgery uses the recipient's iliac vessels for vascular anastomosis. Thrombosis and/or stenosis of the iliac vein, which are possible complications of multiple vascular access points for dialysis, can be detected intraoperatively, constituting a surgical challenge. An infrequently reported option is the use of the gonadal vein. OBJECTIVES: This study aims to evaluate the outcomes of venous anastomosis in the gonadal vein in patients with iliac vein thrombosis and/or stenosis submitted to kidney transplantation...

INTRODUCTION: Gallbladder torsion is mainly associated with a floating gallbladder. From an anatomical perspective, laparoscopic cholecystectomy is a more optimal treatment than open cholecystectomy. PRESENTATION OF CASE: An 84-year-old woman visited the Onomichi General Hospital because of progressive pain in the right upper quadrant of her abdomen. Physical examination revealed a positive Murphy sign and peritoneal irritation. Laboratory data demonstrated that inflammatory marker levels were increased...

Radiation therapy has emerged as a useful alternative therapy for patients with early-stage, non-resectable lung cancer. In patients whose malignancies are difficult to localize on computed tomography imaging, such therapy becomes difficult. Fiducial markers are frequently placed in peripheral pulmonary lesions to assist radiation therapy. Although placement of markers under linear endobronchial ultrasonography within mediastinal and hilar lymph nodes has been reported, no strategy has been described to assist radiotherapy of purely endobronchial tumors...

Ultrasound contrast agents (UCA) represented by gas-filled microbubble, can provide simultaneous and co-localized enhancement on image contrast to help disease diagnosis by highlighting tissue borders. Nowadays, Some UCAs (e.g. Levovist®, Optison®, Definity®, and Sonovue®) are commercially available, and have been clinically utilized for enhanced ultrasonography in the US, Canada, Europe, Asia and so on. However, their large diameters (1~10 μm) mainly hinder more precise and deeper applications in the imaging of capillary-abundant organs or tissues (e...

Juvenile idiopathic arthritis (JIA) and osteoarticular infection can cause nonspecific articular and periarticular complaints in children. Although contrast material-enhanced magnetic resonance imaging is the reference standard imaging modality, musculoskeletal ultrasonography (US) is emerging as an important adjunct imaging modality that can provide valuable information relatively quickly without use of radiation or the need for sedation. However, diagnostic accuracy requires a systemic approach, familiarity with various US techniques, and an understanding of maturation-related changes...

In their introduction, Gungor et al described ultrasound as a technique for evaluation of patients with low prior probability of acute appendicitis. This testing protocol for appendicitis is being proposed to challenge and perhaps replace the current standard of care for imaging, CT scanning. Specificity of CT scanning is reported in the range of 92-98% and CT is generally felt to be more accurate than ultrasonography The finding of 95.8% specificity for their method appears competitive and may be arithmetically correct but is seriously flawed...

We describe the case of a 55-year old women admitted at night to the emergency department (ED), complaining for acute abdominal pain lasting for nearly 5 hours. A first blood testing, performed immediately after admission, revealed mild anaemia. A second blood sample, drawn two hours after admission, revealed a considerable decrease of haemoglobin, haematocrit, total white blood cell and platelet counts (between 10-15% reduction). Abdominal ultrasonography was normal and the patient had no signs or symptoms of internal or external haemorrhage...

INTRODUCTION: There is a variety of tools being used in clinical practice for the prediction of weaning success from mechanical ventilation. However, their diagnostic performances are less than satisfactory. The purpose of this study is to investigate the value of serial changes in diaphragm function measured by ultrasound during the spontaneous breathing trial (SBT) as a weaning predictor. METHODS AND ANALYSIS: This is a prospective observational study conducted in a 10-bed medical emergency intensive care unit (EICU) in a university-affiliated hospital...
