BACKGROUND: Diagnosis and management of patients presenting with acute dyspnea is one of the major challenges for physicians in emergency department (ED). A correct diagnosis is frequently delayed and difficult to ascertain, and clinical uncertainty is common, explaining the need for rapid diagnosis and a management plan. The primary aim of our study is to assess a diagnostic strategy using multiorgan point of care ultrasonography (USG) to differentiate patients presenting with acute dyspnea to ED into different diagnostic categories for timely management in a resource-limited setting...

PURPOSE: We aimed to present three new ultrasound signs-gallbladder scalloping, mammillated caudate lobe, and inferior vena cava scalloping-and determine their accuracy in diagnosing liver cirrhosis. MATERIALS AND METHODS: A total of 201 consecutive patients with a history of chronic liver disease who had undergone ultrasound imaging and liver biopsy were identified. A senior ultrasound radiologist blindly reviewed the ultrasound examinations. Specificity, sensitivity, positive predictive value, and negative predictive value of diagnosing cirrhosis were calculated for all evaluated ultrasound signs and selected combinations of signs, using the liver biopsy results as the reference standard...

PURPOSE: Central catheter placement is one of the most commonly performed procedures by pediatric surgeons. Here, we present a case series of patients where central access was obtained at our institution with the utilization of a novel ultrasound-guided technique. This series represents the first of its kind where the native, parent vessels were inaccessible, resulting in a challenging situation for providers. METHODS: A retrospective chart review was performed in pediatric patients (0-17 years) at a tertiary care institution between July 2012 and November 2017 on all central line procedures where ultrasound was utilized to cannulate the brachiocephalic or superior vena cava in face of proximal occlusion...

INTRODUCTION: Spontaneous migration of synthetic grafts had been described after abdominal vascular procedures into the duodenum and small bowel. In the setting of liver transplantation, synthetic grafts are commonly used for overcoming shortened or poor-quality vasculatures. We describe a case of spontaneous migration of thrombosed synthetic vascular graft after living-donor liver transplantation (LDLT). PRESENTATION: A 59 years male patient with end stage liver disease underwent LDLT utilizing a right hemi-liver graft...

PURPOSE: The sonographic evaluation of inferior vena cava diameters and its collapsibility-that is also defined as the caval index-has become a popular way to easily obtain a noninvasive estimate of central venous pressure. This is generally considered an easy sonographic task to perform, and according to the American College of Emergency Physicians (ACEP) Guidelines 25 repetitions of this procedure should be sufficient to reach proficiency. However, little is known about the learning process for this sonographic technique...

Merkel cell carcinoma is a primary neuroendocrine tumour of the skin arising from the dermis and extending into the subcutis, occurring commonly in sun-exposed areas of the head and neck of the elderly. Clinically, non-specific erythematous or violaceous firm nodules or small plaques which may be surrounded by small adjacent satellite tumours are seen. Diagnosis of Merkel cell carcinoma is difficult by light microscopy alone and need of ancillary techniques like electron microscopy and immunohistochemistry may be necessary...

BACKGROUND: Occlusion of the inferior vena cava (IVC) often causes venous claudication, leg swelling, or skin changes. We hypothesized that the outcome of nitinol stents for endovascular reconstruction of the IVC is similar to the outcome reported for steel alloy stents. METHODS: From the prospective Bern Venous Stent Registry, we investigated technical success, patency rates, and clinical outcome in consecutive patients with endovascular IVC reconstruction. During routine follow-up visits, stent patency was assessed by duplex ultrasound...

INTRODUCTION: Ultrasound assessment of the inferior vena cava (IVC) has gained favour in aiding fluid management decisions for controlled, mechanically ventilated patients as well as in non-mechanically ventilated, spontaneously breathing patients. Its utility in spontaneously breathing patients during positive pressure non-invasive ventilation has not yet been determined. The use of the axillary vein, as an alternative option to the IVC due to its ease of accessibility and independence from intra-abdominal pressure, has also not been evaluated...

RATIONALE: Although an inferior vena cave (IVC) filter is placed to prevent fatal pulmonary embolism (PE), several complications associated with an IVC filter have been reported. We describe a case with symptomatic PE, of which the origin was an occlusive IVC thrombus that developed from the placement of an IVC filer after a laparoscopy-assisted total gastrectomy (LATG). PATIENT CONCERNS: A 71-year-old man underwent LATG under general anesthesia alone. He had an IVC filter implanted 13 years ago...

REVIEW
Espeed Khoshbin, Stephan Schueler
Explantation of a left ventricular assist device (LVAD) may be challenging even in the most experienced hands. We aim to describe the technique for explantation of an LVAD together with the heart as applicable to all contemporary implantable mechanical assist devices. In order to ensure safe explantation, particular care must be taken at three distinct stages: at the time of LVAD implantation, at pre-transplant assessment and at the time of heart transplantation. The preparation for a safe explantation at LVAD implantation includes positioning the driveline and the outflow graft away from the back of the sternum to ensure protection from injury during re-entry into the chest...
