A 22 years-old-man was admitted to emergency after trauma. He suffered multiple deep cuts on his left leg. A lesion of the ischiatic nerve was suspected, and an ultrasound (US) evaluation was requested to confirm it. The study was conducted in the emergency room using a linear ultrasound transducer of 6-15 MHz and demonstrated the completely truncation of the ischiatic nerve (neurotmesis - Sunderland Grade V) with the proximal end retracted up to about 3cm from the edge of the wound. It was a very useful information for the neurosurgeon who after performed an end-to-end neurorrhaphy with suturation of perineurium...

We present the case of a 17-year-old girl with Ebstein anomaly and repeated episodes of reentrant tachycardia due to a right posterior accessory pathway. Catheter ablation was performed using intracardiac echocardiography. A ViewFlex Xtra probe was inserted and showed an anormal tricuspid valve with elongated anterior leaflet and low insertion of the septal leaflet towards the apex. The anatomical annulus was identified by the course of the right coronary artery. RF application on the posterior annulus stopped the reentrant arrhythmia...

Tuberculosis-associated pericardial disorders are an excessively rare manifestation of extrapulmonary tuberculosis. The patients may present with constrictive pericarditis or pericardial fluid accumulation leading to cardiac tamponade. This paper reports a case of tuberculosis-associated pericardial effusion with dense fibrinous material not causing tamponade in a foreigner presenting with nonspecific symptoms. It also provides a discussion about the diagnostic and therapeutic methods as well as interesting echocardiographic images of the patient...

Inflammatory bowel diseases have an important impact upon the economic and social status due to their increasing incidence and prevalence, often affecting young people. At the moment, the therapeutic goal goes beyond the improvement of symptoms and laboratory parameters, being represented by endoscopic mucosal healing, changing the disease's natural history. Even though endoscopy is the gold standard for the assessment of mucosal healing, it is an invasive maneuver and it lacks good repeatability. These patients require frequent evaluation; therefore, interest for noninvasive techniques has risen...

Open spina bifida, also known as spina bifida aperta is a neural tube defect involving the lack of closure of vertebral arches and associated meninges and/or spinal cord abnormalities.Ultrasound examination is the gold standard for the diagnosis of spina bifida aperta. It represents the main imaging tool used to ascertain this diagnosis early in gestation. Three-dimensional ultrasound is necessary to detect the level and the size of the defect. Magnetic resonance imaging (MRI) represents a more sensitive tool, giving specific information of the defect and associated anomalies, playing an important role in ruling out differential diagnosis...

AIMS: Foramen ovale (FO) valve with a shape or motion abnormality is frequently detected during routine obstetric ultrasonic examinations. However, the hemodynamics mechanism of this entity remains unclear. The purpose of the study is to determine the relevance of interatrial communication restriction and resultant morphological modifications. MATERIALS AND METHODS: We reviewed the echocardiographic records of fetuses with isolated abnormal FO valve evaluated between January of 2010 and december of 2016...

AIMS: Left ventricular global longitudinal strain (GLS) was shown to predict outcomes after valve replacement in patients with aortic stenosis (AS). In the current study, we aimed to test the combined use of GLS and a marker of fibrosis - Galectin-3 - for predicting major cardiovascular adverse events (MACEs) in patients with severe AS. MATERIALS AND METHODS: We conducted a prospective study on 42 patients with severe AS and 42 volunteers. Patient evaluation included biochemistry tests, electrocardiogram, 24-hour Holter monitoring, the 6-minute walk test, and echocardiography...

AIM: Regional anesthesia with ultrasound-guidance is an excellent option for pain control if nerves are adequately visualized. Gender, body mass index (BMI), history of diabetes, neck and forearm circumference may affect echotexture and visualization. This study evaluates patient characteristics for their ability to predict the echogenicity or visibility of upper extremity peripheral nerves. MATERIAL AND METHODS: This is a prospective observational study. A convenience sample of adult emergency department patients were enrolled...

AIM: To investigate strain (SE) and shear wave elastography (SWE) characteristics of the long head of the biceps tendon (LHBT) tendinosis in comparison with magnetic resonance imaging (MRI) findings. MATERIAL AND METHODS: Twenty patients with a MRI diagnosis of tendinosis and twenty healthy subjects with normal LHBT in MRI were prospectively examined by SE and SWE. SE color mapping was divided into four types in accordance with elasticity designs: type I predominantly blue (hardest tissue), type II predominantly blue-green (hard tissue), type III predominantly green (intermediate tissue), type IV predominantly green-yellow-red (soft tissue)...

AIM: To evaluate the presence and distribution of calcium pyrophosphate (CPP) deposits in joints commonly affected by CPP deposition (CPPD) disease (acromio-clavicular, gleno-humeral, wrists, hips, knees, ankles, and symphysis pubis joints) using ultrasound (US). MATERIAL AND METHODS: Thirty consecutive patients fulfilling McCarty diagnostic criteria for CPPD were consecutively enrolled in the study. The data registered using the US included the affected joints, the calcification site, and the pattern of calcification (thin hyperechoic bands, parallel to the surface of the hyaline cartilage, hyperechoic spots, and hyperechoic nodular or oval deposits)...

AIM: The aim of this study was to identify easy and relatively effective ultrasound criteria for metastatic mediastinal lymph node prediction. MATERIALS AND METHODS: A retrospective chart review of patients who underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) from March 2014 to September 2016 was performed. We used the following EBUS sonographic features for metastatic lymph node prediction: 1) length of the short axis, 2) shape, 3) margin, 4) echogenicity, 5) central hilar structure, and 6) coagulation necrosis sign...
