1. Caliber-persistent labial artery: report of 3 cases
Abstract The caliber-persistent labial artery is a vascular anomaly in which a primary arterial branch penetrates into the submucosal tissue without reduction in diameter. Most lesions are benign and do not require treatment, except for complications and/or on patient demands. In this way, noninvasive diagnostic tools are preferred such as high-resolution an

2. Análise do grau de recanalização da trombose venosa profunda: estudo comparativo de pacientes tratados com varfarina versus rivaroxabana
Resumo Contexto A trombose venosa profunda (TVP) afeta anualmente cerca de dez milhões de pessoas no mundo e tem como principais complicações a embolia pulmonar e a síndrome pós-trombótica. O tratamento padrão é a anticoagulação, que pode ser realizada com heparinas, antagonistas da vitamina K, fondaparinux ou, mais recentemente, com anticoagulant

3. Ultrasonography and portography in the diagnosis of shunt portoazigos in a dog - case report
RESUMO Shunt portossistêmico (SPS) é uma comunicação vascular anômala entre o sistema venoso portal e a circulação sistêmica. Esses desvios comunicam a VP ou alguma de suas tributárias à veia cava ou, menos comumente, à veia ázigos (VA). O objetivo do presente estudo foi descrever o diagnóstico, por meio de ultrassonografia e portografia, de um

4. A pancreatic hemorrhagic pseudocyst with pseudoaneurysm and the role of doppler ultrasonography: a case report
SUMMARY Hemorrhagic pseudocysts with pseudoaneurysms are a rare and fatal complication of chronic pancreatitis due to the erosion of pancreatic to peripancreatic arteries. The timing of the rupture cannot be accurately predicted, but prompt diagnosis and management are essential to prevent further bleeding. We describe the case of a 68-year-old man who prese

5. Cervical Cannulation for Surgical Repair of Congenital Cardiac Defects in Infants and Small Children
Abstract INTRODUCTION: The biggest challenge faced in minimally invasive pediatric cardiac surgery is cannulation for cardiopulmonary bypass. Our technique and experience of cervical cannulation in infants and small children for repair of congenital cardiac defects is reported in this study. METHODS: From January 2013 to June 2015, 37 children (22 males) w

6. High frequency ultrasound with color Doppler in dermatology
Abstract: Ultrasonography is a method of imaging that classically is used in dermatology to study changes in the hypoderma, as nodules and infectious and inflammatory processes. The introduction of high frequency and resolution equipments enabled the observation of superficial structures, allowing differentiation between skin layers and providing details for

7. Blood flow velocity in monocular retinoblastoma assessed by color doppler
OBJECTIVE: To analyze the flow of retrobulbar vessels in retinoblastoma by color Doppler imaging. METHODS: A prospective study of monocular retinoblastoma treated by enucleation between 2010 and 2014. The examination comprised fundoscopy, magnetic resonance imaging, ultrasonography and color Doppler imaging. The peak blood velocities in the central retinal

8. Is quantitative diffusion-weighted MRI a valuable technique for the detection of changes in kidneys after extracorporeal shock wave lithotripsy?
Objective The aim of this study was to evaluate the capability and the reliability of diffusion-weighted imaging (DWI) in the changes of kidneys occurring after extracorporeal shock wave lithotripsy (ESWL) treatment for renal stones. Materials and Methods A total of 32 patients who underwent ESWL treatment for renal stone disease between June and December 2

9. Can Doppler or contrast-enhanced ultrasound analysis add diagnostically important information about the nature of breast lesions?
OBJECTIVES: Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after micr

10. Ultrassonografia e CA-125 como preditores de malignidade em mulheres com tumores anexiais / Ultrasonography and CA-125 as predictors of malignancy in women with adnexal tumors
Introduction: Ovarian cancer is the deadliest gynecologic neoplasm and it is the fifth leading cause of cancer-related deaths in women. The survival rate is low, not exceeding 40% after 5 years and is directly related to tumor stage at the time of diagnosis. To date there is still no screening method that is effective at reducing mortality from this neoplasm

11. The role of the resistive index in Hashimoto's thyroiditis: a Sonographic pilot study in children
OBJECTIVE: The role of Doppler ultrasonography in the diagnosis of diffuse thyroid diseases is not well established. In particular, Doppler ultrasonography findings in children with Hashimoto's thyroiditis are very limited. We examined gray-scale and Doppler ultrasound findings in Hashimoto's thyroiditis in children in an attempt to understand the feasibilit

12. Is the measurement of inferior thyroid artery blood flow velocity by color-flow Doppler ultrasonography useful for differential diagnosis between gestational transient thyrotoxicosis and Graves' disease? A prospective study
OBJECTIVE: To determine the role of peak systolic velocity, end-diastolic velocity and resistance indices of both the right and left inferior thyroid arteries measured by color-flow Doppler ultrasonography for a differential diagnosis between gestational transient thyrotoxicosis and Graves' disease during pregnancy. METHODS: The right and left inferior thyro
