Pulmonary embolism caused by postpartum ovarian vein thrombophlebitis after vaginal delivery: Case report and brief review of the literature.

Puerperal ovarian vein thrombophlebitis is a rare pathology. We present the case of a 23-year-old female who presented with fever and cough that occurred after vaginal delivery and persisted after several courses of antibiotics between the 2nd and 20th day postpartum. CT pulmonary angiography revealed right subsegmental pulmonary embolism. An abdominal ultrasonographic examination led to the diagnosis of ovarian vein thrombosis. She was treated with warfarin for 2 weeks with a good response. Our case high...

A giant atrial septal aneurysm causing tricuspid valvular obstruction.

Atrial septal aneurysm (ASA) is a rare congenital malformation consisting of redundant atrial septal tissue that bulges into either the right or the left atrium. Here, we report the case of a 45-year-old man with a giant ASA prolapsing into the tricuspid orifice and leading to tricuspid valvular obstruction. He was treated successfully by resection of the ASA and repair of the resulting atrial septal defect. Our case indicates the utility of transthoracic, contrast, and transesophageal echocardiography to c...

Shear-wave elastography of the liver in a healthy pediatric population.

The aim of this study was to determine the elastic modulus values of normal liver tissue in school-age children by shear wave elastography (SWE) and to study the factors that influence these stiffness measurements.

Assessment of right ventricular dysfunction in patients with mitral stenosis: A speckle tracking study.

Although it is affected at an early stage, there is a lack of studies investigating right ventricular (RV) function in patients with mitral stenosis (MS). We aimed to investigate the correlation between conventional echocardiographic variables and tricuspid annular plane systolic excursion (TAPSE), used as an indicator of RV dysfunction.

Clinical significance of early-diastolic tissue velocity imaging of lateral mitral annulus for prognosis of nonischemic left ventricular dysfunction.

We explored the potential of tissue velocity imaging (TVI) for prognosis of nonischemic left ventricular (LV) dysfunction (LVD).

Giant choledochal cyst and infantile polycystic kidneys as prenatal sonographic features of Caroli syndrome.

Caroli syndrome is a developmental disorder caused by complete or partial arrest of ductal plate remodeling, leading to dilated bile ducts along with fibrosis surrounding the portal tracts. It is most commonly associated with autosomal recessive polycystic kidney (ARPKD). We report a unique case of Caroli syndrome, diagnosed prenatally at 24 weeks of gestation in a 29-year-old Thai woman. Ultrasound findings revealed the association of a fetal giant choledochal cyst with ARPKD. Autopsy findings showed duc...

Association between grayscale sonographic and clinical findings in severe knee osteoarthritis.

To assess whether ultrasonographic (US) findings associate with clinical findings in severe knee osteoarthritis (OA). Association of US findings with side-of-knee pain and inter-reader agreement of knee US were also evaluated.

Discrepancy in Doppler waveforms between two umbilical arteries in fetuses with absent or reversed end-diastolic flow: A prospective observational study.

To asses the occurrence of discrepancies between the Doppler waveforms of the left and right umbilical arteries in their paravesical part in fetuses with absent or reversed end-diastolic flow in the free-floating umbilical cord.

ACR TI-RADS: An advance in the management of thyroid nodules or Pandora's box of surveillance?

Numerous sets of guidelines have been proposed regarding ultrasound of thyroid nodules. None has been universally accepted. American College of Radiology-Thyroid Imaging, Reporting and Data System (ACR-TIRADS) has been promoted as an improvement to existing guidelines such as the 2015 revised American Thyroid Association (ATA) guidelines. This commentary compares and contrasts these two guidelines. Adoption of TI-RADS is likely to result in large-scale, costly surveillance without clear benefit. Replacement...

Evaluation of saline versus gel as contact medium for ultrasonographic image quality.

Evaluate the time taken to visualize the internal jugular vein and carotid arteries, and subjective image quality assessed on a 0-100 visual analogic scale, on an ultrasound model using either traditional ultrasound gel or normal saline.

Three-dimensional speckle-tracking echocardiography for evaluating myocardial motion in patients with cardiorenal syndrome.

Because of better awareness and understanding of its pathophysiology, the cardiorenal syndrome (CRS) is more often diagnosed and better managed. The echocardiographic evaluation of CRS now benefits from three-dimensional speckle tracking echocardiography (3D-STE), which allows multidimensional and real-time evaluation of regional myocardial and overall cardiac function, and helps assessing the degree of myocardial damage. This article describes the application of 3D-STE in evaluating the myocardial motion i...

Primary cardiac lymphoma in both atria: A case report.

Primary cardiac lymphoma (PCL) is a very rare kind of primary heart tumor, belonging to non-Hodgkin's lymphoma whose major pathological type is diffuse large B-cell lymphoma. The common symptoms include heart failure, pericardial effusion, and malignant arrhythmias. Early diagnosis and treatment of PCL are of great importance due to its merely 7-month median survival period. Here, we report a 48-year-old male patient in whom both atria were involved and had to undergo palliative surgery because of severe cl...

Prenatal sonography of multicentric infantile myofibromatosis: Case report and review of the literature.

Scant literature exists on prenatally diagnosed infantile myofibromatosis (IM). We report a case of multicentric IM, which was first recognized as a soft-tissue paraspinal mass on prenatal sonography and subsequently characterized by MRI with pathological confirmation.

Doppler ultrasonographic evaluation of celiac and mesenteric arteries in subjects with sickle cell disease.

Vasculopathy, as occurring in sickle cell disease (SCD), can affect celiac and mesenteric arteries and result in stenosis, with elevated peak systolic velocity (PSV) on Doppler ultrasonography. In six subjects with confirmed SCD in steady state, routine Doppler ultrasonographic examination discovered features of celiac artery (CA) or superior mesenteric artery (SMA) stenosis with CA PSV >200 cm/s (median = 222.8 cm/s; range = 201.5-427.1 cm/s) and/or SMA PSV >275 cm/s (median 183.2 cm/s; range = 87....

Acute cardiac effects of high dose steroid treatment: A speckle tracking echocardiography study.

High-dose steroid therapy (HDST) has frequent side-effects that appear at its cessation and depend on its dose. However, there is a lack of studies about the acute effects of HDST on cardiac function in adult patients.

Middle cerebral artery peak systolic velocity in perinatal cytomegalovirus infection.

A middle cerebral artery peak systolic velocity value (MCA-PSV) persistently greater than 1.5 times the median of the normal population is utilized to detect moderate and severe anemia in fetuses at risk. Cytomegalovirus (CMV) is the most common perinatal infection and can cause fetal anemia. We present four cases with CMV perinatal infection. Although their MCA-PSV values were the highest recorded in normal as well as in anemic fetuses, only two of them developed moderate or severe anemia. These findings s...

The utility of superb-microvascular imaging for evaluating the full length of carotid artery stents.

Transoral carotid ultrasonography (TOCU) is a powerful tool for evaluating internal carotid artery (ICA) lesions located from the carotid bifurcation up to the level of the second cervical vertebra. Superb-microvascular imaging (SMI) is a new Doppler imaging technique whose algorithm analyze tissue movements to minimize motion artifacts by eliminating clutter signals. SMI significantly reduces motion artifacts and allows visualization of low-velocity blood flow even in minute vessels. TOCU with SMI produces...

Aortic sinus aneurysm rupture into the right atrium in a 29-year-old patient.

A 29-year-old man presented with chest tightness and shortness of breath. Physical examination showed jugular venous distention. Echocardiography showed a large saccular anechoic structure in the right atrium, swinging with the cardiac cycle. The operator initially mistook the lesion for a right atrial cystic tumor; however, color Doppler imaging showed abundant, high-velocity blood flow signals, leading to the diagnosis of giant aortic sinus rupture into the right atrium. Aortic sinus aneurysm is a rare an...
