An investigation of the standardization of fetal cavum septi pellucidi measurements using three-dimensional volumes of the fetal head.

J Clin Ultrasound 2019 Apr 7. Epub 2019 Apr 7.

Department of Ultrasound, Shengjing Hospital of China Medical University, Shenyang, China.

Purpose: The purpose of this study was to measure the maximal width, middle width, and length of the cavum septi pellucidi (CSP) in normal fetuses, and compare these measurements obtained in the transthalamic (TT) plane with those obtained in the transventricular (TV) plane.

Method: A prospective study was conducted of normal singleton fetuses, ranging from 18 to 36 weeks in gestational age. In each case, a three-dimensional volume of the fetal head was obtained in the TT plane for further offline measurements, then the maximal width, middle width, and length of the CSP in both the TT and TV planes were measured.

J Clin Ultrasound 2019 Feb 14. Epub 2019 Feb 14.

Department of Laboratory Medicine, Saitama Medical Center, Jichi Medical University, Saitama, Japan.

Leiomyosarcoma of the inferior vena cava is a rare malignant tumor originating from smooth muscle cells of the vascular media. Its preoperative diagnosis by conventional noninvasive examinations such as abdominal ultrasonography, X-ray computed tomography, and magnetic resonance imaging, may be difficult because of their nonspecific findings. We present the case of a 72-year-old woman with leiomyosarcoma of the inferior vena cava diagnosed by intravascular ultrasonography. Read More

Department of Cardiology, Medipol University Camlica Hospital, Istanbul, Turkey.

Although late complications of percutaneous closure of atrial septal defect (ASD), including cardiac erosion and thrombosis, are rare, they are the most lethal. Data are still lacking regarding the usefulness of new imagining modalities, such as three-dimensional echocardiography (3DE), for the detection of these complications. Here, we report the case of a 57-year-old woman in whom cardiac erosion was very well visualized by 3D transesophageal echocardiography (3D TEE) after percutaneous ASD closure. Read More

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. Read More

Usefulness of ultrasound fetal anthropometry in primary and secondary screening to identify small for gestational age: A meta-analysis.

Authors:
Eita Goto

J Clin Ultrasound 2019 May 11;47(4):212-218. Epub 2019 Jan 11.

Department of Medicine and Public Health, Nagoya Medical Science Research Institute, Nagoya, Japan.

Purpose: This study was performed to evaluate the usefulness of ultrasound fetal anthropometry in primary and secondary screening to identify small for gestational age (SGA).

Methods: Ten databases, for example, PubMed (MEDLINE), were searched to include all English-language studies published since 2015 that provided true-positive and false-positive and true-negative and false-negative results of SGA identification. A bivariate diagnostic meta-analysis was performed to summarize the sensitivity and specificity as well as positive and negative likelihood ratios (PLR and NLR, respectively) of ultrasound fetal anthropometry for identification of SGA.

Identification of a giant mediastinal teratoma by echocardiography: A case report.

J Clin Ultrasound 2019 Jan 11. Epub 2019 Jan 11.

Department of Echocardiography, The First Hospital of Jilin University, Changchun, Jilin, China.

The diagnosis of mediastinal space-occupying lesions largely relies on X-ray and computed tomography. However, thanks to technological progress, transthoracic echocardiography can clearly display the mediastinal structures surrounding the heart and great vessels, thereby improving the detection rate of mediastinal space-occupying lesions. Primary mediastinal teratoma is relatively rare, and removal of giant mediastinal teratoma by thoracoscopic surgery has rarely been reported. Read More

Left ventricular global longitudinal strain and mechanical dispersion predict response to multipoint pacing for cardiac resynchronization therapy.

J Clin Ultrasound 2019 Jan 11. Epub 2019 Jan 11.

Department of Echocardiography, Zhongshan Hospital, Fudan University, Shanghai, China.

Purpose: To evaluate the acute effect of multipoint pacing (MPP) and search for the better baseline predictors of response to MPP for guiding patient selection.

Methods: We enrolled 46 heart failure patients scheduled for implantation of MPP-enabled cardiac resynchronization therapy (CRT) devices. An acute pacing protocol including conventional CRT and MPP pacing configurations was performed after implantation. Read More

Ventricular septal rupture with right ventricular wall dissection after inferior ventricular infarction: A case report and literature review.

J Clin Ultrasound 2019 May 4;47(4):247-252. Epub 2019 Jan 4.

Department of Cardiovascular Ultrasound, The First Hospital of China Medical University, Shenyang, Liaoning, China.

Right ventricular (RV) wall dissection following ventricular septal rupture related to inferior myocardial infarction (MI) is an extremely rare complication with a high mortality rate. We report the case of a 61-year-old man who was admitted to our hospital because of syncope and intermittent chest pain with a precordial murmur. Transthoracic echocardiography showed a rupture at the basal infero-posterior septum and RV free-wall dissection forming an echolucent cavity that extended beyond the septum and subsequently re-entered into RV chamber.

Presence of fragmented QRS is associated with increased epicardial adipose tissue thickness in hypertensive patients.

J Clin Ultrasound 2019 Jan 4. Epub 2019 Jan 4.

Department of Cardiology, Hitit University Faculty of Medicine, Çorum, Turkey.

Background: Epicardial adipose tissue (EAT) is a cardiometabolic risk factor, and its possible relationship with hypertension has been reported previously. Fragmented QRS (fQRS) detected on electrocardiography (ECG) has been demonstrated to be a marker of myocardial fibrosis. In this study, we aimed to investigate the relationship between the thickness of EAT, and presence of fQRS in hypertensive patients. Read More

Cross-sectional area of the median nerve at the wrist: Comparison of sonographic, MRI, and cadaveric measurements.

J Clin Ultrasound 2019 Mar 29;47(3):122-127. Epub 2018 Dec 29.

Department of Orthopaedics & Traumatology, Prince of Wales Hospital, Shatin, NT, Hong Kong.

Background: This study compares median nerve cross-sectional area (CSA) measurements at the wrist obtained with ultrasound (US) and magnetic resonance imaging (MRI) using cadaveric measurements as the gold standard.

Methods: Median nerve CSA was measured using US and MRI in 9 cadaveric wrists obtained from 5 subjects at 5 locations: distal forearm, proximal to tunnel inlet, at tunnel inlet, at tunnel outlet, and distal to tunnel outlet and then on identical cadaveric transverse sections obtained with a bandsaw. All US, MRI, and cadaveric measurements were repeated to determine reliability. Read More
