Color Doppler ultrasonography is a reliable diagnostic tool in the diagnosis of extracranial vertebral artery dissections
AbstractThe purpose of this study was to evaluate the role of color Doppler sonography (CDS) in the diagnosis of extracranial vertebral artery dissections (EVADs). One hundred and fifty consecutive patients (age range 21 –51 years, mean 44 years) with a clinical suspicion of vertebral artery dissection (VAD) were included in this study. All patients underwent CDS of vertebral arteries as the first-line imaging modality. Cervical T1-weighted fat-saturated axial MR images served as the gold standard. Of the 150 pa tients with a clinical suspicion of VAD, 27 patients were ultimately diagnosed with EVADs based ...

Association of left ventricular myocardial dysfunction with diabetic polyneuropathy
This study examined the relationship between the severity of DPN and echocardiographic parameters as well as clinical features.MethodsThe subjects were 166 patients (57  ± 14 years old) with diabetes who had a normal LV ejection fraction (≥ 55%). To assess LV longitudinal systolic function, global longitudinal strain (GLS) was calculated by two-dimensional STE as the average peak strain of 18 LV segments in three standard apical views. A nerve conduction study (NCS) was performed in each subject to assess the severity of neuropathy based on the NCS Baba Classification (Grade 0: no appare...

Cancer therapeutics-related cardiac dysfunction in a patient treated with abiraterone for castration-resistant prostate cancer
We present a case of an 86-year-old man with castration-resistant prostate cancer treated with abiraterone. He had received an androgen receptor antagonist (bicalutamide) and a gonadotropin-releasing hormone antagonist (degarelix) for 3  years. These agents were changed to enzalutamide due to elevation of plasma prostate-specific antigen level of 129 ng/mL. One year later, the oral androgen receptor inhibitor (enzalutamide) caused drug-induced lung injury and was changed to abiraterone. Transthoracic echocardiography (TTE) reveal ed normal left ventricular systolic function, and left ventricular ejection fraction...

Indirect doppler ultrasound abnormalities of significant portal vein stenosis after liver transplantation
ConclusionIn addition to PFV-related abnormalities, DUS occasionally shows “no demonstrable color flow” either at recipient PVs or anastomoses, and indirect Doppler abnormalities such as turbulence, HFPF at graft PVs, and abnormal waveforms at graft HAs in LT recipients with significant PVS. The combination of PFV-related abnormalities and indirect DUS abnormalities wo uld be helpful for diagnosis of PVS. (Source: Journal of Medical Ultrasonics)

Delayed hemopericardium due to non-penetrating chest trauma: a report of new case and literature review
We present the case of a 63-year-old man with delayed hemopericardium, 2  months after striking the anterior chest on a mailbox when he fell down three steps during a postal delivery. Our case and review of the previously reported cases suggest that some cases might show quite slow progression of blood accumulation.

Prenatal findings of serpentine-like syndrome with congenital intrathoracic stomach: differential diagnosis from congenital diaphragmatic hernia
We report the prenatal findings of serpentine-like syndrome in a fetus at 18 weeks of gestation. The stomach was entirely elevated into the thoracic area, but the liver retained its normal position. Our initial diagnosis was isolated left co ngenital diaphragmatic hernia (CDH). At 20 weeks of gestation, the pregnancy was terminated, and a male newborn weighing 338 g was vaginally delivered. The autopsy findings revealed an extremely short esophagus, and the stomach was located in the posterior mediastinum as a result of congenital eso phagus hiatal hernia.

Preoperative diagnosis of a giant cell tumor of soft tissue arising from the breast by ultrasound-guided core needle biopsy
AbstractGiant cell tumors of soft tissue (GCT-ST) arising in the breast are extremely rare. Herein, we report a case of a 45-year-old woman with a 5-cm mass in her left breast. Ultrasonography revealed a mainly well-circumscribed mass that contained a cystic lesion. Magnetic resonance imaging showed a fibrous capsule-covered mass that contained a high-intensity area, suggesting hemorrhaging. Ultrasound-guided core needle biopsy (CNB) revealed mononuclear histiocytic cells with a round shape or spindled appearance that was mixed with multinucleated giant cells. Immunohistochemical analysis revealed CD68-positive staining in...

Ultrasonographic findings in a patient with reactive arthritis induced by intravesical BCG therapy for bladder cancer
AbstractIntravesical bacillus Calmette –Guerin (BCG) therapy is an effective and safe immunotherapy for superficial bladder cancer. However, reactive arthritis (ReA) is reported as an adverse event in about 0.5–1% of patients receiving intravesical BCG therapy. ReA is known as a kind of spondyloarthritis, the main pathological findin g of which is enthesitis. Here we report a patient with ReA induced by intravesical BCG therapy for bladder cancer, in whom the diagnosis of ReA was supported by ultrasonographic findings of enthesitis and synovitis. A 69-year-old male was diagnosed with carcinoma in situ of the bl...

Three-step procedure for safe internal jugular vein catheterization under ultrasound guidance
AbstractReal-time ultrasound guidance for central venous catheterization has become a standard technique. This technique has been reported to yield high success rates and fewer complications compared with landmark techniques. However, it can be risky when the practitioner does not possess proper knowledge and skills. Lose sight of the needle tip can lead to severe complications such as arterial puncture or pneumothorax. Also, posterior wall penetration of the target vessels must be avoided. Misplacement of the catheter to other vessels can sometimes occur, and may only be discovered after the catheterization procedure. To ...

The utility of superb microvascular imaging for the detection of deep vein thrombosis
AbstractSuperb microvascular imaging (SMI) reduces motion artifacts significantly and allows visualization of low-velocity blood flow in vessels; thus, thrombi are clearly demonstrated compared to conventional B-mode and color Doppler imaging. Ultrasonographic images of the lower extremities of a 69-year-old woman with acute ischemic stroke complicated with deep vein thrombosis (DVT) are presented. Because SMI allows visualization of low-velocity blood flow, echo contrast between the thrombus and the surrounding flow makes it possible to clearly visualize the thrombus. SMI is a useful method to evaluate DVT, especially ear...

Flexor pollicis longus tendon rupture by sandwiched underlying volar locking plate and distal radius
AbstractFlexor pollicis longus (FPL) tendon rupture is a major complication of volar locking plate fixation for distal radius fractures. The tendon rupture is usually caused by friction between the distal edge of the plate and the FPL tendon, and has been well detected recently with ultrasonography. Rarely, the volar locking plate itself entraps the FPL tendon, leading to its rupture. A 63-year-old man was consistently unable to flex his right thumb after previous surgery for a distal radius fracture at another hospital. Ultrasonography demonstrated loss of tendon gliding and unusual patterns of the FPL tendon. The tendon ...

Vascular ultrasound in pediatrics: utility and application of location and measurement of jugular and femoral vessels
ConclusionsIn pediatric patients, major vessels can be located and their depth and diameter measured by vascular ultrasound. In younger patients, jugular and femoral vessels had similar depth values; in older ones, they had similar diameters. Ultrasound measurements in pediatric patients could facilitate the choice of the vessel to be cannulated, the catheter diameter, and the length of the needle to be used. Vascular canalization of IJV may be recommended as the first choice because of its low depth and large diameter. (Source: Journal of Medical Ultrasonics)
