We report a case in which strict anticoagulant therapy management was useful for a recurrent in-stent thrombosis after carotid artery stenting (CAS). An 84-year-old man presented with cognitive decline that progressed rapidly over two months. Head magnetic resonance imaging showed an acute-stage infarct occurring frequently in the right cerebral hemisphere, and he underwent hospitalization and treatment. On neck magnetic resonance angiography (MRA), severe stenosis was found at the origin of the right internal carotid artery...

Portal vein thrombosis remains a challenging issue in liver transplantation. When thrombectomy is not feasible due to diffuse portosplenomesenteric thrombosis, other modalities are adapted such as the use of a jump graft or portal tributaries or even multivisceral transplantation. For patients with diffuse thrombosis of the splanchnic venous system, a large pericholedochal varix can be a useful vessel for providing splanchnic blood flow to the graft and for relieving portal hypertension. We report our experience of successfully treating a patient with diffuse portosplenomesenteric thrombosis using a pericholedochal varix for portal flow reconstruction during deceased donor liver transplantation and eventually preventing unnecessary multivisceral transplantation...

Large-for-size syndrome (LFSS) is controversial in pediatric living donor liver transplantation patients and is associated with a poor graft outcome. Similar situations in deceased donor liver transplantation (DDLT) in adults have not been reported frequently, and there are no official guidelines worldwide. Deceased donation is extremely limited in Japan, and when a larger liver is allocated for a very sick small recipient in Japan, transplantation with a plan to address LFSS might be necessary. The patient is a 58-year-old female patient who had acute liver failure with coma...

INTRODUCTION: We quantified intraneural blood flow (INBF) in 18 patients with end-stage kidney disease (ESKD) and examined its relationship with nerve size, neuropathy severity and nerve excitability parameters. METHODS: Sonographic measurements of the median nerve were performed at the same site before and after haemodialysis. INBF was quantified by analysing power Doppler sonograms to obtain the vessel score (VSc) and maximum perfusion intensity(MPI). Corresponding median motor nerve excitability studies were performed...

BACKGROUND/AIMS: Intraoperative cholangiogram (IOC) is commonly used to detect retained bile duct stones. This often leads to another invasive procedure such as endoscopic retrograde cholangiopancreatography (ERCP). However, due to the variation in methods and results of IOC, it is unclear if clinical factors will aid in identifying true choledocholithiasis. METHODS: All cholecystectomies in a 3 year period were examined retrospectively for positive IOC. Sonographic bile duct dilation and transaminase levels at admission including trends during the course of hospitalization and prior to ERCP were evaluated...

OBJECTIVES: Preoperative localization of parathyroid adenomas in patients with primary hyperparathyroidism facilitates targeted surgery. We assessed the sensitivity of 3-dimensional (3D) sonography for preoperative localization of abnormal parathyroid glands. METHODS: We conducted a retrospective review of patients who underwent parathyroidectomy for primary hyperparathyroidism at a single site at our institution. We compared preoperative 2-dimensional (2D) sonography, 3D sonography, and sestamibi scans with final gland localization at surgery...

Purpose: The purpose of this study was to evaluate the ultrasonographic findings associated with posterior interosseous nerve (PIN) syndrome. Methods: Approval from the Institutional Review Board was obtained. A retrospective review of 908 sonograms of the upper extremity from January 2001 to October 2010 revealed 10 sonograms suspicious for a PIN abnormality (7 male and 3 female patients; mean age of 51.8±13.1 years; age range, 32 to 79 years). The ultrasonographic findings of PIN syndrome, including changes in the PIN and adjacent secondary changes, were evaluated...

OBJECTIVE The risk of venous thromboembolism (VTE) from deep venous thrombosis (DVT) is significant in neurosurgical patients. VTE is considered a leading cause of preventable hospital deaths and preventing DVT is a closely monitored quality metric, often tied to accreditation, hospital ratings, and reimbursement. Adult protocols include prophylaxis with anticoagulant medications. Children's hospitals may adopt adult protocols, although the incidence of DVT and the risk or efficacy of treatment is not well defined...

OBJECTIVES: The 2012 Eunice Kennedy Shriver National Institute of Child Health fetal imaging consensus suggested that fetal anatomy ultrasound in obese pregnancies be performed at 20 to 22 weeks, with follow-up in 2 to 4 weeks if anatomy is incomplete. It was postulated that imaging in early gestation may improve visualization, although no prospective trials had been done to date. METHODS: We performed a prospective longitudinal blinded trial comparing an early gestation ultrasound (13 + 0 to 15 + 6 weeks) with the traditional second-trimester ultrasound for completion of the fetal anatomy survey in obese patients...

PURPOSE OF REVIEW: Traditionally, ovarian stimulation for IVF/intracytoplasmic sperm injection is performed by healthcare professionals, requiring the patient to make frequent visits to these centres. We describe the rationale, research findings and early clinical experience with home-based sonography for IVF patients. RECENT FINDINGS: Published experience indicates that selected patients are able to procure video sequences themselves; they value the empowerment, discretion and decreased stress involved in these visits; partner involvement increases as well...

Nghia Q Nguyen, Richard Prager
We previously developed unified pixel-based beamforming to generate high-resolution sonograms, based on field pattern analysis. In this framework, we found the transmit wave-shape away from the focus could be characterized by two spherical pulses. These correspond to the maximal and minimal distances from the imaging point to the active aperture. The beamformer uses this model to select the highest-energy signals from backscattered data. A spatiotemporal interpolation formula is used to provide a smooth transition in regions near the focal depth where there is no dominant reflected pulse...

BACKGROUND AND OBJECTIVES: Glossopharyngeal nerve (GPN) blocks are usually performed by topical, intraoral, or peristyloid approaches, which carry significant complication risks due to the proximity of important neurovascular structures. This study presents a proof of concept for a new ultrasound (US)-guided technique, which would block the GPN distally, in the parapharyngeal space, away from the immediate vicinity of high-risk collateral structures. METHODS: Five cadaver heads were dissected, and the location of the GPN was explored bilaterally...

BACKGROUND: Using a too big or a too small size of an endotracheal tube in pediatric patients would result in tracheal injury or insufficient ventilation. Determining the appropriate endotracheal tube size is important because using an inappropriate size can cause complications. This study was performed to predict the appropriate endotracheal tube size by measuring the transverse diameter of the epiphysis of the distal radius under the assumption that the growth rates of cartilages in the entire body are close to each other...

Unilateral fibrous contracture of the sternocleidomastoid (SCM) muscle is the major pathophysiology in infants with congenital muscular torticollis (CMT). Physical examination is not always sufficient to detect minimal muscle fibrosis in involved SCM muscles.A prospective study for SCM muscle fibrosis in CMT infants by quantifying echotexture and muscle thickness during the course of treatment is highlighted in the study.Convenience samples of 21 female and 29 male infants with CMT, who were 1 to 12 months old, underwent physiotherapy for at least 3 months and were followed for 4...
