Several thousand life-saving liver transplants are performed each year. One of the most common causes of early transplant failure is arterial stenosis of the anastomotic junction. Early detection of transplant arterial stenosis can help prevent transplant failure and the need to re-transplant. Doppler ultrasound is the most common screening method, but it suffers from poor specificity. Positive screening cases proceed to angiography which is an invasive and expensive procedure. A more accurate test could decrease the number of normal patients who would have to undergo this invasive diagnostic procedure...

There are so far only a few reported cases of acute fulminant hepatic failure resulting from acute cardiomyopathy. This is a rare occurrence, especially in patients that do not exhibit any signs and symptoms of acute cardiac decompensation. We report a case of fulminant liver failure with nondiagnostic work up for the common causes of liver failure. This patient had concurrent history of congestive heart failure, but did not have acute decompensation. Right upper quadrant sonogram revealed hepatomegaly of 15 cm, trace amount of perihepatic ascites, pericholecystic fluid, and also thickened edematous gallbladder wall with no stones, no common bile duct stones, and no portal vein thrombosis...

OBJECTIVES: Objective measures are needed to guide the novice's pathway to expertise. Within and outside medicine, eye tracking has been used for both training and assessment. We designed this study to test the hypothesis that eye tracking may differentiate novices from experts in static image interpretation for ultrasound (US)-guided regional anesthesia. METHODS: We recruited novice anesthesiology residents and regional anesthesiology experts. Participants wore eye-tracking glasses, were shown 5 sonograms of US-guided regional anesthesia, and were asked a series of anatomy-based questions related to each image while their eye movements were recorded...

Most sacrococcygeal teratomas present between the 22nd and the 34th week of gestation. The diagnosis of sacrococcygeal teratoma on routine antenatal sonograms is associated with a greater than expected incidence of prenatal and perinatal complications. We report a premature baby with intrauterine spontaneous rupture of giant sacrococcygeal teratoma which was managed successfully.

Timothy P Canavan
Pregnancy is frequently a women's first contact with the health care system and often her first pelvic ultrasound examination. This first sonogram can reveal previously unknown adnexal pathology. Approximately 4% of pregnant women will have an adnexal mass detected by sonography and 1% to 2% of these masses will persist. It is estimated that up to 7% of these persistent masses will be malignant. Sonography plays an important role in differentiating benign from malignant adnexal masses and physiological from pathologic masses and should be used judiciously to complement evaluation and help guide treatment...

Obstetric protocols dictate that the fetal cerebellum should always be assessed during sonograms during pregnancy. For various reasons, including technical limitations or inconclusive sonographic findings, suspicion of cerebellar abnormalities is one of the most common indications for prenatal magnetic resonance imaging (MRI). Although sonography is the imaging technique of choice to assess the cerebellum, MRI shows the anatomy of the posterior fossa and abnormalities in the development of the fetal cerebellum in greater detail and thus enables a more accurate prenatal diagnosis...

PURPOSE: The one-step approach for screening of GDM will increase the incidence 2- to 3-fold. These larger cohorts may need to target high-morbidity subsets to be cost-effective. We asked whether ultrasound could stratify the GDM patients with the highest risk for a large for gestational age (LGA) infant. MATERIALS AND METHODS: A retrospective analysis was performed on 413 GDM patients diagnosed using the one-step approach. Ultrasound data from 28 weeks 0 day to 34 weeks 6 days was studied...

Endocrine-disrupting chemical (EDC) has been thought to play a role in non-alcoholic fatty liver disease (NAFLD). However, the toxic effects of Nonylphenol (NP), an EDC, on non-alcoholic fatty liver disease have never been elaborated. This study aimed to investigate whether exposure to NP could induce NAFDL, a promoting effect of high-sucrose-high-fat diet (HSHFD) on the adverse effects caused by NP was evaluated. Fourth eight male rats were assigned to four groups and each group was treated with a specific testing sample: normal-diet (ND) control group (C-ND); normal diet plus NP (180mg/kg/day) group (NP-ND); high-sucrose-high-fat-diet control group (C-HSHFD); HSHFD plus NP (180mg/kg/day) group (NP-HSHFD)...

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...
