BACKGROUND: Choroid plexus tumors are rare entities. Resection is the mainstay of treatment in grade I and grade II tumors and adjuvant treatment is usually reserved for the less frequent choroid plexus carcinoma (CPC). Outcome is not only related to their histological grade but also dependent on their size, location, and presence of often multifactorial disturbances of cerebrospinal fluid (CSF) circulation. METHODS: Retrospective analysis of 36 consecutive patients operated on a choroid plexus tumor at our institution in a mixed pediatric and adult population between 1991 and 2016...

BACKGROUND: Cardiac dysfunction is frequently observed in patients with cirrhosis. There remains a paucity of data from routine clinical practice regarding the role of echocardiography in the pre-assessment of transjugular intrahepatic portosystemic stent-shunt. AIM: Our study aimed to investigate if echocardiography parameters predict outcomes after transjugular intrahepatic portosystemic stent-shunt insertion in cirrhosis. METHODS: Patients who underwent echocardiography and transjugular intrahepatic portosystemic stent-shunt insertion at the liver unit (Birmingham, UK) between 1999 and 2016 were included...

OBJECTIVES: Repair of tetralogy of Fallot (ToF) can be challenging in the presence of an abnormal coronary artery (CA) in 5-12% of cases. The aim of this study was to report our experience with ToF repair without the systematic use of a right ventricle-to-pulmonary artery (RV-PA) conduit. METHODS: We conducted a monocentric retrospective study from 2000 to 2016, including 943 patients with ToF who underwent biventricular repair, of whom 8% (n = 76) presented with an abnormal CA...

The ductus venosus plays a critical role in circulatory adaptation to hypoxia in fetal growth restriction, but the mechanisms still remain controversial. Increased shunting of blood through the ductus venosus under hypoxic conditions has been shown in animal and human studies. The hemodynamic laws governing the accelerated flow in this vessel suggest that any dilatation at its isthmus, which increases the blood flow shunting to the heart, is associated with a low, absent or reversed a-wave, and a high pulsatility index...

A bicuspid aortic valve and/or coarctation of the aorta (COA) are often associated with dilatation of the ascending aorta and para-coarctation. Congenital heart diseases (CHD), such as truncus arteriosus, transposition of the great arteries (TGA), tetralogy of Fallot (TOF), hypoplastic left heart syndrome (HLHS), single ventricle with pulmonary stenosis/atresia and the Fontan procedure, are also associated with aortic root dilatation, aneurysm and rarely, dissection, which can be fatal and require aortic valve and root surgery...

BACKGROUND:  The timing of surgical repair of tetralogy of Fallot (TOF) is a key to alleviate complications and for long-term survival. Total correction was usually performed at the age of 6 months or older under the notion of decreasing the surgical risk. However, avoiding palliation with an aortopulmonary shunt and early correction of systemic hypoxia appear to be of more benefit than the inborn surgical risk in low body weight patients. Our objective was to assess early/midterm survival and operative complications and to analyze patients, surgical techniques, and morphological risk factors to determine their effects on outcomes...

IntroductionPulmonary atresia, ventricular septal defect, major aorto-pulmonary collateral arteries, and pulmonary arteries hypoplasia are rare and complex congenital defects that require early interventions to relieve cyanosis and enhance the growth of native pulmonary arteries. The treatment of these patients is still controversial. Surgical techniques require cardiopulmonary bypass which is poorly tolerated by small infants. Percutaneous techniques such as radiofrequency perforation can be challenging. The hybrid technique consists of perventricular stenting of the right ventricle outflow tract through medial sternotomy, to restore native pulmonary flow...

BACKGROUND: Negative-pressure hydrocephalus is a rare condition with the development of symptomatic hydrocephalus despite subnormal intracranial pressure (ICP). The etiology remains unclear. Some authors proposed that the differential pressure between the ventricular space and the subarachnoid space (SAS) over cerebral convexity leads to the development of ventriculomegaly, namely as the transmantle pressure theory. CASE DESCRIPTION: A 49-year-old with a left Sylvian fissure arachnoid cyst underwent several surgeries including cystoperitoneal shunts and fenestrations of the cyst...

PURPOSE OF REVIEW: Since it was first described in 1965, normal pressure hydrocephalus (NPH) has been a controversial subject. New studies have shed light on its epidemiology and pathogenesis and provided objective ways to measure outcome in patients with NPH. Neuroimaging has improved and allows better recognition of both NPH and the presence of overlapping diseases RECENT FINDINGS: Several recent epidemiologic studies confirm that NPH is a rare disease, but the presence of large ventricles is a common finding with aging...

Repair of Ebstein anomaly has evolved over the last decade, and timing of repair remains variable. There have been no studies of exercise or functional capacity in patients who have had tricuspid valve surgery for Ebstein anomaly in adulthood. We aimed to compare exercise capacity before and after tricuspid valve repair or replacement for Ebstein anomaly in adults at Mayo Clinic. We performed a retrospective chart review of all patients with Ebstein anomaly who underwent tricuspid valve surgery at Mayo Clinic between June 2007 and January 2015...

CSF flow disorders are frequently encountered in children. The advent of MR technology with the emergence of new pulse sequences allowed better understanding of CSF flow dynamics. In this pictorial review, we aim to conduct a comprehensive review of the MR protocol used to study CSF flow disorders and to discuss the utility of each pulse sequence in the adopted protocol. We will focus on the key anatomical structures that should be examined to differentiate hydrocephalus form ventricular dilatation ex-vacuo...

The rate of ventriculoperitoneal (VP) shunt infection is reported between 3% and 20%. Vancomycin-Resistant Enterococci (VRE) are increasingly prevalent nasocomial pathogens worldwide and they rarely cause infections to the central nervous system. Daptomycin is a cyclic lipopeptide effective antibiotic due to its rapid bactericidal effect. It is a life-saving treatment option for meningitis, bacteriemia, sepsis, endocarditis and urinary system infections caused by VRE. Here, we presented a 2.5-month-old male patient diagnosed with ventriculoperitoneal shunt infection caused by VRE faecium...
