Quantification of the cerebrospinal fluid (CSF) system may be useful for distinguishing relative treatments in the presence of choroid plexus papillomas (CPPs). To study the CSF system, mathematical models and simulations detailing the cerebral blood flow and CSF filtration were constructed to represent a normal brain, a brain with CPP located in the left lateral ventricle, and a brain with CPP...
A case of transcatheter occlusion of a Blalock-Taussig shunt with a detachable silicone filled balloon is described. This 11 year old boy had previously had a repair of tetralogy of Fallot together with ligation of a large Blalock-Taussig shunt. Though there was a good surgical result, the shunt proved to be incompletely closed leaving a significant left to right shunt. As an alternative to a f...
The shunt-LDO regulator is a new regulator concept which combines a shunt and a Low Drop-Out (LDO) regulator. Designed as an improved shunt regulator to match the needs of serially powered detector systems, it can also be used as a pure LDO regulator for general application in powering schemes requiring linear regulation. The flexibility of the design makes the shunt-LDO regulator a good candid...
BACKGROUND Ventriculoperitoneal (VP) shunt insertion remains the mainstay of treatment for hydrocephalus despite a high rate of complications. The predictors of shunt malfunction have been studied mostly in pediatric patients. In this study, we report our 11-year experience with VP shunts in adult patients with hydrocephalus. We also assess the various factors affecting shunt survival in a deve...
hepatoportal sclerosis or idiopathic portal hypertension has a worldwide distribution with prevalence in developing and temperate countries. of 64 patients with this disease seen during a twelve year period, 36 underwent splenectomy or a shunt procedure. the indications for surgical intervention were severe hypersplenism and persistent left upper abdominal pain andlorhistory of frequent episode...
A 12-year-old who had a ven triculoa trial shunt for hydrocephalus due to congenital aqueduct stenosis and later developed shunt nephritis is reported. His renal function detoriated progressively within eight months while he was lost to follow-up. After removing the shunt. and with appropriate aggressive treatment renal function improved and complement levels returned to normal. Early removal o...
BACKGROUND Aspirin (ASA) often is used to prevent thrombosis in infants with congenital heart disease after placement of a systemic-to-pulmonary artery shunt, but its effect on outcomes is unknown. METHODS AND RESULTS The present multicenter study prospectively collected data on 1-year postoperative rates of death, shunt thrombosis, or hospitalization age <4 months for bidirectional Glenn/hem...
Ventricular shunt tap as a predictor of proximal shunt malfunction in children: a prospective study.
OBJECT The clinical diagnosis of cerebrospinal fluid (CSF) shunt malfunction can be challenging. In this prospective study, the authors evaluated a common method of interrogating shunts: the shunt tap; specifically, its ability to predict proximal malfunction. METHODS The authors performed standardized shunt taps in a consecutive series of cases involving children with suspected or proven shu...
