OBJECT The object of this study was to mathematically model the prognosis of a newly inserted shunt in pediatric or adult patients with hydrocephalus. METHODS A structured search was performed of the English-language literature for case series reporting shunt failure, patient mortality, and shunt removal rates after shunt insertion. A metaanalytic model was constructed to pool data from multi...

Transepithelial secretion in Malpighian tubules of the yellow fever mosquito (Aedes aegypti) is mediated by active transport of Na(+) and K(+) through principal cells and passive Cl(-) transport through the shunt. Permeation through the shunt was assessed by measuring transepithelial halide diffusion potentials in isolated perfused Malpighian tubules, after first inhibiting active transport wit...

A case of E. coli meningitis in a patient with a ventriculoperitoneal shunt was encountered recently at our institution . A shunt-induced bowel perforation was demonstrated by injecting contrast material percutaneously into the proximal end of the shunt. Apparently, retrograde spread of normal bowel flora via the shunt was responsible for his unusual Gram-negative meningitis. Because of the dis...

We present a case of a 75-year-old man with nephrotic syndrome and renal insufficiency caused by immune complex-mediated secondary membranoproliferative glomerulonephritis. He developed hepatic encephalopathy. A congenital portosystemic shunt was identified, indicating a diagnosis of membranoproliferative glomerulonephritis with noncirrhotic portosystemic shunt. Proteinuria resolved after shunt...

A ventriculoperitoneal shunt is a surgical procedure that primarily treatsthe hydrocephalus which associated with many physical, psychological, and social problems thatcan affect on quality of life. Educational intervention has great effect in improving the qualityof life mothers their children shunt.

OBJECTIVE To evaluate the results of selective and nonselective emergency portosystemic shunts in patients with acute variceal hemorrhage. DESIGN Retrospective review. SETTING University medical center and Veterans Affairs medical center. PATIENTS Forty-two consecutive patients who underwent emergency portosystemic shunts from 1978 through 1994. All patients had chronic liver disease (29 ...

BACKGROUND In right ventricular failure (RVF), an interatrial shunt can relieve symptoms of severe pulmonary hypertension by reducing right ventricular preload and increasing systemic flow. Using a pig model to determine if a pulmonary artery-left atrium shunt (PA-LA) is better than a right atrial-left atrial shunt (RA-LA), we compared the hemodynamic effects and blood gases between the two shu...

A rare complication of ventriculoperitoneal shunting (VPS) is bowel perforation by the peritoneal catheter of the shunt tube. Rarer still is the peroral extrusion of such a perforated shunt. A two-month-old infant with history of neonatal meningitis, presented with a large head, bulging fontanelle, and hydrocephalus. A VPS was inserted. The child was doing well till the age of eight months, whe...

Complete occlusion of arteriovenous shunt is a feared complication of hemodialysis due to limited vessels suitable for reconstruction of arteriovenous shunt. For prolonged use of the arteriovenous shunt, there are many methods for restoring the function of the occluded arteriovenous shunts. So far the standard treatment for complete occlusion of arteriovenous shunt is surgery. Interventional pr...

The aim of this study is to report a case of gold shunt surgery for uncontrolled, low-tension glaucoma with good central vision, after having a previously failed trabeculectomy and tube shunt surgeries. The patient was receiving maximum medical glaucoma therapy of four different types with intraocular pressure of 17 mm Hg prior to gold shunt surgery. Five years later, intraocular pressure is we...
