BACKGROUND Shunt vessels were imaged and shunt flow was analysed by cross sectional and Doppler echocardiography in 12 patients who had had 14 shunt procedures (nine left Blalock-Taussig shunts, three right Blalock-Taussig shunts, one modified Waterston shunt, and one central shunt). METHODS The shunt vessels were classified by echocardiography as uniformly patent, segmentally stenosed, and u...

WITH the experience of over a quarter of a century of portacaval anastomosis, it has been established that the operation prevents bleeding from oesophageal varices, but there is still some doubt as to the therapeutic value of the procedure. A number of individual randomized controlled trials have failed to demonstrate that either prophylactic or therapeutic portacaval shunt significantly prolon...

Intracranial hydatid disease is rare, with reported incidence of 1-2% of all cases with hydatid disease and most of these cases present in childhood. In this report, we describe four children with primary hydatid disease of the brain. All four patients were diagnosed with cranial Magnetic Resonance Imaging and in direct hemagglutination test for Echinococcus granulosus. Of these four children, ...

Normal-Pressure Hydrocephalus I read with great interest the article by Scollato et al entitled “Changes in Aqueductal CSF Stroke Volume in Shunted Patients with Idiopathic Normal-Pressure Hydrocephalus.” In this study, the authors investigated whether there is a relationship between clinical outcome and changes in aqueductal CSF stroke volume (ACSV) in patients with idiopathic normal-pressure ...

Rhythmic behavioral and biochemical changes have been observed in both human and animal models with hepatic insufficiency. The basis of all these alterations is the principal endogenous pacemaker, the suprachiasmatic nucleus. The aim of this work, therefore, is to determine cytochrome c oxidase activity, a marker of neuronal activity and oxidative metabolism, in this nucleus in rats with portac...

A 4-month-old female Holstein Friesian calf was referred to the Veterinary Teaching Hospital, University of Berne, Switzerland for evaluation of ataxia, weakness, apathy and stunted growth. Clinical examination revealed generalized ataxia, propioceptive deficits, decreased menace response and sensibility. Postmortem examination did not reveal macroscopic changes of major organs. Histologically,...

The transjugular intrahepatic portosystemic shunt (TIPS) represents an important advance in the treatment of complications of portal hypertension. The results from the first 10 TIPS procedures in Arhus are reported. We found, as also documented in other clinical series, that TIPS is more effective in controlling acute haemorrhage than treatment with sclerotherapy and specific medical treatment....

A 22-year-old woman presented with acute left-sided pleuritic chest pain and dyspnea 6 days after surgery for revision of the stenotic central aortopulmonary shunt. She had a history of tetralogy of Fallot (TOF), pulmonary valve stenosis, ventricular septal defect and major aortopulmonary collateral artery. Her Waterston shunt was placed when she was 5 years old and stented and re-dilated after...

Early brain injury and delayed cerebral vasospasm both contribute to unfavorable outcomes after subarachnoid hemorrhage (SAH). Reproducible and controllable animal models that simulate both conditions are presently uncommon. Therefore, new models are needed in order to mimic human pathophysiological conditions resulting from SAH. This report describes the technical nuances of a rabbit blood-shu...

A case of cerebellar tuberculoma, 17 year old girl, presented with complaints of headache, blurring of vision and difficulty in walking. Non-contrast computed tomography of head revealed obstructive hydrocephalus and a hypodense space occupying lesion in cerebellum. Magnetic resonance imaging (MRI) of brain with contrast enhancement revealed large conglomerate cerebellar tuberculomas with obstr...
