Abstract

Twenty-four adult cases of suspected normal pressure hydrocephalus (NPH) after subarachnoid hemorrhage (SAH) were investigated clinically from the aspect of predicting the efficacy of the shunting procedure. They consisted of 13 men and 11 women, with the mean age of 55-y-o. In addition to checking neurological signs, pre- and postoperative CT scans, RI (or CT) cisternography and bolus infusion test were performed in each of them. Shunt surgery was done, all of which ventriculoperitoneal shunt, in 17 patients. They were divided into three groups, namely, shunt effective group (A), neurologically unchanged group after surgery (B) and worsened group (C). The A group had 8 cases, B had 8 also and C contained only one. Effectiveness of shunt procedure was measured by an improvement in the activity of daily life (ADL). Compared with group B, group A tended to have more cases of delayed onset of NPH (mean days of 112 from SAH attack in group A while 55 days in group B), cases with "trias" (3 against 0) and moderate ventricular dilatation with periventricular lucency (8 against 2). The finding of delayed clearance in cisternogram did not make an accurate judgement in the efficacy of shunt surgery. By using the bolus method of infusion...Continue Reading

Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia is a congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the right ventricle wall and loss of myocardial cells. Primary injuries usually are at the free wall of the right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.
