Occlusive hydrocephalus caused by a fourth ventricle arachnoid cyst.

The case history of a woman with occlusive hydrocephalus caused by a fourth ventricle cyst is presented. She had slowly progressive complaints and symptoms--concentration and memory disturbances, low-tempered mood, then slight dizziness, loss of appetite and progressive headache--transitorily misinterpreted for signs of depression. She had been treated by psychotherapy and antidepressants for months.

[Effectiveness and safety of intraventricular fibrinolysis in secondary intraventricular hemorrhages (a prospective, randomized study)].

Background And Purpose: Intraventricular clot secondary to brain hemorrhage has still one of the worst prognosis among all stroke subtypes, regardless of conservative therapy or surgical interventions. The rapid clot resolution with thrombolytic agents could improve the outcome by restoring the impaired cerebrospinal fluid circulation, for this reason, the authors examined the safety and efficacy of Urokinase therapy in a randomized, controlled study.

Methods: They enrolled 27 patients with severe intraventricular hemorrhage between 1998 and 2002.

[Thrombolytic therapy in acute ischemic stroke with streptokinase].

Aim And Methods: In an open, observational study, 40 consecutive ischemic stroke patients eligible for thrombolytic therapy using the combined ECASS/NINDS inclusion criteria have been treated intravenously with 1.5 M units of streptokinase. The therapeutic window was 3 hours or shorter.

[MR investigations in stroke].

In the article digital imaging methods are presented with special emphasis on the use on diagnostics of cerebral circulation studies. Recently, fundamental changes have happened in this field, concerning especially the MR investigations. These changes have influenced the therapeutic strategies of ischaemic stroke.
