[Giant supratentorial intracranial aneurysms. Analysis of 22 cases].

Introduction: Giant intracranial aneurysms represent 2 to 5% of all aneurysms. They are well characterized from the anatomical and clinical point of view. Their natural history shows its potential lethality.

[Aneurysms surgery in the patients aged seventy to eighty years].

Elderly patients are a growing population group in developing countries because of optimal health care. 13% of Cuba population is older than sixty years and it is expected to grow to 20% in 2005. Subarachnoid hemorrhage secondary to ruptured aneurysms in geriatric patients carries a high mortality but a few patients are selected for surgical treatment.

[Ogilvie's syndrome. A report of 3 cases].

Introduction: Lumbar spine surgery represents a common procedure in Neurosurgery. Ogilvie's Syndrome is an infrequent complication of lumbar disc surgery, characterized by acute paralytic ileum as a result of acute colonic dilatation without mechanical obstruction.

Clinical Cases: We present the clinical data, surgical findings and evolution of three patients operated on for large lumbar disc herniation.

[Endocranial hypertension].

Introduction And Objective: The endocranial hypertension syndrome is one of the commonest and most feared neurological complications in clinical practice. This encourages its continued study, and is the subject of this review.

Development: Endocranial hypertension is the common pathway for the presentation of many neurological and non neurological disorders.

[Simultaneous cephalic migration of a ventriculoperitoneal shunt into the intraventricular and subdural spaces. A case report].

Introduction: Hydrocephaly is defined as a hemodynamic disorder in which the production, circulation or reabsorption of cerebrospinal fluid is involved. Migration, in a cephalic direction, into the subdural and intraventricular spaces of the proximal ends (shunt malfunction), is very unusual and perhaps not yet reported. It probably involves movement of the craniospinal region of the patient which leads to a follow on effect due to an underlying disorder.
