INTRODUCTION Distal anterior cerebral artery is the portion of the anterior cerebral artery located distal to the anterior communicating artery. Aneurysms of that territory represent 0.35 - 4.5% of all intracranial aneurysms. MATERIAL AND METHODS 524 patients with intracranial aneurysms were operated on between January 1981 and April 2002. We treated 20(More)
INTRODUCTION Arteriovenous malformations (AVM) of the brain are, at present, entities that are difficult to diagnose owing to the variations in their clinical presentation and the different localisations in the central nervous system. Their most frequent clinical forms are haemorrhage, which is typically located in the intraparenchymatous region, seizures(More)
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(More)
INTRODUCTION Ophthalmic artery aneurysms are infrequent lesions and they have very specific particularities. OBJECTIVE to present the anatomoclinical and surgical characteristic of our patients with ophthalmic aneurysms and to analyze our surgical results. PATIENT AND METHODS 604 patients with intracranial aneurysms were operated on between January 1982(More)
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.(More)

AIM The effectiveness of anatomic localization of the subthalamic nucleus (EAL) was assessed and the mapping method is described here. The symmetry of contralateral nuclei (SCN) was analyzed on 11 parkinsonian patients submitted to bilateral subthalamotomy with ablative lesioning. PATIENTS AND METHODS To assess EAL the percentage so much of first(More)
