The usefulness of electroencephalographic (EEG) monitoring as well as the significance of the period of cross clamping in carotid endarterectomy have not been completely defined. In particular, the clinical importance of major EEG changes has not been fully investigated and some recent studies seem to indicate that the method has little value. As to the(More)
In spite of the availability of the new endovascular technique (GDC) to manage cerebral aneurysms, to date, the crucial question "which is the proper treatment in a given patient?" still remains unsettled. In order to check whether an answer is possible, we retrospectively reviewed a personal series of 192 consecutive patients with cerebral aneurysms(More)
Combined coronary artery bypass and carotid endarterectomy were performed in 52 patients (mean age 61 years) between 1981 and 1990. Of these, 36 (69%) had functional class III-IV angina pectoris, 33 (63%) had triple-vessel disease, 36 (69%) had one, or more, previous myocardial infarctions, and 33 (63%) had an abnormal left ventricular function. In 4 cases,(More)
The authors report 19 consecutive children with cerebral arteriovenous malformations over the period 1978-1992. These patients are compared with a series of 120 consecutive adult patients with the same pathology, managed during the same period. The main clinical and angiographic features, as well as the treatment modalities and outcome are reviewed and(More)
Aneurysms of the vertebro-basilar junction area have been considered the most difficult to be surgically treated because of their deep location, the proximity of the brain stem and the cranial nerves. However, at present, new endovascular techniques and new transbasal surgical approaches offer valuable management strategies. This paper concerns six(More)
Anterior Basal Skull Fractures (ABSFs) may be complicated by Cerebrospinal Fluid (CSF) fistulae and intracranial infections. An initially non-operative management is usually suggested since most fistulae spontaneously stop within a few days thus requiring no surgical repair. However, if the fistula fails to stop or recurs, surgical treatment is to be(More)
Subclavian-cortical middle cerebral artery bypass by saphenous vein interposition is an uncommon recent revascularization technique used for immediate volume flow to the brain or when donor arteries are unavailable or inadequate. We used this technique in four cases of symptomatic common carotid artery occlusion. In the last two cases, severe, reversible(More)
Brain metastases (BrM) are tumours that originate in tissues outside the central nervous system and spread secondarily to involve mainly the brain. The management of patients with cerebral metastases is complex, costly, and in some instances controversial. Furthermore, even in patients with widespread systemic cancer, the symptoms of the disease are often(More)
Two cases of an unusual complication of synthetic duraplasty are reported. In both cases, patients had been operated on because of meningiomas and dural defects had been repaired with Silastic. Some years later they developed severe graft-related haematomas and were ultimately successfully treated only by the removal of the synthetic grafts. On the basis of(More)
OBJECTIVE This report focuses on the surgical management of aggressive intracranial dural arteriovenous fistulae (d-AVFs), which are defined as fistulae with arterialized leptomeningeal veins (red veins). Particular attention is paid to the accurate identification of the venous drainage pattern and to the choice of the proper treatment strategy. METHODS(More)
