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)
Intracranial dural arteriovenous fistulas (AVFs) have been recognized as acquired lesions that can behave aggressively depending on the pattern of venous drainage. Based on the type of venous drainage, they can be classified as fistulas drained only by venous sinuses, those drained by venous sinuses with retrograde flow in arterialized leptomeningeal veins,(More)
The standard treatment of foraminal syringomyelia includes foramen magnum decompression and duraplasty. Improvement or stabilization of the disease are achieved in most of cases. However, at least one third of patients are reported to receive little or no benefit. In this paper we retrospectively reviewed a series of 40 consecutive foramen magnum(More)
Traumatic injuries of the craniovertebral junction (CVJ) area are common and frequently the outcome of motor vehicle accidents, falls, and diving accidents. To define and characterize CVJ traumatic injuries, some international classifications are currently in use, and they are thought and focused on junction bone fracture. However, recent data point out a(More)
BACKGROUND Intracranial cysts containing cerebrospinal fluid (CSF) may be developmental or acquired. OBJECTIVE To analyze the results of endoscopic neurosurgery in the management of intracranial CSF cysts. METHODS In a 7-year period, 64 consecutive patients underwent endoscopic neurosurgery for CSF cysts. Group 1 consisted of 13 patients with acquired(More)
10 patients suffering from intracranial aneurysm causing subarachnoid hemorrhage (SAH) have been treated during the acute pre-and postoperatory phase with omega-aminocaproic acid. The blood and the cerebrospinal fluid of the treated patients have been analyzed in order to study fibrin(ogen) degradation products (FDP) and fibrinolytic activity (FA). The(More)
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)
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)
Delayed complications of ethmoid fractures are considered relatively rare. However, meningitis, recurrence of previously ceased cerebrospinal fluid rhinorrhea and delayed onset of cerebrospinal fluid rhinorrhea are possible even years after trauma. We report 10 consecutive patients with delayed complications of ethmoid fractures, whom we treated over the(More)
