A case of subarachnoid hemorrhage caused by a cervical hemangioblastoma is presented. The clinical picture was indistinguishable from that of a subarachnoid hemorrhage from an intracranial lesion. The diagnosis was established by angiography and water-soluble contrast myelography followed by cervical computed tomographic scan. At surgery, the tumor was(More)
INTRODUCTION The management of incidental unruptured aneurysms remains a matter of controversy; middle-sized or large anterior circulation incidental aneurysms, in young or middle age patients, should be considered for treatment. Surgical clipping is an accepted treatment for middle cerebral artery unruptured aneurysms. Ischemic events can occur even in(More)
BACKGROUND Guidelines recommend cerebral perfusion pressure (CPP) values of 50-70 mmHg and intracranial pressure lower than 20 mmHg for the management of acute traumatic brain injury (TBI). However, adequate individual targets are still poorly addressed, since patients have different perfusion thresholds. Bedside assessment of cerebral autoregulation may(More)
OBJECTIVE AND IMPORTANCE This case report illustrates the possible occurrence of intracranial aneurysms after surgery and radiation-induced vasculopathy. CLINICAL PRESENTATION An internal carotid bifurcation aneurysm was diagnosed in a 19-year-old woman in a routine follow-up examination by magnetic resonance imaging 5 years after subtotal removal of a(More)
BACKGROUND Surgery of pineal region lesions is considered a challenging task, due to the particular relationship of lesions in this location with neural and vascular structures. Few series with a significant experience of dealing with these patients have been reported. METHODS We review our experience using infratentorial supracerebellar approach in the(More)
We report the clinical use of galea frontalis myofascial flaps in the treatment of anterior fossa cerebrospinal fluid leaks after trauma. This flap provides an adequately sized and vascularised barrier between the cranial and nasal cavities through which the cells of the inflammatory response reach the target area. This technique was used in 9 cases with(More)
BACKGROUND Vasospasm is a frequent complication of subarachnoid hemorrhage (SAH), implicated in poor outcome, and prediction of its occurrence might be important on the therapeutic approach of this condition. Brain oxygenation in aneurysmal SAH was prospectively monitored during surgery in 28 patients, using brain tissue oxygen pressure (PbtO(2)), studying(More)
Single Photon Emission Computed Tomography (SPECT) after intravenous administration of Technetium-99m hexamethylpropylene-amine oxime (Tc-99m HM-PAO) makes possible the evaluation of cerebral perfusion. We have been assessing the diagnostic accuracy of SPECT in some groups of head trauma patients: the preliminary results of this study are presented.(More)
According to reports in the literature traumatic interhemispheric subdural haematomas (I.S.H.) are supposed to present acutely or subacutely with contralateral monoparesis of a lower extremity or hemiparesis or in bilateral haematomas even with paraparesis, and to need early operative evacuation. In our series of 5 cases none of them followed this(More)
Craniofacial infection is a major problem for the plastic and neurosurgical team. Previous successful experiences with free muscle and omentum flaps and the galea frontalis myofascial flap have been reported, avoiding disastrous complications after frontofacial advancements and the resection of skull base tumors. The authors report the clinical use of the(More)
