    Notes: Summary Numerous surgical procedures have been proposed for treatment of syringomyelia associated with Chiari I malformation, but the optimal treatment has not yet been uniformly standardised. The main aim of the surgical treatment of syringomyelia/Chiari I complex is directed toward restoration of physiological cerebrospinal fluid dynamic at the craniovertebral junction. We report the surgical results of eight patients, affected by syringomyelia and Chiari I malformation, age range from 18 to 62 years, treated by bony foramen magnum decompression combined with transverse microincisions of the outer layer of the dura mater. In an average postoperative follow-up period of two years neurological symptoms and signs improved in seven patients. Postoperative Magnetic Resonance showed a decrease in size of the syrinx in seven patients. These results suggest that foramen magnum decompression combined with transverse microincisions of the outer layer of the dura 1) is an effective and safe treatment option for syringomyelia and Chiari I malformation, 2) corrects the circulatory disturbances of cerebrospinal fluid dynamic, 3) leads to a decrease in size of the syrinx and to a significant improvement in neurological signs and symptoms, 4) avoids complications of intradural approaches and syringosubarachnoid shunting.

    Notes: Summary  This is the first case of multiple (triple) pituitary micro-adenomas documented by magnetic resonance imaging (MRI) in a living patient and treated by a transsphenoidal microsurgical approach. The patient, a 37-year-old woman, complained of a long history of bifrontal headache, weight gain and oligomenorrhea. Physical examination revealed moderate hirsutism and a slight fat pad overlying the vertebrae. Routine laboratory studies and endocrinological biochemical investigations were normal. A gadolinium-enhanced MRI of the pituitary region revealed three intrapituitary micro-adenomas. A transsphenoidal microsurgical approach to the pituitary gland was carried out and micro-adenomas were completely removed one at a time. One year follow-up showed complete resolution of clinical symptoms and signs and normal biochemical parameters of pituitary function.

    Notes: Summary An experimental model was used to investigate acute alterations of cerebral metabolic activity in rats subjected to subarachnoid haemorrhage (SAH). Haemorrhages were produced in anaesthetized animals by injecting 0.3 ml of autologous, arterial nonheparinized blood into the cisterna magna. Control rats received subarachnoid injections of mock-cerebrospinal fluid to study the effect of sudden raised intracranial pressure, or underwent sham operation. Three hours after SAH rats were given an intravenous injection of [14C]-2-deoxyglucose. Experiments were terminated by decapitation, and the brains were removed and frozen. Regional brain metabolic activity was studied by quantitative autoradiography. In comparison with sham-operated controls, cerebral metabolic activity was diffusely decreased after SAH. Statistically significant decreases in metabolic rate were observed in 23 of 27 brain regions studied. Subarachnoid injections of mock-cerebrospinal fluid also produced depression of cerebral metabolic activity, but quantitatively these changes were not as pronounced and diffuse as in SAH rats. The present study shows that a widespread depression of brain metabolism occurs in the acute stage after experimental SAH and is probably secondary to the Subarachnoid presence of blood itself and/or blood products.

    Does Subarachnoid Blood Extravasation per se Induce Long-Term Neuropsychological and Cognitive Alterations? (1998)

    Notes: Summary  Although recent advances in medical and management strategies have reduced the mortality and morbidity rates related to subarachnoid haemorrhage (SAH), patients who survive a SAH may remain nevertheless affected by persistent cognitive and neuropsychological disturbances. The presence of these deficits has been attributed to the neurotoxic effects of the widespread subarachnoid blood. To assess the long-term neuropsychological and cognitive outcome related to subarachnoid blood extravasation per se we evaluated 20 patients affected by an unknown origin subarachnoid haemorrhage, and having SAH characteristics generally considered predictive of a favourable outcome. Patients were enrolled after a one-year interval from the initial insult, and were selected accordingly to a pre-designed protocol. We employed a complete battery of tests, assessing general cognitive and language functions, memory and construction ability, attention and vigilance, anxiety and depression. The results were compared with normal reference values and with performances of a socio-demographically homogenous sample of control volunteers. This study did not evidence any significant long-term cognitive and neuropsychological alteration after subarachnoid blood extravasation. These results indicate that the presence of subarachnoid blood initiate a number of secondary mechanisms of pathology.

    Relation of cerebral vasospasm to operative findings of subarachnoid blood around ruptured aneurysms (1982)

    Notes: Summary An investigation was carried out in 28 patients in order to evaluate the relationship between angiographically documented vasospasm, amount of subarachnoid blood found at surgery around ruptured intracranial aneurysms, and delayed ischaemic deficits. Angiography was performed at time intervals ranging between 5 and 17 days, and surgery not later than 21 days following subarachnoid haemorrhage. The absence of subarachnoid clots was associated in ten patients, with no or minor vasospasm and no or mild neurological deficits. Thin clots were found in eight patients; one of them had no vasospasm, six had minor vasospasm, and one showed severe vessel narrowing. Major clinical signs were absent in these cases. All ten patients with thick clots developed severe vasospasm, and eight of them severe neurological signs. The important aetiological role of local subarachnoid clots in determining vasospasm is emphasized in view of surgical timing.

    Neuroradiological findings in multiloculated hydrocephalus (1982)

    Notes: Summary The characteristic neuroradiological features of multiloculated hydrocephalus following neonatal meningitis and ventriculitis in five infants are presented. The role of ventriculography and computerized tomography in detecting multi-loculated and enlarged ventricles and paraventricular cavities, as well as complete and incomplete septa, is emphasized for early diagnosis and surgical management. CT scan also provides clues indicating the presence of thin but not visualized septa. It is suggested that post-meningitic hydrocephalus should be repeatedly followed-up for detection of multiloculated transformation. Probably this entity occurs less uncommonly than was thought in the past. The CT scan appears the most helpful and safe procedure for the serial evaluation, but ventriculography may be usefully combined with it in order to plan the most suitable operative approach for fenestration of membranes.

    Notes: Summary ¶ An increase in blood-brain barrier (BBB) permeability after subarachnoid haemorrhage (SAH) has been described in humans and has been correlated with delayed cerebral ischemia and poor clinical outcome. Few studies examined in the laboratory the relationship between SAH and BBB, with contrasting results due to limitations in experimental probes adopted and in timing of observation. The aim of this study was to quantify the time-course of BBB changes after experimental SAH. Groups of eight rats received injections of 400 μl of autologous arterial blood into the cisterna magna. BBB was assessed 6, 12, 24, 36, 48, 60, and 72 hours after SAH and in sham-operated animals separately for cerebral cortex, i.e. frontal, temporal, parietal, occipital, subcortical gray matter (Caudate-Putamen-Thalamus), cerebellar cortex and nuclei, and brain stem by a spectrophotofluorimetric evaluation of Evans Blue dye extravasation. As compared to sham-operated controls, SAH determined a significant BBB permeability change beginning 36 hours after SAH, peaking at 48 hours, and normalizing on day 3. This study provides a quantitative description of the temporal progression and recovery of BBB dysfunction after SAH. These results have implications for the management of aneurysm patients and for assessing the rationale and the therapeutic window of new pharmacological approaches.
