Practical importance of CT scan in the treatment of intracranial aneurysm. Report on one case [LE ROLE PRATIQUE DE LA TDM DANS LE TRAITEMENT DES ANEVRYSMES INTRACRANIENS. A PROPOS D'UN CAS]
No full textThe author reports on a case of MCA aneurysm for which the decision to operate was based above all on the CT examination. In this regard the practical importance of the CT in diagnosis and treatment of subarachnoid hemorrhage (SAH) is again emphasized
Medical treatment of subarachnoid hemorrhage due to rupture of an intracranial saccular aneurysm [LA TERAPIA MEDICA NEL TRATTAMENTO DELL'EMORRAGIA SUBARACNOIDEA DA ROTTURA DI ANEURISMA SACCULARE INTRACRANICO]
No full textThe author has reviewed the problem of conservative care of subarachnoid hemorrhage (SAH) due to ruptured intracranial aneurysms. A retrospective study was performed, comparing two different antifibrinolytic therapeutic modalities, in order to investigate whether one of the two would have led to lower complications rate. 131 patients with recently ruptured intracranial aneurysms were treated according to two different methodics: AMCA, 3 gm/day, combined with Aprotinine, 3-400,000 K.I.U./day; and AMCA, 6 gm/day. Patients of both differently treated groups showed similar rate of rebleeding and of thromboembolic complications, while those treated with the modality 'B' showed a higher rate of ischemic complications and of post-SAH hydrocephalus. The fact that this study is retrospective leads to consider carefully the above results. Nevertheless, there are reasonable preliminaries in order to support a larger use of this modality 'A'. The question of surgical timing is also briefly discussed. In the last years most surgeons were used to operate not less than 8-10 days after SAH. However, recently several authors have supported early surgery, mainly on the basis of pathophysiological considerations. A New Multicenter International Cooperative Study has been organized in order to correlate the results of surgical management of intracranial aneurysms to the interval SAH-operation. This would possible give an important contribution to the clarification of this debated problem
A less-invasive technique for harvesting autologous iliac crest grafts for cervical interbody fusion:technical note
No full textBackground: A new technique for harvesting autologous iliac bone grafts is described. TECHNIQUE: This technique is mainly based on performing carefully a limited subperiosteal dissection, obliquely directed bone cuts, and avoiding the stripiing of the anterior thigh musculature. CONCLUSION: This technique allowed to overcome almost all the problems that can occur when using the traditional technique for iliac crest graft harvesting and was used in over 100 cases of cervical discogenic disease with satisfactory result
Giant, completely thrombosed intracranial aneurysm simulating tumor of the foramen magnum
No full textA 51-year-old man was examined for a suspected tumor of the foramen magnum. A computed tomographic (CT) scan confirmed the presence of a huge mass, which was thought preoperatively to be a neurinoma. At operation, this was revealed to be a giant thrombosed aneurysm of the vertebrobasilar junction that had eluded preoperative angiographic examination. The CT features of this atypical case are discusse
Skull base surgery program of the republic of cuba: establishing a demanding subspecialty in a developing country
Full text linkThe history of the founding of the Cuban Skull Base Surgery Group is reported. Under the author's supervision and coordination, the group has managed more than 100 major skull base cases over a 6 -year period. The mortality rate was 13 € and the rate of permanent morbidity was 23 %. In the last 2 years, the mortality rate decreased to 8%. These result reflect the group's enthusiasm pitted against the obvious challenges associated with economic constraints. The present experience may be instructive for neurosurgeons interested in exporting their expertise, with the goal of helping colleagues in developing countries to broaden their professional experience
Antifibrinolyticsin aneurysmal subarachnoid haemorrhage. A retrospective comparison of two different forms of antifibrinolytic therapy
No full textThe results of two different antifibrinolytic therapeutic modalities (A = AMCA 3gm daily + Aprotinin, 3-400000 K.I.U daily, B=AMCA, 6 gm daily) were compared retrospectively in a series of 137 patients harbouring recently ruptured intracranial aneurysms. The rates for rebleeding and thromboembolic complications were similar in both differently treated groups of patients, whilst that for ischaemic complications was significantly (p<0.025) lower in cases managed with modality A. In these also the incidence of hydrocephalus was decreased, although not significantly (0.20>p >0.19). According to these data, low-dose AMCA + Aprotinin seems to be a rational therapeutic combination for cases of ruptured intracranial aneurysms, in which antifibrinolytics are indicate
Occlusion of the internal carotid artery by intracranial tumors
No full textOcclusion of the internal carotid artery by an intracranial tumor occurs only rarely. Three such cases are reported here. All were parasellar tumors, 2 meningiomas and 1 pituitary adenoma. The occlusion was demonstrated by carotid angiography in all cases. The location of the tumor was demonstrated by a computerized tomographic (CT) scan in 1 case. These 3 cases were encountered in a neurosurgical series of over 4,500 brain tumors and 10,000 angiographic examinations during the period 1952 to 1979
Computed tomography in aneurysms of the vein of galen
No full textTwo cases of aneurysm of the great vein of Gaien are reported. Diagnosis was made by means of computed tomography (CT) and confirmed by angiography. Surgical treatment was successful in one case; surgery was refused in the other case. The value of CT in the diagnosis of these malformations is stressed
Meningioma as a sequel of radiotherapy for pituitary adenoma
No full textTwo cases of meningioma developing after radiation therapy of pituitary adenoma were found among 180 verified adenomas irradiated pre- or post-operatively and followed up for at least five years. Only a few instances of association of meningioma and pituitary adenoma were found in the literature. In patients who did not receive X-ray treatment both tumours were simultaneously verified at operation and/or autopsy, whereas in those who were irradiated a definite time interval, ranging from 11 to 18 years, was present between surgical and/or radiotherapeutic treatment for pituitary adenoma and verification of meningioma. A possible role of radiation in the genesis of these meningiomas is postulated
