ABSTRACT

Intracranial pressure monitoring has become critical for the adequate management of patients with severe head injury in recent years. Several other recommendations for intracranial pressure monitoring have also been described, specially for patients with subarachnoid hemorrhage with ventricular enlargement, and spontaneous intracerebral hematomas. The immediate postoperative period of elective surgeries that require brain retraction is another instance where intracranial pressure monitoring could provide useful informations to optimize outcome. Expensive methods make it almost prohibitive to smaller centers in our Country. We describe our protocol of routine intracranial pressure monitoring using an intraventricular catheter connected to an external strain gauge transducer adapted to an ordinary invasive pressure monitor, in a countryside university hospital, and analyze the data of intracranial pressure and cerebral perfusion pressure obtained with regards to outcome and also investigate the more common complications of the method. We conclude that intracranial pressure monitoring could be safely applied at a low cost to improve the management of those patients.

ABSTRACT

The authors present the preliminary results of 20 patients selected to be operated on between January 1996 and April 1997. These patients presented one of the present indications for stereotactic posteroventral pallidotomy (PVP), such as: rigidity, akinesia/bradykinesia, gait dysfunction, drug induced dyskinesias and tremor. Every patient of this protocol was evaluated by: UPDRS score, Schwab and England scale, Hoehn and Yahr Staging Scale before and after surgery. The results in 3 months showed a remarkable improvement after PVP (P<0.01) in all functional assessments, except for facial expression, speech and posture. The morbidity was 5 per cent. 5 patients (25 per cent) who were in Hoehn and Yahr 5 underwent a bilateral simultaneous PVP. In 5 patients (25 per cent), who had tremor, during the PVP, VIM thalamotomy was added. These preliminary results suggest that PVP is highly effective for PD symptoms.

ABSTRACT

Em 44 biópsias estereotáxicas, guiadas por imagem, no período de agosto-1995 até março-1997, as lesoes encontradas foram (ordem de frequência): gliomas (glioblastoma multiforme o mais comum), linfoma primário e demais lesoes ligadas à síndrome da imunodeficiência adquirida, metástases, vasculites, cisto aracnóideo, doença de Creutzfeldt-Jakob, nódulo fibroglial calcificado. A idade variou de 1 a 83 anos. 41 lesoes eram supratentoriais, 2 infratentoriais e uma da calota craniana. A mortalidade foi nula e a morbidade 2,3 por cento. A literatura é revista. Os autores concluem que este procedimento é seguro e eficaz.

ABSTRACT

Estudo prospectivo mostrando a importância da biópsia cerebral estereotáxica no manuseio do paciente com AIDS e que apresenta sintomatologia neurológica confirmada através de imagens. Todos estes pacientes obedecem a escalonamento terapêutico e, depois de terem sido dados os passos prévios, a biópsia passa a ser indicada visando ao diagnóstico etiológico adequado. O protocolo foi iniciado em agosto-1995 e concluído em dezembro-1996. Vinte pacientes foram biopsiados. Nosso protocolo é semelhante ao descrito por Levy e col. (Chicago IL, USA). Linfoma primário foi o diagnóstico predominante, seguido de leucoencefalopatia multifocal progressiva, toxoplasmose e leucoencefalopatia pelo HIV. Um caso de linfoma de células gigantes diplóico foi incluído. Nossa morbi/mortalidade foi nula. Por esta amostragem é possível concluir que a biópsia cerebral estereotáxica é um procedimento seguro e eficaz em pacientes com AIDS.
