Spinal subdural hematoma after lumbar discectomy without dural injury - Is it possible? A case report and literature review.

BACKGROUND: Spinal subdural hematoma (SSDH) is a rare complication of lumbar discectomy. Here, the authors reviewed 10 articles concerning the etiology, clinical, diagnostic, and surgical management of SSDH. CASE DESCRIPTION: A postoperative SSDH occurred following a lumbar microdiscectomy in an 80-year-old patient in the absence of a dural injury. CONCLUSION: SSDH is a rare complication of lumbar discectomy and may even occur without a dural fistula. Notably, magnetic resonance is the diagnostic study of choice to identify this pathology that may then be appropriately managed.

[Effectiveness of methylprednisolone in the acute phase of spinal cord injuries--a systematic review of randomized controlled trials]. / Efetividade da metilprednisolona na fase aguda do trauma raquimedular--revisão sistemática dos ensaios clínicos randomizados.

UNLABELLED: Steroid therapy has been tested as a protector in spinal cord injury. Multicenter studies evaluating the methylprednisolone (MP) in post traumatic neurological recovery have shown promising results according to NASCIS. A large number of critical studies related to the NASCIS results have been published. OBJECTIVE: To review literature related to use of methylprednisolone compared with placebo. METHODS: This analysis added the average improvement achieved in groups of patients who used MP and placebo (PL) to the average scores of groups at baseline, before treatment, resulting in the final neurological outcome for both groups. RESULTS: The motor score of the MP group was only 2.5 points higher than the PL in a one year follow-up. In neurologically intact patients, the total score is 70 points. Improvement in sensitive scores was also discrete (1.1 and 1.7 points for the pinprick and light touch respectively). A high rate of complications was observed in a group of patients about 60 years old who used MP. CONCLUSION: Differences in the clinical magnitude of benefit obtained (not confirmed by other studies) with the use of MP or PL are not significant, in comparison with the potential for complications when using methylprednisolone.

A corticoterapia tem sido testada como protetor neuronal no trauma. Os estudos multicêntricos avaliando a metilprednisolona (MP) na recuperação neurológica após trauma revelaram-se promissores (NASCIS). Porém, várias, críticas às suas metodologias foram publicadas. OBJETIVO: Revisar a literatura relacionada ao uso da metilprednisolona comparada com placebo. MÉTODOS: A análise feita somou a média da melhora obtida nos grupos de pacientes que usaram MP e placebo (PL) à média dos escores dos grupos na linha de base, antes de tratamento, obtendo-se o resultado neurológico final de ambos os grupos. RESULTADOS: O escore motor do grupo MP foi apenas 2,5 pontos maior que o PL em um ano de seguimento. O escore motor em indivíduos intactos é de 70 pontos. A melhora nos escores sensitivos foi igualmente discreta (1,1 e 1,7 pontos para sensibilidade a picadas e tato respectivamente). A taxa de complicações observada em grupo de pacientes em torno de 60 anos foi alta com o uso de MP. CONCLUSÃO: As diferenças na magnitude do benefício clínico obtido (não confirmado por outros estudos) com o uso da MP e com o PL não são significativas em confronto com o potencial de complicações do uso da medicação.
