ABSTRACT
Objective To analyze 78 cases of brachial plexus injury submitted to the Oberlin technique between 2003 and 2012. The potential complications of this technique were analyzed, especially motor damage or hypoesthesia of the hand. Method Medical records from patients with brachial plexus injuries at the levels of the C5-C6 and C5-C6-C7 vertebrae were retrospectively analyzed. Cases submitted to the Oberlin procedure with or without concomitant brachial plexus procedures between 2003 and 2012 were evaluated. The minimum follow-up period was of 1 year. In addition to the clinical examination, electromyography and magnetic resonance imaging (MRI) of the brachial plexus were used to diagnose and locate the nerve damage. Results A total of 78 surgical patients met the inclusion criteria. Postoperative neurological changes, mostly transient, were observed in 18 patients. Hypoesthesia in the ulnar side of the handwas observed in seven cases; neuropathic pain in five cases; allodynia in four cases, and hand motor loss in two cases. Conclusion Based on the results of the present case series, we conclude that there are few sequelae in the donor nerve territory compared with the benefit of the Oberlin technique on the recovery of elbow flexion after brachial plexus injuries.

A derivação ventriculoperitoneal (DVP) representa uma forma importante e comum de tratamento da hidrocefalia. Entretanto, pode ocorrer uma série de complicações durante a sua instalação ou por causa de seu mau funcionamento, como infecção, obstrução e hiperdrenagem liquórica. Nesse trabalho, descrevemos uma rara complicação em que um paciente submetido à DVP evoluiu com tetraparesia progressiva. Investigação posterior evidenciou hiperdrenagem da válvula, levando a diminuição do retorno venoso intracraniano, dilatação do plexo venoso epidural e consequente compressão medular no nível da junção bulbomedular. Após o diagnóstico, fizemos o ajuste no nível de desempenho da válvula, e o paciente evoluiu com melhora clínica. Concluímos que o conhecimento desse tipo de complicação associada à disfunção de DVP pode levar a um diagnóstico mais precoce e melhor resposta ao tratamento. O tratamento envolve a correção do fator causal, ou seja, a hiperdrenagem...
The ventriculoperitoneal shunt represents an important and common treatment of hydrocephalus. However, there may be a number of complications during installation or due to a malfunction, such as infection, obstruction and overdrainage. In this paper, we described a rare complication in a patient submitted to a shunt who evolved to progressive tetraparesis. Further investigation showed valve overdrainage, leading to a decrease in venous return, intracranial epidural venous plexus dilatation and consequent cord compression at cervicomedullary junction. After the diagnosis, we adjusted the level of performance of the valve and the patient clinically improved. We concluded that the knowledge of this kind of complication related to shunt dysfunction may take to an early diagnosis and a better treatment response. The treatment involves correcting the causative factor which is the overdrainage...

Os aneurismas gigantes intracranianos podem se manifestar de diversas formas. Neste trabalho, relatamos o caso de uma paciente com um aneurisma gigante da artéria cerebral média manifestando-se através da síndrome de Kernohan, raramente encontrada em aneurismas cerebrais. Diagnóstico e tratamento são discutidos.
