Treatment of radiation-induced brachial plexopathy with omentoplasty

Radiation-induced brachial plexus neuropathy (RIBPN) is a rare and delayed non-traumatic injury to the brachial plexus, which occurs following radiation therapy to the chest wall, neck, and/or axilla in previously treated patients with cancer. The incidence of RIBPN is more common in patients treated for carcinoma of the breast and Hodgkin lymphoma. With the improvement in radiation techniques, the incidence of injury to the brachial plexus following radiotherapy has dramatically reduced. The currently reported incidence is 1.2% in women irradiated for breast cancer. The progression of symptoms is gradual in about two-thirds of cases; the patients may initially present with paresthesia followed by pain, and later progress to motor weakness in the affected limb. We present the case of a 68-year-old female patient with breast cancer submitted to surgery, chemotherapy, and radiotherapy in the year 2000. Eighteen years later, she developed symptoms and signs compatible with RIBPN and was successfully submitted to omentoplasty for pain control. Omentoplasty is an alternative treatment for RIBPN refractory to conservative treatment, which seems to be effective in improving neuropathic pain. However, postoperative worsening of the motor strength is a real possibility, and all candidates for this type of surgery must be informed about the risk of this complication.

Fatores preditivos de hidrocefalia crônica em pacientes com hemorragia subaracnoidea por ruptura de aneurisma / Predictive factors for chronic hydrocephalus in patients with aneurismal subarachnoid hemorrhage

Hidrocefalia é uma complicação comum da hemorragia subaracnoidea (HSA) por ruptura de aneurisma e, de acordo com o tempo de aparecimento após o sangramento, pode ser classificada em aguda, subaguda ou crônica. A entidade clínica da hidrocefalia crônica após a HSA está bem estabelecida, porém suas características clínicas e fatores correlacionados são controversos. Os autores discutem sobre os fatores preditivos para hidrocefalia crônica em pacientes com hemorragia subaracnoidea por ruptura de aneurisma e sua correlação com a presença de sangue no líquor, quantidade de sangue visualizada à tomografia após a hemorragia, localização do aneurisma, o efeito de uma drenagem liquórica contínua, ocorrência de hidrocefalia aguda, grau de hemorragia subaracnoidea (classificação de Fisher), o efeito da drenagem das cisternas, alterações na circulação liquórica, ocorrência de vasoespasmo, dentre outros.
