    Abducens nerve palsy as a postoperative complication of minimally invasive thoracic spine surgery: a case report
    (2016) SANDON, Luiz Henrique Dias; CHOI, Gun; PARK, EunSoo; LEE, Hyung-Chang
    Background: Thoracic disc surgeries make up only a small number of all spine surgeries performed, but they can have a considerable number of postoperative complications. Numerous approaches have been developed and studied in an attempt to reduce the morbidity associated with the procedure; however, we still encounter cases that develop serious and unexpected outcomes. Case Presentation: This case report presents a patient with abducens nerve palsy after minimally invasive surgery for thoracic disc herniation with an intraoperative spinal fluid fistula. A literature review of all cases related to this complication after spine surgery is included. Despite the uncommon nature of this type of complication, understanding the procedure itself, the principle occurrences and outcomes following the procedure, the physiopathogical features of abducens nerve palsy, and the possible adverse effects of spinal surgery, including minimally invasive procedures, can enable an early diagnosis of complications and facilitate the procedure. Conclusions: In spite of being very rare and multifactorial, uni- or bilateral abducens nerve paralysis carries significant morbidity and can occur as a postoperative complication after conventional or minimally invasive spine surgery. This condition requires an accurate diagnosis and adequate multidisciplinary follow up.

    Monoblock external ventricular drainage system in the treatment of patients with acute hydrocephalus: A pilot study
    (2014) ANDRADE, Almir Ferreira de; PAIVA, Wellingson Silva; NEVILLE, Iuri Santana; NOLETO, Gustavo Sousa; ALVES JUNIOR, Aderaldo; SANDON, Luiz Henrique Dias; BOR-SENG-SHU, Edson; AMORIM, Robson Luis; TEIXEIRA, Manoel Jacobsen
    Background: Infection is a major complication in patients undergoing external ventricular drainage (EVD). Our study aimed to evaluate the incidence of infection in a series with the monoblock EVD system. Material/Methods: 46 patients treated with EVD at our emergency department were analyzed prospectively to research the incidence of infections with a new EVD system. Results: The average rate of infection was 8.7%. When we stratified the patients according to the exclusive use of EVD without craniotomies, we identified a reduction in the overall incidence of ventriculitis from 8.7% to 2.3%. Age, etiology, and the presence of ventricular bleeding were not statistically significant risk factors. Conclusions: Despite the small sample examined in this study, we believe that the monoblock system is a simple, inexpensive device that reduces accidental disconnection of the system.
