RESUMO
BACKGROUND: In high-risk patients, common prophylaxis may be insufficient to prevent thromboembolic events after orthopaedic procedures. In this scenario, a retrievable vena cava filter (VCF) could be considered as an alternative, although it's use remains controversial. Therefore, we asked: (1) what is the overall mechanical complication rate associated with the use of retrievable VCFs in orthopaedic surgery?, (2) what is the association with thromboembolic disease (TED) recurrence, post-thrombotic syndrome and/or major bleeding according to different surgical characteristics?, (3) What is the overall mortality rate attributed to VCF use? METHODS: We retrospectively analyzed a cohort of 68 patients who underwent orthopaedic surgery with a previous diagnosis of TED, in whom a retrievable VCF was placed. Permanent filters were excluded. We studied the filter's mechanical complications and considered as possible outcomes death and 3 hematologic complications: TED recurrence, post-thrombotic syndrome and major bleeding. To estimate association with risk factors, we subclassified surgeries into 5 groups: 1, arthroplasty/non-arthroplasty; 2, primary/revision; 3, elective/urgent; 4, oncologic/non-oncologic; 5, preoperative/postoperative filter. RESULTS: Mechanical complications were 16% and required a filter revision. Sixty-four percent of the revised VCFs developed a mechanical failure and could not be retrieved. Overall prevalence of TED recurrence, post-thrombotic syndrome and hemorrhage was 33%, 15% and 4.5%, respectively. Spinal surgeries were a risk factor for developing TED recurrences. Only 4% of patients died of a TED recurrence. CONCLUSIONS: Orthopaedic procedures had a high risk of mechanical and hematologic complications after using a retrievable VCF. However, mortality was low due to these complications.

OBJETIVO: Avaliar a taxa de mortalidade em um ano e fatores pré-operatórios correlacionados em pacientes com fratura do quadril. MÉTODOS: Os autores estudaram, prospectivamente, 202 de um total de 376 pacientes com diagnóstico de fratura do quadril, que foram admitidos no Hospital Cristo Redentor entre outubro de 2007 e março de 2009. A montagem do banco de dados com análise do perfil epidemiológico foi realizada durante a internação e os dados de seguimento preferencialmente por telefone. RESULTADOS: A taxa de mortalidade total após um ano de seguimento foi de 28,7% ou 58 óbitos, dentre os quais 11 (5,45%) ocorreram na internação. As fraturas foram mais prevalentes em mulheres (71,3%) e pouco comuns em negros (5%). Dentre as comorbidades, demência e depressão apresentaram uma redução estatisticamente significante da sobrevida, (p de 0,018 e de 0,007, respectivamente). CONCLUSÃO: A taxa de mortalidade após um ano de seguimento foi de 28,7%. A demência e a depressão aumentaram esta taxa.
OBJECTIVE: To evaluate the mortality rate at one year and preoperative correlated factors in patients with hip fractures. METHODS: We studied prospectively, 202 of a total of 376 patients with hip fracture who were admitted to the Hospital Cristo Redentor, between October 2007 and March 2009. The assembly of the database with the epidemiological analysis was performed during hospitalization and follow up data preferably by phone. RESULTS: The overall mortality rate after one year of follow-up was 28.7% or 58 deaths, among which 11 (5.45%) occurred during hospitalization. The fractures were more prevalent among women (71.3%) and less common in blacks (5%). Among the comorbidities, dementia and depression showed a statistically significant reduction in survival (p of 0,018 and 0,007, respectively). CONCLUSION: Mortality rate after one year of follow-up was 28,7%. Dementia and depression increased this rate.
