ABSTRACT

OBJECTIVE: Pulmonary embolism (PE) is an important complication of major orthopedic surgery. The aim of this study was to evaluate the incidence of venous thromboembolism (VTE) and factors influencing the development of VTE in patients undergoing major orthopedic surgery in a university hospital. METHODS: Patients who underwent major orthopedic surgery (hip arthroplasty, knee arthroplasty, or femur fracture repair) between February of 2006 and June of 2012 were retrospectively included in the study. The incidences of PE and deep vein thrombosis (DVT) were evaluated, as were the factors influencing their development, such as type of operation, age, and comorbidities. RESULTS: We reviewed the medical records of 1,306 patients. The proportions of knee arthroplasty, hip arthroplasty, and femur fracture repair were 63.4%, 29.9%, and 6.7%, respectively. The cumulative incidence of PE and DVT in patients undergoing major orthopedic surgery was 1.99% and 2.22%, respectively. Most of the patients presented with PE and DVT (61.5% and 72.4%, respectively) within the first 72 h after surgery. Patients undergoing femur fracture repair, those aged ≥ 65 years, and bedridden patients were at a higher risk for developing VTE. CONCLUSIONS: Our results show that VTE was a significant complication of major orthopedic surgery, despite the use of thromboprophylaxis. Clinicians should be aware of VTE, especially during the perioperative period and in bedridden, elderly patients (≥ 65 years of age). .


OBJETIVO: A embolia pulmonar (EP) é uma complicação importante de cirurgia ortopédica de grande porte. Este estudo visou avaliar a incidência de tromboembolismo venoso (TEV) e os fatores que influenciam o desenvolvimento de TEV em pacientes submetidos a cirurgia ortopédica de grande porte em um hospital universitário. MÉTODOS: Pacientes submetidos a cirurgia ortopédica de grande porte (artroplastia de quadril, artroplastia do joelho ou reparação de fratura de fêmur) entre fevereiro de 2006 e junho de 2012 foram incluídos retrospectivamente no estudo. As incidências de EP e de trombose venosa profunda (TVP) foram avaliadas, assim como os fatores que influenciaram sua ocorrência, tais como o tipo de cirurgia, idade e comorbidades. RESULTADOS: Foram revisados os prontuários médicos de 1.306 pacientes. As proporções de artroplastia do joelho, artroplastia de quadril e reparação de fratura de fêmur foram, respectivamente, de 63,4%, 29,9% e 6,7%. A incidência cumulativa de EP e TVP nos pacientes submetidos a cirurgia ortopédica de grande porte foi, respectivamente, de 1,99% e 2,22%. A maioria dos pacientes apresentou EP e TVP (61,5% e 72,4 %, respectivamente) nas primeiras 72 h após a cirurgia. Pacientes submetidos à reparação de fratura de fêmur, aqueles com idade ≥ 65 anos, e pacientes acamados tinham um risco maior de desenvolver TVP. CONCLUSÕES: Nossos resultados demonstram que o TEV foi uma complicação importante de cirurgia ortopédica de grande porte, apesar da utilização de tromboprofilaxia. Os médicos clínicos devem estar alerta para a ocorrência ...
