Background: Postoperative pulmonary embolism (PE) remains a major health concern. The purpose of our study was to evaluate our experience with postoperative PE.
Methods: We retrospectively reviewed the medical records of patients who had a postoperative PE at our institution.
Results: Our study included 115 patients. Prophylaxis was administered preoperatively in 31% of patients and postoperatively in 56% of patients. The diagnosis was obtained by computed tomography scan in 74 patients (64%), ventilation-perfusion scan in 24 patients (21%), angiogram in 8 patients (7%), and other modalities in 9 patients (8%). The time elapsed between surgery and the diagnosis of PE varied significantly by patient age (<40 y: 3 d, compared with 40-60 y: 11 d; P = .02). The majority of patients with PE were treated with anticoagulation (83%). Morbidity and mortality rates both were 9%.
Conclusions: Age has a significant impact on the timing of postoperative PE, with the majority of cases being diagnosed with a computed tomography scan, and treated with anticoagulation.
