Purpose: Pulmonary embolism (PE) most commonly results from lower extremity deep vein thrombosis (DVT) and PE is potentially life-threatening. But the risk factors for PE with lower extremity DVT have not been known clearly. We investigated predictive factors of PE combined with DVT in two hospitals.Materials and Methods: From January 2010 to December 2012, 428 patients were diagnosed lower extremity DVT with or without PE. We retrospectively reviewed the medical records of these patients. Characteristics of patients, details of DVT lesions and laboratory findings associated with hypercoagulability were analyzed as risk factors for PE combined with DVT. Results: 238 patients (55.6%) were diagnosed lower extremity DVT without PE and 190 patients (44.4%) were diagnosed lower extremity DVT with PE. There were 84 patients with symptomatic PE (19.6%). The mean age of patients was 66.17±12.88 in DVT without PE, 64.78±14.53 in DVT with PE (p=0.304). Any laboratory findings associated with hypercoagulability were not statistically different between two groups. In univariate analysis, immobilization was revealed as indicator of PE combined with DVT (p=0.032). The patients with cerebral vascular accident showed a lower incidence of PE compared with the patients without cerebral vascular accident (p=0.033). In multivariate logistic regression analysis, immobilization also retained statistically significance for PE combined with DVT (OR=1.551, 95% CI 0.999-2.408, p=0.050).Conclusions: The results of our study suggest that immobilization is useful the independent predictive factor of PE combined with DVT.
