Abstract:
The present study aimed to identify the incidence and risk factors of symptomatic pulmonary embolism and evaluate the safety of early intermittent pneumatic compression application in patients with deep venous thrombosis (DVT) after joint surgery. A total of 144 patients with DVT undergoing joint surgery were divided into two groups according to the appearance of symptomatic pulmonary embolism. Venography and computed tomographic pulmonary angiography were utilized as the assessment methods. The total incidence of symptomatic pulmonary embolism was 0.39% after joint surgery. However, the prevalence increased to 3.5% when computed in patients with DVT. Patients with symptomatic pulmonary embolism were older than those without symptomatic pulmonary embolism (69 ± 4 versus 61 ± 15 years, P = 0.04). The occurrence rate of symptomatic pulmonary embolism in patients with diabetes mellitus was much higher than that in the patients without diabetes mellitus (40.0% versus 8.6%, respectively, P = 0.02). The prevalence of symptomatic pulmonary embolism after joint surgery in patients with DVT was not distinctive. Increased age and diabetes mellitus put patients with DVT at risk of suffering symptomatic pulmonary embolism after joint surgery. In addition, early postoperative application of intermittent pneumatic compression was safe in these patients.
