BACKGROUND: The aim of this study was to analyze the incidence of lower limb deep venous thrombosis (DVT) and the corresponding coagulation status in severe patients after thoracic surgery. METHODS: Severe patients after thoracic surgery who received mechanical prophylaxis of lower limb DVT between July 2016 and June 2018 were analysed retrospectively. Their general information, disease species, surgical treatment, and coagulation index were reviewed. RESULTS: Fifty patients were finally included. There were 34 male and 16 female, aging from 22 to 80 years. The incidence of DVT was 22.0%, all of them were isolated calf DVT. The incidence was 29.4% in male patients, while 6.3% in female; 23.5% in malignant diseases and 18.6% in benign. All coagulation index presented no statistical difference between patients with and without DVT, except activated partial thromboplastin time (APTT). CONCLUSIONS Even on the basis of adequate mechanical prophylaxis, lower limb DVT is common in severe patients after thoracic surgery. Meanwhile, male patients and malignant diseases are more suscepted.
