Risk factors of venous thromboembolism in patients with benign and malignant musculoskeletal tumors: a dual database analysis.

Abstract

Venous thromboembolism (VTE) is a potentially life-threatening condition associated with both orthopaedic surgery and tumour growth. In this study, we identify risk factors associated with VTE in patients with musculoskeletal tumours using two national datasets. The ACS-NSQIP and NIS databases were queried for patients undergoing surgery with a diagnosis of benign or malignant musculoskeletal tumours. Chi-square and binary logistic regression analyses were used to determine risk factors for VTE. The incidence of VTE was 2% in both databases. Patients with malignant tumours, those with tumours of the pelvis, sacrum, or coccyx, obesity, arrhythmias, paralysis, metastatic disease, coagulopathy, and recent weight loss were at increased risk for VTE. In patients with benign tumours, those who were African American, those with tumours of the pelvis, sacrum, or coccyx, diabetes, anaemia, and coagulopathy were at increased risk of VTE. Patients with malignant or benign lesion are at greater risk of VTE if they are age 30 and over, of the African American population, or with tumors of the pelvis/sacrum/coccyx, or any of the following comorbidities: pulmonary disease, paralysis, other neurological disorders, or coagulopathy.
