Summary
This is a research study to compare the efficacy of aspirin (acetylsalicylic acid) and pneumatic compression devices versus enoxaparin (also known as Lovenox) and pneumatic compression devices in preventing deep vein thrombosis in patients with pelvic and lower extremity malignant tumors and undergoing surgery. Pneumatic compression devices are also known as sequential compression devices and are inflatable compression sleeves that are placed around patient's legs to reduce the risk of clot formation deep vein thrombosis. Pneumatic compression devices are made of a soft material that wraps around the lower leg and periodically squeeze the calf. A deep vein thrombosis is a blood clot. Most hospitalized patients wear these as a preventive measure. Pneumatic compression devices alone are not sufficient to prevent deep vein thrombosis formation. Therefore, medicines, such as aspirin and enoxaparin are utilized. Both drugs are used for prevention, but there are no studies in patients with musculoskeletal tumors which have determined whether one drug is better than another. The knowledge gained from this study will determine whether aspirin and pneumatic compression devices is the same or better than enoxaparin and pneumatic compression devices in preventing deep vein thrombosis in this patient population and may result in fewer wound and bleeding complications
Eligibility Criteria
Inclusion Criteria
-Scheduled or to be scheduled for surgery performed on neoplasms of the pelvis or lower limbs, including both primary musculoskeletal lesions as well as metastatic lesions; these neoplasms may include major tumor resections, metastatic and pathologic fractures of the hip and lower extremities (LE), open biopsies, and primary malignant tumors; an active malignant neoplasm must be present at the time of surgery
Exclusion Criteria
- Prior history of DVT or PE
- Previously placed vena cava filter
- No detectable malignant disease at the time of operation
- Previous arterial thrombosis (myocardial infarction [MI], cerebral vascular accident [CVA])
- Severe platelet dysfunction (uremia, medications, dysplastic hematopoiesis); excluded if platelets 1.6 & > 35)
- Hypersensitivity or allergy to aspirin or heparin (including those diagnosed with heparin-induced thrombocytopenia)
- Conditions associated with bleeding (active ulcer disease, recent neurosurgery, bleeding disorders)
- Patients with renal insufficiency (creatinine [Cr] > 1.5)
- Pregnant patients
- Epidural anesthesia
