Summary
Deep vein thrombosis (DVT) incidence was low in orthopaedic oncology lower limb surgery patients without prophylaxis. Further studies are needed to confirm these findings and identify specific risk factors for DVT.
Area of Science:
- Orthopaedic Surgery
- Oncology
- Vascular Medicine
Background:
- Deep vein thrombosis (DVT) is linked to malignancy and orthopaedic surgery.
- Orthopaedic oncology patients may face elevated risks for thromboembolic events.
- This patient group receives less attention compared to hip and knee replacement patients.
Purpose of the Study:
- To determine the incidence of DVT in lower limb orthopaedic oncology surgery patients.
- To identify risk factors associated with DVT in this population.
- To assess the need for a larger clinical trial.
Main Methods:
- Prospective study of 38 patients undergoing lower limb orthopaedic oncology surgery without DVT prophylaxis.
- Demographic data, diagnosis, and surgical details were recorded.
- DVT surveillance via ultrasound Doppler pre-operation and two weeks post-operation.
Main Results:
- Two patients (5%) developed DVT, both asymptomatic with proximal thrombosis.
- One patient (2.6%) was diagnosed with asymptomatic, non-fatal pulmonary embolism (PE).
- No statistical analysis was performed due to the small sample size.
Conclusions:
- The incidence of DVT in orthopaedic oncology lower limb surgery patients appears low, even without prophylaxis.
- Larger studies are required to validate these findings and pinpoint risk factors.
- This pilot study suggests a need for further investigation.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
