[Prevention of TEN in surgery, prolonged thromboprophylaxis]

Deep vein thrombosis (DVT) and its consequences are the most frequent cause of morbidity and mortality in operated patients, in whom the risk factors for its onset are accumulated. In general surgery, its occurrence was confirmed in 10-40% of operated patients with no prophylaxis, while after major orthopaedic procedures, the rate was up to 60% of patients. Prophylaxis is a fundamental element of the whole strategy of all active measures in prevention of thromboembolic complications. The authors present current methodology of TEN prophylaxis, including a long-term administration, which is accepted by most countries and expert societies, across all branches of surgery.
