Influence of Tobacco Smoking on Perioperative Risk of Venous Thromboembolism.

Venous thromboembolism (VTE) is generally considered a process very different from arterial atherosclerosis. The role of tobacco is well known in arterial thrombosis. However, its role in VTE is less obvious and remains controversial. In this mini review, we analysed the literature to identify the role of active or passive smoking in perioperative VTE and the relationship between arterial atherosclerosis and VTE. We carried an Internet search in French and English including the following keywords: deep vein thrombosis, tobacco, cigarette smoking, pulmonary embolism, postoperative, postoperative, atherosclerosis. Regarding the relationship between tobacco and VTE, a total of 9 studies were identified. Studies were ranked by the risk of VTE in relation to active or passive smoking. In conclusion, the management of smoking during the perioperative period for a short-term arrest (minimum 4-8 weeks before the intervention), or long term, allows among others a reduction of arterial or venous thrombotic events. However, it is clear that the training of anaesthesiologists in the management of smoking will contribute to the reduction of this public health problem.
