[Influence of anticoagulants on the appearance of chronic subdural hematoma].

In recent years in the Department of Neurotraumatology in Cracow it has been noticed the frequent connection between appearance of chronic subdural hematoma (CSDH) and treatment by anticoagulant medications. The aim of this study is to draw attention to the problem of insufficient control of anticoagulants consumption, especially by patients treated for cardiovascular system diseases that increases the risk of bleeding and CSDH development. The paper is based on data from questionnaires that was sent to patients with CSDH, cured in the Department of Neurotraumatology form 2004 to 2005. Analyzed was the group of 51 patients with chronic subdural hematoma; 37 individuals (72.5%) confirmed taking acetylsalicylic acid in the period of 3 months before admission to the Department, 9 (17.6%) patients answered that they were taking low-molecular weight heparin. One patient (1.9%) was taking chronically derivative of cumarin. The authors would inform that anticoagulant treatment might favour increase of chronic subdural hematoma incidence. It's especially important, because the average life expectancy has been prolonged in Poland and there are more people taking acetylsalicylic acid. This can be an epidemiological problem in future.
