Trombose venosa profunda e sua rela？？o com trombofilias e neoplasias: estudo retrospectivo

objectives: evaluation of the results obtained with the application of specific protocols established in the department for screening for thrombophilia and malignancy in patients hospitalized during a period of five years with the diagnosis of deep venous thrombosis (dvt). material and methods: a retrospective study was performed through the review of the clinical files of all patients aged 50 or less hospitalized in our department between january 1st 2006 and december 31st 2010 with that diagnosis, and the results obtained in the protocols were analysed. results: from a total of 89 patients, 64 (71,9%) were females and 25 (28,1%) were males, and the mean age was 33,3 ±10,0 years. 14,6% of the patients had already had, at least, one previous episode of deep venous thrombosis and 78,7% had, at least, one risk factor. the protocol for screening for thrombophilia and malignancy was applied to 65 patients (73,0%), being detected congenital thrombophilias in 41 patients (63,1%), two cases of antiphospholipid antibody syndrome (aps), one case of monoclonal gammopathy, one of lung cancer and one of sacral chordoma. 49 of the patients subjected to the protocols (75,4%) were referred to the hematology clinic for evaluation and in 40 of those patients (81,6%) was suggested keeping oral anticoagulation for more than 12 months. conclusions: given the high prevalence of genetic polimorphisms that confer a higher thrombotic risk and the not rare cases of aps and of occult malignancies present in this population, it is considered that, despiste its elevated costs, the screening for these kind of pathologies should continue to be done.
