Determination the relative frequency of lower limb deep vein thrombosis risk factors in patients referred to teaching hospitals in Yasuj city from 2013 to 2014

Aims: Deep vein thrombosis (DVT) is one of the common cardiovascular diseases caused by the formation of clots in deep veins. The aim of this study was to determine the relative frequency of the risk factors of lower limb deep vein thrombosis in patients referred to teaching hospitals in Yasuj city from 2013 to 2014. Methods: In this cross-sectional study, 277 cases of DVT patients who were hospitalized in teaching hospitals of Yasuj city were included in the study. Then, patients' characteristics include age, sex, heart disease, kidney disease, smoking, congenital coagulation problems, history of DVT, use of oral contraceptives (OCP), history of cancer, limb fracture without surgery, diabetes, liver disease, blood pressure, use of catheter and length of stay in ICU were collected using a checklist. Results: The results of the study showed that 50.9% of DVT patients were women and 49.1% were men, and there was no statistically significant difference between them. The distribution of the frequency of people with DVT according to age group showed that among the age groups of referring patients, the age range of more than 50 years and the age range of 40-50 had the highest frequency, respectively. The frequency distribution of patients with DVT according to heart disease showed that 13% of patients with DVT had heart disease and 87% did not have heart disease. Out of a total of 277 patients studied, 7.9% had kidney problems and 92.1% had no kidney problems. Also, 40.8% of patients had high blood pressure and 59.2% did not have high blood pressure.  Conclusion: The results of the present study showed that among the risk factors for the occurrence of DVT of the lower limbs, a history of heart disease, old age, kidney problems and blood pressure in the studied patients were indicators. On the other hand, other risk factors examined in this study were not very important and most of the patients lacked them.
