Determination of the Relative Frequency of Lower limb Deep Vein Thrombosis Risk Factors in Patients Referred to Teaching Hospitals of Yasuj, Iran, 2013 to 2014

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 of Yasuj, Iran, from 2013 to 2014.

The present retrospective cross-sectional descriptive study was conducted in 2020. The participants of  study included 277 cases of DVT patients hospitalized in teaching hospitals of Yasuj, Iran. Furthermore, patients' characteristics such as 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. The collected data were analyzed using SPSS software and chi-square test.

The results of the present study indicated that 50.9% of DVT patients were women and 49.1% were men, and no statistically significant difference were observed between the two groups. The distribution of the frequency of people with DVT according to age group revealed that among the age groups of referring patients, the age range of above 50 years and the age range between 40 to 50 had the highest frequency, respectively. The frequency distribution of patients with DVT according to heart disease indicated that 13% of patients with DVT showed heart disease and 87% did not indicate heart disease. Out of a total of 277 patients studied, 7.9% had kidney problems and 92.1% had no sign of kidney problems. Furthermore, 40.8% of patients indicated high blood pressure and 59.2% did not show high blood pressure.

The results of the present study revealed 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 the present study were trivial and and were not observed in the participants of the present study.
