Background: Deep venous thrombosis (DVT) is an a major public health concern and important cause of
morbidity and mortality worldwide; with an estimated annual incidence in developed countries 1 to 2 per 1,000
people each year. The study aimed to assessrisk factorsfor deep venous thrombosis among patients admitted to
vascular unit through Assessing patients' demographic characteristics, patients' educational needsregarding DVT
and risk factors that lead to developing of DVT. Study design: a descriptive exploratory design was be utilized.
Setting: this study was conducted at vascular surgical unit of Sohag university hospitals. Subjects: A purposive
sample of 75 Patients with DVT were be recruited in the study. Tools of data collection: (1) patient structured
interview questionnaire & (2) DVT risk factor assessment Tool. Results: More than half of the studied patients
had unsatisfactory level of knowledge towardsrisk factorsfor DVT. Major ofthe studied patients had immobility,
fracture, obesity, stroke, malignancy and chemotherapy as risk factors for DVT. There was a significant
relation between risk assessment scale for DVT with total knowledge, patients' habits, age, gender, past
medical &surgical history and body mass index of the studied patients Conclusion: There were many risk
factorsfor DVT incidence, the most common risk factorsrelated to patients daily habits. While family history and
activity of daily living related factors were the least common risk factors. It was concluded that taking oral
contraceptive pills were considered significant risk factor for DVT among female studied patients. There was a
significant positive correlation between educational level and patients' total knowledge regarding
DVT .Recommendation: Designing educational program for patients with DVT to improve their knowledge
regarding risk factors for deep vein thrombosis and its potential associated complications with submission of
