Introduction: Deep vein thrombosis is a significant postoperative complication associated with increased morbidity and mortality. Identifying risk factors and implementing preventive measures are crucial in surgical patients to reduce complications. Objective: To determine the incidence of DVT among surgical patients and analyse the demographic and risk factors contributing to its occurrence. Methodology: Data was collected from 100 patients undergoing surgical procedures. Patients were evaluated using duplex scanning for DVT diagnosis, and relevant demographic, clinical, and procedural data were collected. Factors such as age, type of surgery, duration of surgery, postoperative mobilization timewere analysed. Results: The incidence of asymptomatic DVT was 6%, through duplex scanning. The majority of patients were middle-aged (40–59 years). Elective surgeries accounted for 77% of cases.Prolonged surgical durations (>420 minutes) were observed in 13% of cases, and delayed mobilization beyond nine days was seen in 15% of patients, both contributing to increased DVT risk. Conclusion: Although the incidence of DVT was relatively low, the study highlights the importance of early screening, thromboprophylaxis, and timely postoperative mobilization. Patients with prolonged operative timesrequire targeted preventive strategies.
