Introduction: Patients undergoing surgical operations are at risk of deep vein thrombosis (DVT), considered one of the main causes of morbidity and mortality that has been gaining attention in the past two decades. The incidence of DVT could reach 1 in 1000 in the general population and varies from 1 in 10000 in under forties comparing to 1 in 100 in over eighties. Evidence-based strategies for Screening and investigations of DVT should be continuously upgraded based on good-quality recent trials. Data sources: Electronic Library databases until 2006. Randomized clinical trials and meta-analyses in which different screening and investigation techniques were reviewed and compared in patients with clinical suspicion of DVT. Conclusion: a combination of clinical assessment using Well’s score, D-dimer blood test and duplex ultrasound scan gives the highest sensitivity and specificity to evaluate patients suspected to have DVT in a non-invasive, cost effective process.
