Background: Vena cava filters are an important alternative when anticoagulation is contraindicated. Techniques for placement of inferior vena cava (IVC) filters have undergone continued evolution from open surgical exposure of the venous insertion site to percutaneous insertion in most cases .Today, all of the commonly used filters can be placed via a peripheral vein by using percutaneous puncture. Increased experience with color flow duplex scanning for routine IVC imaging and portability of ultrasound equipment have suggested the usefulness of duplex-guided IVC filter insertion (DGFI). Objective: Comparing bedside trans-abdominal duplex ultrasound versus contrast venography for inferior vena cava filter placement as regard to safety, efficacy , results and possible complications. Patients and Methods: This was a comparative study which included 30 patients divided into two groups: Group A which contained 15 patients by which filter placement was done by contrast venography in Al-Hussein Hospital, and Group B which contained 15 patients by which filter placement was done by duplex ultrasound in Al- Zahraa Hospital. History, complete examination and investigations were done to all the patients. Results:  There was a difference between both groups according to the age, gender, pulmonary embolism attack , indications for IVC filter deployment and the venous access aproach but insignificant, All filters were permenant and most common indication was recurrent tromboembolism insbite of adequate anticoagulation. Two patients in Group A suffered from hematoma and echymosis at access site, and filter deployment failed for the first time in two patients of Group B, but succeeded for the second time with no mortality detected. Conclusion: Inferior vena cava filter insertion was safe and effective in preventing pulmonary embolism. Fluroscopy has traditionally been the golden standard procedure for IVC filter deployment. Duplex guidance can replace fluoroscopy to guide the procedure in patients whose conditions can not tolerate the contrast material or exposure to X-ray.  The current study suggested that duplex guided filter insertion was safe, reliable, and accurate as the fluoroscopy guided procedure. Duplex guided method has proved to be cost effective as it can be done as a bedside procedure.  Obesity constituted the major technical limitation of duplex guided procedure.
