Background Deep venous thrombosis (DVT) is a major cause of morbidity and mortality all-over the world. Complications include pulmonary embolism (PE), post-thrombotic syndrome (PTS), phlegmasia alba dolens, phlegmasia cerulea dolens and venous gangrene. The PTS is the most common cause of long-term morbidity and disability among the previous complications. Aim of the Work The aim of this work is evaluation of the regional catheter-directed thrombolytic therapy versus standard systemic anticoagulant therapy in cases of acute ilio-femoral deep vein thrombosis as regard to efficacy, safety as well as complications. Patients and Methods This study was conducted on 30 patients presented to the vascular surgery unit of Ahmed Maher Teaching Hospital between February, 2019 and August, 2019 with acute iliofemoral deep venous thrombosis (less than two weeks duration). Of the 30 patients, 18 were females and 12 were males. The age of the patients ranged between 22 and 55 years. Results The outcome results of early Follow up of the thrombolytic therapy was complete recanalization in 30.7% of the cases, partial re-canalization in 53.8% of the cases and poor recanalization in the remaining cases15.3%.While the follow up results of anticoagulant therapy was complete re-canalization in 6.7% of the cases, partial re-canalization in 60% of cases and poor recanalization in the remaining cases 33.3% Conclusion Catheter directed thrombolytic therapy using streptokinase, as a lytic agent in the treatment of acute ilio-femoral DVT is a safe and efficient technique.
