Prosthetic heart valve thrombosis (PHVT) is one of the major causes of primary valve failure. Even with the use of warfarin, risk of thromboembolism is 1-2% per year, but the risk is considerably higher without or inadequate treatment with warfarin (1). Although surgery is the first-line treatment modality in symptomatic PHVT (2), thrombolytic therapy has recently evolved as an effective substi...

This paper aims to study the thrombolytic effect of low-frequency ultrasound combined with targeted urokinase-containing microbubble contrast agents on treatment of thrombosis in rabbit femoral artery; and to determine the optimal combination of parameters for achieving thrombolysis in this model. A biotinylated-avidin method was used to prepare microbubble contrast agents carrying urokinase an...

Pulmonary vein thrombosis is difficult to diagnose clinically and requires a combination of conventional diagnostic modalities. Transesophageal echocardiography was used in the present case to readily diagnose this entity and follow thrombus regression on anticoagulant therapy. This limited experience suggests that transesophageal echocardiography may be the initial diagnostic study of choice f...

This article presents a review of the treatment of lower-extremity deep venous thrombosis (DVT) with systemic and catheter-directed thrombolysis (CDT) and percutaneous mechanical thrombectomy (PMT). Standard treatment including anticoagulation therapy and compression stockings may not be entirely adequate, because a significant proportion of patients eventually develop post-thrombotic syndrome ...

background: we sought to evaluate the efficacy and safety of the different trade forms of streptokinase available in our country, namely heberkinasa (heberbiotec, havana, cuba) and streptase (aventis behring gmbh, marburg, germany). methods: we conducted a double-blind randomized clinical trial to compare the two streptokinase formulations, i.e. heberkinasa (hbk) or streptase (stp), in patients...

Acute intracranial dural sinus thrombosis may have severe morbidity or fatal complications without appropriate treatment. Direct dural sinus venography can be performed safely with a soft Tracker catheter to document the fresh thrombus as an adjunct to CT or MR. We are reporting our experience with successful direct urokinase thrombolytic therapy in three cases of superior sagittal sinus and tw...

Currently, the only widely accepted indication for thrombolysis in cases of pulmonary embolism is hemodynamic instability. However, the presence of a right-heart thrombus along with pulmonary embolism is a poor prognostic indicator, and the use of thrombolytic agents should also be considered in this circumstance. Furthermore, despite a risk of distal embolization, thrombolytic therapy may be i...
