A 35-year-old man who previously underwent splenectomy for hereditary spherocytosis at age 29 visited our hospital complaining of fatigue that had started 7 days ago and right upper abdominal pain. Laboratory data showed increased white blood cell and eosinophil count accompanied by severe transaminitis and clotting abnormalities. Computed tomography scan showed multiple embolisms in the portal vein, superior mesenteric vein, right pulmonary artery, and inferior vena cava. Severe liver damage presumably caused by portal vein thrombosis was also observed...

The aim of the present study was to investigate the efficacy of recombinant human prourokinase (rhPro-UK) on thromboembolic stroke in rabbits. A total of 210 rabbits were used in experiments. The 180 thromboembolic stroke rabbits were divided into three therapeutic time windows with six groups in each time window (n=10). The model group was administered saline, the reagent groups were administered rhPro-UK (2.5×, 5× and 10×104 U/kg), and the positive control groups were administered 5×104 urokinase (UK) U/kg and 4...

We evaluated the efficacy and safety of human recombinant prourokinase ( rhpro-UK) on thromboembolic stroke in rats. 60 rats with thromboembolic stroke were divided into 6 groups (n = 10). The model group was given saline, the reagent groups were given rhpro-UK (5, 10, 20 × 104 U/kg), and positive control groups were given urokinase (UK) 10 × 104 U/kg and recombinant tissue plasminogen activator (rt-PA) 9mg/kg through intravenous infusion at 1.5h after embolism. And other 10 rats without occluded by autologous blood clots as the sham group were given saline...

INTRODUCTION: Acute peripheral arterial occlusions can be treated with intra-arterial catheter-directed thrombolysis as an alternative to surgical thromboembolectomy. Although less invasive, this treatment is time-consuming and carries a significant risk of haemorrhagic complications. Contrast-enhanced ultrasound using microbubbles could accelerate dissolution of thrombi by thrombolytic medications due to mechanical effects caused by oscillation; this could allow for lower dosages of thrombolytics and faster thrombolysis, thereby reducing the risk of haemorrhagic complications...

The present study aimed to examine the feasibility of catheter-directed thrombolysis (CDT) using continuous infusion of low-dose urokinase in combination with low molecular weight heparin (LMWH) for acute iliofemoral venous thrombosis. This retrospective analysis included patients with symptomatic acute iliofemoral venous thrombosis who received CDT using continuous infusion of low-dose urokinase in combination with LMWH within the past four years. Urokinase was administered at 1×10(4) U/h and 2×10(4) U/h in patients at high-risk and low-risk of bleeding, respectively...

Plasminogen activator inhibitor-1 (PAI-1) is known to protect mice against cardiac fibrosis. It has been speculated that PAI-1 may regulate cardiac fibrosis by inactivating urokinase-type plasminogen activator (uPA) and ultimately plasmin (Pm) generation. However, the in vivo role of PAI-1 in inactivating uPA and limiting the generation of Pm during cardiac fibrosis remains to be established. The objective of this study was to determine if the cardioprotective effect of PAI-1 is mediated through its ability to directly regulate urokinase -mediated activation of plasminogen (Pg)...

Therapeutic fibrinolysis has been dominated by the experience with tissue-type plasminogen activator (t-PA), which proved little better than streptokinase in acute myocardial infarction. In contrast, endogenous fibrinolysis, using one-thousandth of the t-PA concentration, is regularly lysing fibrin and induced Thrombolysis In Myocardial Infarction flow grade 3 patency in 15% of patients with acute myocardial infarction. This efficacy is due to the effects of t-PA and urokinase plasminogen activator (uPA). They are complementary in fibrinolysis so that in combination, their effect is synergistic...

Thrombotic occlusion of central venous catheters (CVCs) is a common problem in newborns. No guideline systematically addresses the diagnosis, management, and prevention of this complication. The objective of this review is to establish evidence-based guidance for the management of CVC thrombosis. A comprehensive literature search was conducted from 1948 to 2012. Twenty-six articles fulfilling four criteria - humans, neonates aged less than 28 days, CVC insertion, and English language - were included for analysis...

BACKGROUND AND PURPOSE: We hypothesized that permanent stenting may be a rescue treatment for stentriever-failed anterior circulation large artery occlusion. We compared the outcomes among patients with permanent stenting and those without stenting after stentriever failure. METHODS: We retrospectively evaluated 208 patients who underwent stentriever thrombectomy for anterior circulation large artery occlusion between September 2010 and September 2015. Modified thrombolysis in cerebral ischemia 2b-3 recanalization was achieved with stentriever alone or in combination with Penumbra device in 155 patients (74...

PURPOSE: To evaluate a new endovascular strategy utilizing a hybrid procedure for long segmental arterial thromboembolism in a lower extremity by historical comparison with conventional endovascular strategy. MATERIALS AND METHODS: In a new endovascular strategy, a hybrid procedure was performed for long segmental thromboembolism (longer than 15 cm) and an endovascular procedure for short segmental thromboembolism. The new strategy group (Group A) consisted of 24 procedures (13 hybrid procedures, 11 endovascular procedures) in 19 patients...

We report our experience using catheter-directed thrombectomy/thrombolysis (CDT) to treat a patient with acute renal vein thrombosis (RVT) associated with systemic lupus erythematosus (SLE). A 34-year-old woman presented with persistent left flank pain, and a renal ultrasonography examination revealed an enlarged left kidney. Contrast-enhanced computed tomography confirmed the presence of acute left RVT. Because medical treatment failed to relieve her pain and the renal function was deteriorating, we attempted to salvage the occluded left renal vein using an endovascular approach...

A blood clot or thrombus triggers the onset of most vascular diseases, like stroke or heart attack. Thrombolysis is the only treatment that can restore blood flow rapidly and easily. Unfortunately, the standard thrombolytic, tissue plasminogen activator (tPA), has proven inadequate and is being replaced by invasive endovascular procedures, which are time consuming and limited in their availability in relation to the scope of the problem. Historically, when tPA clinical trials began, it was not recognized sufficiently that without the other natural plasminogen activator, prourokinase (proUK), thrombolysis by tPA was seriously compromised...

The article deals with the results of combined treatment of patients with pulmonary thromboembolism by means of systemic thrombolytic therapy, anticoagulant therapy, and rheolytic thrombectomy during the period from 2012 to 2013. Thrombolytic therapy was used in 78 of 187 patients with the confirmed diagnosis of pulmonary thromboembolism (Group 1). The diagnosis was verified and therapeutic results were controlled by means of contrast-enhanced spiral computed tomography and perfusion scintigraphy. Thrombolysis was carried out using: tissue plasminogen activator - alteplase (61 cases) with administration of the full dose during 2 hours, streptokinase (14 cases) at a dose of 1...
