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...

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...

BACKGROUND AND OBJECTIVE: Patients with loculated tuberculous pleurisy (TBP) treated with urokinase suffer less from residual pleural thickening (RPT) than those treated with simple drainage. However, the role of intrapleural urokinase in free-flowing TBP patients remains unclear. METHODS: A total of 318 patients with presumed TBP were screened. The final 171 patients who participated in the study were randomly allocated to the urokinase group (n = 86) and the control group (n = 85)...

Increased plasma level of soluble urokinase-type plasminogen activator receptor (suPAR) was associated recently with focal segmental glomerulosclerosis (FSGS). In addition, different clinical studies observed increased concentration of suPAR in various glomerular diseases and in other human pathologies with nephrotic syndromes such as HIV and Hantavirus infection, diabetes and cardiovascular disorders. Here, we show that suPAR induces nephrin down-modulation in human podocytes. This phenomenon is mediated only by full-length suPAR, is time-and dose-dependent and is associated with the suppression of Wilms' tumor 1 (WT-1) transcription factor expression...

Middle cerebral artery (MCA) occlusion was examined with basi-parallel anatomical scanning (BPAS) using three-dimensional fast imaging employing steady-state acquisition (3D-FIESTA), and 3D-FIESTA and magnetic resonance angiography (MRA) fusion images were created. We expected that an incidence of hemorrhagic complications due to vessel perforations would be decreased by obtaining vascular information beyond the occlusion and thus acute endovascular revascularization could be performed using such techniques...

Currently, permanent catheters (pCVC) are becoming an alternative vascular access for long-stay patients in whom arteriovenous access cannot be made. Occlusion is a commun mechanical complication related to pCVC, leading to inadequate dialysis dose and frequent changes of local catheter location, which can cause exclusion of vascular sites. The aim of this study was to perform a narrative review of treatment of pCVC thrombotic occlusion in HD patients. The treatment of CVCP thrombosis typically consists on the saline infusion or administration of thrombolytics such as tissue plasminogen activated, reteplase and urokinase...

BACKGROUND: Systemic thrombolysis for acute pulmonary embolism (PE) carries up to a 20% risk of major bleeding, including a 2% to 5% risk of hemorrhagic stroke. We evaluated the safety and effectiveness of catheter-directed therapy (CDT) as an alternative treatment of acute PE. METHODS: One hundred one consecutive patients receiving CDT for acute PE were prospectively enrolled in a multicenter registry. Massive PE (n = 28) and submassive PE (n = 73) were treated with immediate catheter-directed mechanical or pharmacomechanical thrombectomy and/or catheter-directed thrombolysis through low-dose hourly drug infusion with tissue plasminogen activator (tPA) or urokinase...

ETHNOPHARMACOLOGICAL RELEVANCE: Brownea grandiceps flowers are used in Venezuelan folk medicine as anti-hemorrhagic in women with heavy menstrual blood loss (menorrhagia). However, prior to this study, there were no scientific investigations to support this fact, because the aqueous extract from Brownea grandiceps flowers had not been previously evaluated neither phytochemically nor biologically. The objective of this work was to evaluate in vitro the effects of aqueous extract from Brownea grandiceps flowers on the coagulation system and fibrinolysis...
