Filter by:The frequency of violence against women, or intimate partner violence (IPV) is more and more underlined and recognized as a cofactor favoring certain somatic and psychic pathologies. However, its incidence in patients with venous thromboembolism (VTE) is unknown and its status as a risk factor is still elusive and ambiguous. Investigators therefore conducted a matched case-control study consisting of women taking combined oral contraceptives (COC) who were investigated and followed up between 2010 and 2020. The cases are the patients investigated for their first venous thromboembolic event, The controls were women free of thrombosis who had regular gynecological checkups. Case-control pairs were matched on region of residence, age (+/- 2 years), duration of COC intake (+/- 4 months), COC type (2nd, 3rd or 4th generation).
The present study is a non-interventional retrospective chart review study assessing the prevalence of PNH-clones in patients with PNH risk-factors aged ≥14 years and treated at our hospital. The objective of this study is to develop a PNH screening tool on the hospital Electronic Health Record (EHR) system. An algorithm defining PNH risk groups is developed.
Despite optimal anticoagulation therapy of patients with proximal deep vein thrombosis (DVT), there is still high number of patients suffering from post-thrombotic syndrome (PTS) due to the chronic venous occlusion, suboptimal collateralization, and venous valvular dysfunction. Last two decades endovascular catheter-based treatment modalities have been tested and used in an attempt to reduce incidence and symptoms of PTS in selected patients. Especially, patients with extensive iliofemoral DVT have an increased risk of PTS. In an effort to accelerate thrombus dissolution or thrombus extraction, the endovascular removal of acute venous thrombus has been introduced as therapeutic option in patients with extensive iliofemoral DVT. Randomized trials of catheter-based strategies for thrombus removal have documented improved vein patency, preserved valves function, and reduced post-thrombotic syndrome. The aim of our study is to evaluate the safety and efficacy of different types of endovascular methods of treatment followed by anticoagulation therapy in patients with acute extensive DVT. Retrospective multicentre analysis of app 100 patients scheduled for endovascular treatment of extensive DVT. The results of mechanical/pharmacomechanical thrombectomy followed by local catheter directed thrombolysis (CDT), will be compared with CDT alone, or with ultrasound-accelerated thrombolysis. The 24-month incidence of PTS assessed by Villalta scoring system, major bleeding complications, the rate of venous recanalization, recurrence of DVT, and other end-points will be evaluated.
The aim of the study is to evaluate the safety and performance of the ClotTriever catheter in the treatment of patients with symptomatic iliofemoral deep vein thrombosis (DVT)
It is a retrospective cross-sectional study, where consecutive stroke patients with vessel occlusion on magnetic resonance angiography (MRA) will be included for the study for one year. The relation of Susceptibility vascular sign (SVS) on Susceptibility Weighted Imaging (SWI) with risk factors and territory involved and length of thrombus will correlated with the National Institutes of Health stroke scale (NIHSS).Among total number of patients included in this study the demographics of the patients will be calculated. Risk factors for stroke of the patients included in this study will tabulated. The site of occlusion will be tabulated. The mean NIHSS scale will be calculated. Presence of SVS in patients with MR angiography positive vessel occlusion will be calculate in percentage. Subgroup analysis of presence of SVS on SWI will be done. The mean length of the thrombus will be calculated in these patients with positive SVS. Correlation between SVS on SWI with the risk factor of the patient by using the chi-square test will be calculated. A Chi-square test will be done to find out the correlation between the SVS with territorial occlusion. The correlation between the NIHSS score and length of thrombus will be calculated using the Pearson test. SWI can be useful in identifying the location of the thrombus, and NIHSS can determine the thrombus length in acute stroke. A higher incidence of SVS can be associated with risk factors and it also depends upon the site of occlusion of the vessel.
The purpose of the study is to assess the safety and efficacy of rivaroxaban-based versus warfarin-based antithrombotic regimens on outcomes of patients with left ventricle thrombosis following acute ST elevation myocardial infarction at 3 months from enrollment in an open-label parallel groups pilot randomized clinical trial
Chemotherapy-induced thrombocytopenia (CIT) is a common hematological toxicity in patients with solid tumors undergo chemotherapy, which can increase the risk of bleeding, prolong hospital stay, increase medical costs, and even lead to death in severe cases. The incidence and severity of CIT varies among different chemotherapy regimens. Recombinant human interleukin-11 (rhIL-11) and recombinant human thrombopoietin (rhTPO) have been approved for the treatment of chemotherapy-induced thrombocytopenia. Tumor patients are at high risk for venous thromboembolism (VTE). In the clinical study of rhIL-11, it was found that the administration of rhIL-11 in healthy subjects caused an increase in the plasma concentration of vWF factor in the form of normal mults. The application of rhIL-11 in patients with myeloid leukemia can increase the concentration of α2 globulin, fibrinogen and prothrombin time. However, there have been no large-scale clinical studies at home and abroad to evaluate whether platelet raising therapy will increase the risk of thrombosis in chemotherapy patients with solid tumor. This study is aimed to evaluate the efficacy and safety of platelet upwelling therapy in patients with solid tumors undergoing chemotherapy.
Comparing the disposition time of point of care ultrasound (POCUS) versus formal lower extremity doppler in emergency department patients.
Intravenous (IV) recombinant tissue plasminogen activator is the standard of care for patients with acute ischemic stroke (AIS) who present to the hospital within 4.5 hours of symptom onset. However, IV thrombolysis, even bridging thrombolysis (combining intravenous thrombolysis and mechanical thrombectomy) has limited efficacy among patients who had occlusive lesions associated with highgrade arterial stenosis requiring revascularization to improve neurological deficits. The investigators evaluated whether rescue stenting results in good outcomes among patients after the failure of intravenous thrombolysis and bridging thrombolysis.
In this study, color Doppler ultrasound diagnostic instrument and electronic grip device were used to determine the best grip strength of patients with tumor PICC catheterization, formulate precise and standardized grip strength training guidance for them, provide personalized functional exercise health education, and observe the impact of precise grip strength training guidance on Peripheral central venous catheter-associated thrombosis. To provide a reference for clinical prevention of Peripheral central venous catheter-associated thrombosis in the future.
