The incidence of symptomatic thrombosis is between 2.4 and 6.8 per 1000 neonatal intensive care unit admission while it is 5.1 per 100 000 live births. Compared to adults, the anticoagulant and fibrinolytic system of newborns is significantly different. In this study, the aim is to evaluate infants with neonatal thrombosis in our unit to characterize acquired and genetic risk factors, the laboratory work-up parameters and the diagnosis approach.
In case of acute portal vein thrombosis (PVT) prothrombotic factors are identified in about 60% of cases, while a local condition is present in 30% of cases. Prothrombotic factors may indicate a long term anticoagulant therapy whereas the risk of recurrence seems low when a local condition is isolated (cholecystitis, angiocholitis, liver abces, diverticulitis, appendicitis, acute/chronic pancreatitis, chronic bowel inflammatory disease, acute hepatitis due to cytomegalovirus, bacteroïdes pylephlebitis, abdominal neoplasia such as adenocarcinoma of the colon, abdominal traumatism or surgery such as cholecystectomy, bariatric surgery or splenectomy). To date the impact of prothrombotic factors associated with local conditions responsible for acute PVT has not been well studied except for acute or chronic pancreatitis. No significant association has been pointed out in this pathology. The aim is to determine what are the risk factors of thrombotic recurrence or extension associated with local conditions responsible for acute non cirrhotic PVT, and to evaluate the rate of secondary long term anticoagulant therapy.
The purpose of this study is to determine whether Apixaban is effective and safe in Prevention of Portal Vein Thrombosis in Liver Cirrhotic Patients after Laparoscopic Splenectomy and Azygoportal Disconnection
The ULTREC research project is designed to assess the safety of a negative strategy relying on Colour Doppler Ultrasound (CDUS) for excluding the diagnosis of a new thrombosis. The ULTREC project does not take into account the validity of the CDUS positive criteria used to confirm the diagnosis of Deep Vein Thrombosis (DVT) recurrence. The risk of considering only the negative strategy is to ignore the possibility of having an improvement in sensitivity and negative predictive value at the expense of specificity and positive predictive value and therefore to increase the false positive rate leading to an overdiagnosis of recurrence and an overtreatment, and a potential bleeding risk. In the ULTREC-ANCILLARY study, the research will aim at assessing the validity of baseline CDUS positive criteria for the diagnosis of DVT recurrence. As there is no diagnostic standard to which the results could be compared, it is suggested to validate these criteria based on the evolution of the thrombosis on CDUS performed at D90±5. The hypothesis is that an unchanged appearance under anticoagulation would be in favor of sequelae and will invalidate the initial diagnosis (diagnostic failure)
To see whether our increased dosing regimen of unfractionated heparin (UF) and low molecular weight heparin (LMWH) in COVID-19 patients was effective at preventing thrombo-embolic complications. We did regular anti-Xa tests to optimise the dose of our thromboprophylaxis. Furthermore, we want to examine the time it takes to reach adequate anti-Xa levels, to determine additional risk factors and do a subgroup analysis. Lastly, we will study if there are possible complications of our thromboprophylactic therapy.
Open label randomized controlled clinical trial to evaluate the efficacy and safety of apixaban versus warfarin in treating left ventricular thrombus in patients with acute or recent myocardial infarction (MI).
Nephroblastoma (Wilms tumor) is the most common kidney tumor in children. It is a malignant embryonic tumor with a good prognosis with more than 85% long-term survival with appropriate chemotherapy, surgery (which most often consists of a total nephrectomy) and radiotherapy for locally invasive forms. Some nephroblastomas (approximately 10%) present with vascular extension with vena cava thrombus, a situation which may worsen the prognosis due to the complexity of the surgery. While the oncological treatment of nephroblastoma is highly formalized, to date there is no specific guideline on the surgical management of this rare clinical presentation of nephroblastomas. The aim of the study is to provide recommendations for the surgical management of nephroblastomas with vena cava thrombus in a large multicenter series.
Thromboembolisms (TEs) in patients with critical COVID-19 has been reported to be three times higher than for other critically ill patients. Immunothrombosis has been proposed as a plausible mechanism for COVID-19 coagulopathy. Corticosteroids improve survival in patients with critical COVID-19, and likely even more so with a higher dose. However, the evidence regarding the impact on the incidence of thromboembolic and bleeding events are currently uncharted. The aim of this study is to investigate if there is a difference in the incidence of thromboembolic events during ICU stay in patients with critical COVID-19 when treated with 12 mg dexamethasone compared to 6 mg dexamethasone.
This study compares the efficacy and safety of direct mechanical thrombectomy versus bridging therapy in patients with anterior circulation large vessel occlusion in a cohort of patients treated at the stroke unit of a single centre at Alexandria University in Egypt.
