Filter by:The objective of this retrospective, prospective, multicenter cohort study is to determine the risk factors for deterioration of CVT patients after admission and establish a scoring model for risk stratification of patients. This study included two stages, the first stage was to enroll CVT patients from a single center from 2017 to 2022 for modeling, and the second stage was to enroll CVT patients from three centers in 2023 for external validation
The purpose of this study is to identify and validate new imaging biomarkers allowing an individual phenotyping of patient with venous thrombo-embolism (VTE), mainly in terms of recurrence risk assessment and to distinguish provoked from unprovoked VTE. To do so, the investigators will create a retrospective imaging database including multiple imaging modalities, performed at diagnosis of the VTE.
The aim of the LATE (multidetector CT Lefi Appendage atrial Thrombosis Exclusion in patients with atrial fibrillation) study is to evaluate the diagnostic accuracy of cardiac Computed Tomography (TC) with 64 detectors and double acquisition phase in candidate patients ablation of atrial fibrillation (AF) with the Navx (or Carto) technique, using trans-esophageal ultrasound (TEE) as the standard reference. This study is based on the use of an experimental protocol in cardiac TC which involves, in addition to the acquisition of an early arterial phase (standard protocol routinely performed in all patients), the execution of a possible late phase at a very low dose of radiation (experimental protocol) aimed at increasing the accuracy of the method in the diagnosis in patients with AF. The LATE study aims to demonstrate the high diagnostic accuracy of dual acquisition phase cardiac TC in the diagnosis of intraauricular thrombosis by comparing it with reference standard; in light of this result, cardiac TC could constitute a single non-invasive diagnostic tool in the future for the global evaluation of both atrial anatomy and endoawicular thrombosis with a clear improvement in patient management both in clinical and economic terms.
Venous thromboembolism is prevalent, associated with a high degree of morbidity and mortality, and largely preventable. External mechanical compression is a standard of care for prevention, but compliance with traditional external mechanical compression devices is low due to patient reported issues with comfort, mobility, usability, noise, and sleep disturbances. The purpose of this study was to compare user-rated comfort, mobility, usability, noise, perceived sleep disturbance, and objective sleep disturbance for a novel external lower limb mechanical compression device as compared to a standard sequential compression device. Using a 2-day counterbalanced, within-subject repeated-measures design, 16 participants wore two mechanical compression devices, the commonly-used Kendall sequential compression device Express 9525 and the novel Recovery Force Movement and Compressions Device for 1 night each in their home while sleep was recorded with polysomnography. For each device, participants also completed questionnaires to assess usability, mobility, perceived noise disturbance, and perceived sleep disturbance.
Based on data on a cohort of 2,141 patients undergoing elective colonic cancer resection in an ERAS program, the incidence of postoperative thromboembolic events is estimated in patients no receiving prolonged thromboembolic prophylaxis.
The goal of this multicenter retrospective cohort study is to investigate the clinical outcomes and prognostic factors after hepatic resection in patients with HCC exhibiting PVTT, and to develop a prognostic index that can be helpful in determining the treatment strategy.
The cohort study aims to evaluate the efficacy and safety of steroids combined with anticoagulant therapy compared to standard anticoagulant therapy in acute/subacute severe cerebral venous thrombosis.
In this prospective cohort study, the investigators evaluated the incidence of superficial vein thrombosis, deep vein thrombosis, and fibroblastic sleeve formation in solid cancer patients undergoing chemotherapy. The study aimed to shed light on the clinical progression of venous thrombosis in cancer patients with central venous catheters, with a particular focus on certain cancer types associated with a higher risk of venous thromboembolism (VTE). The investigators believe that such findings hold significant clinical relevance as a substantial portion of the study population was affected by pancreatic cancer, a cancer type known to carry a high risk of thrombotic events. This research adds valuable insights into understanding asymptomatic PICC-related thrombosis in this specific subgroup of cancer patients, which can aid in developing effective management strategies for venous access in this challenging population. The study employed an ultrasound-guided approach for follow-up at 30 and 90 days after catheter insertion, enabling us to detect and treat asymptomatic PICC-VTE in a timely manner. Identifying independent risk factors for catheter-related thrombosis, including age and cancer type, has further enhanced the clinical applicability of our findings.
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.
