The Ottawa Score Performs Poorly to Identify Cancer Patients at High Risk of Recurrent Venous Thromboembolism: Insights from the TROPIQUE Study and Updated Meta-Analysis.

The Ottawa score (OS) for predicting the risk of recurrent venous thromboembolism (VTE) in cancer patients with VTE may help to guide anticoagulant treatment decisions that will optimize benefit-risk ratios. However, data on its reliability are conflicting. We applied the OS to all cancer patients with VTE enrolled in the prospective multicenter TROPIQUE study who received low-molecular-weight heparin over a 6-month period.

Pharmaco-mechanical catheter-directed thrombolysis versus recanalization and stenting for post thrombotic syndrome after lower limb deep vein thrombosis: a comparative study.

Background: Endovenous interventional procedures can be used in addition to therapeutic anticoagulation to treat deep vein thrombosis in selected patients with proximal vein involvement (vena cava, iliac and/or common femoral). The aim of this study was to compare venous patency and the post-thrombotic syndrome (PTS) in patients treated with pharmaco-mechanical catheter-directed thrombolysis (PMT) versus recanalization-stenting for PTS after a proximal lower limb deep vein thrombosis.

Methods: Between January 2014 and December 2020, this retrospective and monocentric study included patients with very symptomatic acute iliofemoral deep vein thrombosis treated with PMT within 21 days after diagnosis (PMT group) and patients with PTS caused by chronic venous obstruction treated with recanalization and stenting (CRS group).

Case-Control Study on Exercise-Induced Vasculitis in Hikers.

The aim of this study was to identify clinical factors associated with exercise-induced vasculitis (EIV). This study included EIV cases and controls matched for age. Cases included were all members of a hiking club and participated in extended hiking trips.

Risk factors for symptomatic vascular events in giant cell arteritis: a study of 254 patients with large-vessel imaging at diagnosis.

Aims: To identify factors associated with vascular events in patients with giant cell arteritis (GCA).

Methods: We performed a retrospective study of GCA patients diagnosed over a 20-year-period, who all underwent vascular imaging evaluation at diagnosis. Symptomatic vascular events were defined as the occurrence of any aortic event (aortic dissection or symptomatic aortic aneurysm), stroke, myocardial infarction, limb or mesenteric ischemia and lower limbs arteritis stage 3 or 4.

Large-vessel involvement is predictive of multiple relapses in giant cell arteritis.

Background: Giant cell arteritis (GCA) is the most common systemic vasculitis. Relapses are frequent. The aim of this study was to identify relapse risk factors in patients with GCA with complete large-vessel imaging at diagnosis.

Digital ischaemia aetiologies and mid-term follow-up: A cohort study of 323 patients.

Upper extremity digital ischaemia (UEDI) is a rare heterogeneous condition whose frequency is 40 times less than that of toe ischaemia. Using a large cohort, the aim of this study was to evaluate aetiologies, prognosis and midterm clinical outcomes of UEDI.All patients with UEDI with or without cutaneous necrosis in a university hospital setting between January 2000 to December 2016 were included.

Predictive factors of venous recanalization in upper-extremity vein thrombosis.

Background: Upper extremity venous thrombosis (UEVT) represents about 10% of venous thrombo-embolic disease. This is mainly explained by the increasing use of central venous line, for oncologic or nutritional care. The factors associated with venous recanalization are not known.

Prevalence of post-thrombotic syndrome in a cohort of upper extremity vein thrombosis.

Objective: Post-thrombotic syndrome (PTS) is one of the main complications that occurs after venous thrombosis. There are few data on the proportion of patients that will develop upper extremity PTS (UE-PTS) after upper extremity venous thrombosis (UEVT). The main objective of the study was to assess the prevalence of PTS in a UEVT cohort and to identify predictive factors of UE-PTS.

Effect of cannabis consumption on characteristics and evolution of thromboangitis obliterans.

Thromboangiitis obliterans (TAO) is a distal non atherosclerotic thrombotic vasculitis affecting tobacco smokers. The role of cannabis co-exposure remains controversial. The study aims to assess how cannabis consumption influences clinical presentation and outcome of TAO in tobacco smokers.

Symptomatic aortitis at giant cell arteritis diagnosis: a prognostic factor of aortic event.

Background: Giant cell arteritis (GCA) is frequently associated with aortic involvement that is likely to cause life-threatening structural complications (aneurysm, dissection). Few studies have investigated the occurrence of these complications, and no predictive factor has been identified so far. The aim of this study was to investigate factors associated with the risk of aortic complications in a cohort of GCA aortitis.

[Susceptibility genetics of common conditions in clinical practice].

The genetic tests for "non-rare thrombophilias" (TNR) were introduced into clinical setting immediately after the identification of genetic variants in the mid-90s to predict and prevent venous thromboembolism (VTE). Although being a rare example of a genetic test of susceptibility for complex diseases that has been integrated in medical routine, it is the most widespread post-natal genetics inquiry in France nowadays. Yet, determining whom to test and how to use the results is still controversial.

Upper extremity vein thrombosis (UE-VT) are more and more frequent pathologies and yet little studied. The aim is to describe the clinical and ultrasound features, UE-VT-related diseases, and the prevalence of pulmonary embolism (PE) and associated deaths.All UE-VT patients diagnosed by Doppler-ultrasound in Nantes University Hospital, from January 2015 to December 2017, were included retrospectively.

Understanding the Pathophysiology of Intracranial Aneurysm: The ICAN Project.

Background: Understanding the pathophysiologic mechanism of intracranial aneurysm (IA) formation is a prerequisite to assess the potential risk of rupture. Nowadays, there are neither reliable biomarkers nor diagnostic tools to predict the formation or the evolution of IA. Increasing evidence suggests a genetic component of IA but genetics studies have failed to identify genetic variation causally related to IA.
