Fibrinography and thrombography (thrombodynamics-4D) in atrial fibrillation assessment of direct oral anticoagulants in geriatrics patients aged 80 years and older receiving direct oral anticoagulant therapy.

Background: Scarce data are available on pharmacodynamic (PD) variability in very elderly patients receiving direct oral anticoagulants (DOACs) for atrial fibrillation (AF). Thrombodynamics-4D (TD-4D), which simultaneously assesses fibrin clot formation and thrombin generation, has not yet been tested in patients on rivaroxaban, apixaban, or dabigatran.

Objectives: To (i) evaluate TD-4D's ability to assess DOAC effect added to normal plasma; (ii) assess DOAC PD in very elderly patients with AF along with DOAC concentrations; (iii) identify factors associated with interindividual variability of DOAC PD at peak and trough levels.

Predictive factors for complete recovery of post-thrombotic syndrome 6 months after venous recanalization.

Objective: Endovascular recanalization is considered for severely symptomatic patients with post-thrombotic syndrome (PTS) to alleviate symptoms. However, data on complete recovery and its predictors remain limited. This study aimed to assess persistent PTS 6 months after venous recanalization and identify predictive factors.

Evaluation of Ultrasound Microflow Imaging as an Assessment Tool for Digital Arteries in Thromboangiitis Obliterans.

Purpose: Thromboangiitis obliterans (TAO) diagnosis is challenging, and arterial imaging plays a major role in identifying distal artery occlusions. The ultrasonic micro-flow imaging (MFI) mode aims to identify small vessels better using high frame rates and adapted filters. Our objective was to compare the digital arterial characterization performance of MFI with digital subtraction angiography (DSA).

Advancements in Noncontrast Ultrasound Imaging for Low-Velocity Flow: A Technical Review and Clinical Applications in Vascular Medicine.

Visualizing the arterial tree using ultrasound, from the aorta to the small vessels, has significantly improved over time due to advances in ultrasound imaging technology. Initially limited to exploring the major vessels, ultrasound analysis has made considerable progress with enhanced image quality. While injecting microbubbles as a contrast agent partially addresses this limitation, its use is constrained by the need for intravenous injection, making the examination more complex and time-consuming.

Cutting-edge European guidelines for managing lower extremity peripheral arterial disease - Featuring selected insights on PAD management.

The new guidelines for the management of peripheral arterial and aortic diseases (PAAD) from the European Society of Cardiology and endorsed by the European Society of Vascular Medicine (ESVM), emphasize on a comprehensive and multidisciplinary approach focusing on prevention, diagnosis, treatment, and follow-up of patients with a wide range of PAAD, including lower extremity peripheral arterial disease (PAD). The aim of this summary, focusing on PAD and coordinated by the Young Academy of ESVM, is to provide young angiologists with the fundamental principles of these guidelines and to assist them in navigating their everyday clinical practice. PAD diagnosis relies on objective evaluation of flow/oxygen reduction at rest, with arterial ultrasound as the first imaging modality to confirm the presence of arterial lesions.

Efficacy of Irbesartan in Celiprolol-Treated Patients With Vascular Ehlers-Danlos Syndrome.

Background: Vascular Ehlers-Danlos syndrome is a rare genetic disorder characterized by defective type III collagen and a high risk of arterial morbidity and mortality. Several cardiovascular drugs are used for treatment, including celiprolol, but no controlled trial in this condition has been conducted to date. We hypothesized the benefit of the addition of an angiotensin II receptor blocker.

Histological pattern of non-infectious thoracic aortitis impacts mortality.

Background: Non-infectious aortitis encompasses various histological patterns, but their specific cardiovascular outcomes remain unclear.

Objective: To evaluate the mortality associated with non-infectious surgical thoracic aortitis.

Methods: This retrospective multicenter study included patients who underwent thoracic aortic surgery and had histological evidence of aortitis.

Impact of gender on self-assessment accuracy among fourth-year French medical students on faculty's online Objective Structured Clinical Examinations.

Background: Historically, women have been shown to underestimate their abilities, while men often assess themselves more accurately or overestimate. This study aims to determine self-assessment accuracy during online Objective Structured Clinical Examinations (OSCEs) according to gender.

Methods: A prospective study was conducted among fourth-year medical students at Paris Cité University during faculty training OSCEs, utilizing Zoom® software for remote participation.

Assessment of microvascular flow in human atherosclerotic carotid plaques using ultrasound localization microscopy.

Background: Neovascularisation of carotid plaques contributes to their vulnerability. Current imaging methods such as contrast-enhanced ultrasound (CEUS) usually lack the required spatial resolution and quantification capability for precise neovessels identification. We aimed at quantifying plaque vascularisation with ultrasound localization microscopy (ULM) and compared the results to histological analysis.

Positivity of antiphosphatidylserine/prothrombin antibodies identifies a subgroup of more severe antiphospholipid syndrome patients.

Objectives: Antiphospholipid syndrome (APS) is an autoimmune disease combining the occurrence of thrombotic and/or obstetric events with the persistent presence of antiphospholipid antibodies (i.e. lupus anticoagulant (LA), anti-cardiolipin (aCL) and anti-beta-2-glycoprotein I (aβ2GPI) antibodies).

L-Wnk1 Deletion in Smooth Muscle Cells Causes Aortitis and Inflammatory Shift.

Background: The long isoform of the Wnk1 (with-no-lysine [K] kinase 1) is a ubiquitous serine/threonine kinase, but its role in vascular smooth muscle cells (VSMCs) pathophysiology remains unknown.

Methods: AngII (angiotensin II) was infused in to induce experimental aortic aneurysm. Mice carrying an allele were cross-bred with mice carrying a floxed allele to specifically investigate the functional role of Wnk1 in VSMCs.

Challenges and opportunities in the management of type 2 diabetes in patients with lower extremity peripheral artery disease: a tailored diagnosis and treatment review.

Lower extremity peripheral artery disease (PAD) often results from atherosclerosis, and is highly prevalent in patients with type 2 diabetes mellitus (T2DM). Individuals with T2DM exhibit a more severe manifestation and a more distal distribution of PAD compared to those without diabetes, adding complexity to the therapeutic management of PAD in this particular patient population. Indeed, the management of PAD in patients with T2DM requires a multidisciplinary and individualized approach that addresses both the systemic effects of diabetes and the specific vascular complications of PAD.

Targeted therapy for capillary-venous malformations.

Sporadic venous malformations are genetic conditions primarily caused by somatic gain-of-function mutation of PIK3CA or TEK, an endothelial transmembrane receptor signaling through PIK3CA. Venous malformations are associated with pain, bleedings, thrombosis, pulmonary embolism, esthetic deformities and, in severe cases, life-threatening situations. No authorized medical treatment exists for patients with venous malformations.

Acute phase determinant of post-thrombotic syndrome: A review of the literature.

Background: Post-thrombotic syndrome (PTS) is the main long-term complication of deep vein thrombosis (DVT). Several therapies are being evaluated to prevent or to treat PTS. Identifying the patients most likely to benefit from these therapies presents a significant challenge.

Clinical spectrum and outcome of Takayasu's arteritis in children.

Objectives: We aimed to compare clinical spectrum and outcome between adults and children with Takayasu's arteritis (TAK) in a European population.

Methods: We made a nationwide retrospective observational study between 1988 and 2019. All adult patients met the ACR diagnostic criteria for TAK and all children met the EULAR/PRINTO/PRES criteria for paediatric TAK.

Vasa vasorum interna in the carotid wall of active forms of Takayasu arteritis evidenced by ultrasound localization microscopy.

Takayasu arteritis (TA) is associated with microvascularization of the wall of large arteries and is related to inflammation. Ultrasound localization microscopy (ULM), combining ultrafast ultrasound imaging with microbubble (MB) injection, can track the path of MBs within the arterial wall and thus provide imaging of the vasa vasorum. From the analysis of MB tracks in the common carotid arteries of patients with active TA, we report the presence of microvessels in connection with the carotid lumen (i.

Symptomatic Upper Extremity Peripheral Artery Disease is Associated With Poor Outcomes and a Broad Spectrum of Etiologies.

The symptomatic upper extremity peripheral artery disease (sUE-PAD) is poorly studied compared with the lower extremity peripheral artery disease (LE-PAD). We aimed to describe sUE-PAD etiologies and outcomes at 2 years. From an observational survey conducted in two French tertiary hospitals, demographic characteristics, etiology, treatment, and outcomes during follow-up were collected on patients with ICD-10 I74.

Fluoroquinolone Use Preceding Visceral Artery Dissection: A Case Series.

Fluoroquinolones (FQ), commonly prescribed antibiotics, may trigger aortic and carotid dissections. We report three successive cases of visceral artery dissection: one patient with celiac trunk dissection and two with dissection of the superior mesenteric artery. These events occurred up to 4 months after 7 to 14 days of FQ treatment (2 cases of ofloxacin, 1 of norfloxacin).

The fundamental mechanisms of the Korotkoff sounds generation.

Blood pressure measurement is the most widely performed clinical exam to predict mortality risk. The gold standard for its noninvasive assessment is the auscultatory method, which relies on listening to the so-called "Korotkoff sounds" in a stethoscope placed at the outlet of a pneumatic arm cuff. However, more than a century after their discovery, the origin of these sounds is still debated, which implies a number of clinical limitations.
